International Business Machines Corporation (IBM) is an American multinational information technology company headquartered in Armonk, New York, with operations in over 170 countries. The company began in 1911, founded in Endicott, New York, as the Computing-Tabulating-Recording Company (CTR) and was renamed "International Business Machines" in 1924.

IBM produces and sells computer hardware, middleware and software, and provides hosting and consulting services in areas ranging from mainframe computers to nanotechnology. IBM is also a major research organization, holding the record for most U.S. patents generated by a business (as of 2019) for 26 consecutive years. Inventions by IBM include the automated teller machine (ATM), the floppy disk, the hard disk drive, the magnetic stripe card, the relational database, the SQL programming language, the UPC barcode, and dynamic random-access memory (DRAM). The IBM mainframe, exemplified by the System/360, was the dominant computing platform during the 1960s and 1970s.

IBM has continually shifted business operations by focusing on higher-value, more profitable markets. This includes spinning off printer manufacturer Lexmark in 1991 and the sale of personal computer (ThinkPad/ThinkCentre) and x86-based server businesses to Lenovo (in 2005 and 2014, respectively), and acquiring companies such as PwC Consulting (2002), SPSS (2009), The Weather Company (2016), and Red Hat (agreement announced in October 2018, actual acquisition to be in the second half of 2019). Also in 2014, IBM announced that it would go "fabless", continuing to design semiconductors, but offloading manufacturing to GlobalFoundries.

Nicknamed Big Blue, IBM is one of 30 companies included in the Dow Jones Industrial Average and one of the world's largest employers, with (as of 2017) over 380,000 employees, known as "IBMers". At least 70% of IBMers are based outside the United States, and the country with the largest number of IBMers is India. IBM employees have been awarded five Nobel Prizes, six Turing Awards, ten National Medals of Technology (USA) and five National Medals of Science (USA).

History

In the 1880s, technologies emerged that would ultimately form the core of International Business Machines (IBM). Julius E. Pitrap patented the computing scale in 1885; Alexander Dey invented the dial recorder (1888); Herman Hollerith (1860–1929) patented the Electric Tabulating Machine; and Willard Bundy invented a time clock to record a worker's arrival and departure time on a paper tape in 1889. On June 16, 1911, their four companies were amalgamated in New York State by Charles Ranlett Flint forming a fifth company, the Computing-Tabulating-Recording Company (CTR) based in Endicott, New York. The five companies had 1,300 employees and offices and plants in Endicott and Binghamton, New York; Dayton, Ohio; Detroit, Michigan; Washington, D.C.; and Toronto

They manufactured machinery for sale and lease, ranging from commercial scales and industrial time recorders, meat and cheese slicers, to tabulators and punched cards. Thomas J. Watson, Sr., fired from the National Cash Register Company by John Henry Patterson, called on Flint and, in 1914, was offered a position at CTR. Watson joined CTR as General Manager then, 11 months later, was made President when court cases relating to his time at NCR were resolved. Having learned Patterson's pioneering business practices, Watson proceeded to put the stamp of NCR onto CTR's companies. He implemented sales conventions, "generous sales incentives, a focus on customer service, an insistence on well-groomed, dark-suited salesmen and had an evangelical fervor for instilling company pride and loyalty in every worker". His favorite slogan, "THINK", became a mantra for each company's employees. During Watson's first four years, revenues reached $9 million and the company's operations expanded to Europe, South America, Asia and Australia. Watson never liked the clumsy hyphenated name "Computing-Tabulating-Recording Company" and on February 14, 1924 chose to replace it with the more expansive title "International Business Machines". By 1933 most of the subsidiaries had been merged into one company, IBM.

In 1937, IBM's tabulating equipment enabled organizations to process unprecedented amounts of data, its clients including the U.S. Government, during its first effort to maintain the employment records for 26 million people pursuant to the Social Security Act, and the tracking of persecuted groups by Hitler's Third Reich, largely through the German subsidiary Dehomag

In 1949, Thomas Watson, Sr., created IBM World Trade Corporation, a subsidiary of IBM focused on foreign operations. In 1952, he stepped down after almost 40 years at the company helm, and his son Thomas Watson, Jr. was named president. In 1956, the company demonstrated the first practical example of artificial intelligence when Arthur L. Samuel of IBM's Poughkeepsie, New York, laboratory programmed an IBM 704 not merely to play checkers but "learn" from its own experience. In 1957, the FORTRAN scientific programming language was developed. In 1961, IBM developed the SABRE reservation system for American Airlines and introduced the highly successful Selectric typewriter. In 1963, IBM employees and computers helped NASA track the orbital flight of the Mercury astronauts. A year later, it moved its corporate headquarters from New York City to Armonk, New York. The latter half of the 1960s saw IBM continue its support of space exploration, participating in the 1965 Gemini flights, 1966 Saturn flights and 1969 lunar mission.

On April 7, 1964, IBM announced the first computer system family, the IBM System/360. It spanned the complete range of commercial and scientific applications from large to small, allowing companies for the first time to upgrade to models with greater computing capability without having to rewrite their applications. It was followed by the IBM System/370 in 1970. Together the 360 and 370 made the IBM mainframe the dominant mainframe computer and the dominant computing platform in the industry throughout this period and into the early 1980s. They, and the operating systems that ran on them such as OS/VS1 and MVS, and the middleware built on top of those such as the CICS transaction processing monitor, had a near-monopoly-level hold on the computer industry and became almost synonymous with IBM products due to their marketshare.

In 1974, IBM engineer George J. Laurer developed the Universal Product Code. IBM and the World Bank first introduced financial swaps to the public in 1981 when they entered into a swap agreement. The IBM PC, originally designated IBM 5150, was introduced in 1981, and it soon became an industry standard. In 1991, IBM sold printer manufacturer Lexmark

In 1993, IBM posted a US$8 billion loss - at the time the biggest in American corporate history. Lou Gerstner was hired as CEO from RJR Nabisco to turn the company around. In 2002, IBM acquired PwC consulting, and in 2003 it initiated a project to redefine company values, hosting a three-day online discussion of key business issues with 50,000 employees. The result was three values: "Dedication to every client's success", "Innovation that matters—for our company and for the world", and "Trust and personal responsibility in all relationships".

In 2005, the company sold its personal computer business to Chinese technology company Lenovo and, in 2009, it acquired software company SPSS Inc. Later in 2009, IBM's Blue Gene supercomputing program was awarded the National Medal of Technology and Innovation by U.S. President Barack Obama. In 2011, IBM gained worldwide attention for its artificial intelligence program Watson, which was exhibited on Jeopardy! where it won against game-show champions Ken Jennings and Brad Rutter. The company also celebrated its 100th anniversary in the same year on June 16. In 2012, IBM announced it has agreed to buy Kenexa, and a year later it also acquired SoftLayer Technologies, a web hosting service, in a deal worth around $2 billion.

In 2014, IBM announced it would sell its x86 server division to Lenovo for $2.1 billion. Also that year, IBM began announcing several major partnerships with other companies, including Apple Inc., Twitter, Facebook, Tencent, Cisco, UnderArmour, Box, Microsoft, VMware, CSC, Macy's, Sesame Workshop, the parent company of Sesame Street, and Salesforce.com.

In 2015, IBM announced three major acquisitions: Merge Healthcare for $1 billion, data storage vendor Cleversafe, and all digital assets from The Weather Company, including Weather.com and the Weather Channel mobile app. Also that year, IBMers created the film A Boy and His Atom, which was the first molecule movie to tell a story. In 2016, IBM acquired video conferencing service Ustream and formed a new cloud video unit. In April 2016, it posted a 14-year low in quarterly sales. The following month, Groupon sued IBM accusing it of patent infringement, two months after IBM accused Groupon of patent infringement in a separate lawsuit.

In October 2018, IBM announced its intention to acquire Red Hat for $34 billion.

Headquarters and offices

IBM is headquartered in Armonk, New York, a community 37 miles (60 km) north of Midtown Manhattan. Its principal building, referred to as CHQ, is a 283,000-square-foot (26,300 m2) glass and stone edifice on a 25-acre (10 ha) parcel amid a 432-acre former apple orchard the company purchased in the mid-1950s. There are two other IBM buildings within walking distance of CHQ: the North Castle office, which previously served as IBM's headquarters; and the Louis V. Gerstner, Jr., Center for Learning (formerly known as IBM Learning Center (ILC)), a resort hotel and training center, which has 182 guest rooms, 31 meeting rooms, and various amenities.

IBM operates in 174 countries as of 2016, with mobility centers in smaller markets areas and major campuses in the larger ones. In New York City, IBM has several offices besides CHQ, including the IBM Watson headquarters at Astor Place in Manhattan. Outside of New York, major campuses in the United States include Austin, Texas; Research Triangle Park (Raleigh-Durham), North Carolina; Rochester, Minnesota; and Silicon Valley, California

IBM's real estate holdings are varied and globally diverse. Towers occupied by IBM include 1250 René-Lévesque (Montreal, Canada), Tour Descartes (Paris, France), and One Atlantic Center (Atlanta, Georgia, USA). In Beijing, China, IBM occupies Pangu Plaza, the city's seventh tallest building and overlooking Beijing National Stadium ("Bird's Nest"), home to the 2008 Summer Olympics

IBM India Private Limited is the Indian subsidiary of IBM, which is headquartered at Bengaluru, Karnataka. It has facilities in Bengaluru, Ahmedabad, Delhi, Kolkata, Mumbai, Chennai, Pune, Gurugram, Noida, Bhubaneshwar, Coimbatore, Visakhapatnam and Hyderabad.

Defunct IBM campuses include the IBM Somers Office Complex (Somers, New York). The company's contributions to industrial architecture and design include works by Eero Saarinen, Ludwig Mies van der Rohe and I.M. Pei. Van der Rohe's building in Chicago, the original center of the company's research division post-World War II, was recognized with the 1990 Honor Award from the National Building Museum.

IBM was recognized as one of the Top 20 Best Workplaces for Commuters by the United States Environmental Protection Agency (EPA) in 2005, which recognized Fortune 500 companies that provided employees with excellent commuter benefits to help reduce traffic and air pollution. In 2004, concerns were raised related to IBM's contribution in its early days to pollution in its original location in Endicott, New York.

Products and services

InterConnect, IBM's annual conference on cloud computing and mobile technologies
 
IBM has a large and diverse portfolio of products and services. As of 2016, these offerings fall into the categories of cloud computing, cognitive computing, commerce, data and analytics, Internet of Things (IoT), IT infrastructure, mobile, and security.

IBM Cloud includes infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service (PaaS) offered through public, private and hybrid cloud delivery models. For instance, the IBM Bluemix PaaS enables developers to quickly create complex websites on a pay-as-you-go model. IBM SoftLayer is a dedicated server, managed hosting and cloud computing provider, which in 2011 reported hosting more than 81,000 servers for more than 26,000 customers. IBM also provides Cloud Data Encryption Services (ICDES), using cryptographic splitting to secure customer data.

IBM also hosts the industry-wide cloud computing and mobile technologies conference InterConnect each year.

Hardware designed by IBM for these categories include IBM's POWER microprocessors, which are employed inside many console gaming systems, including Xbox 360, PlayStation 3, and Nintendo's Wii U. IBM Secure Blue is encryption hardware that can be built into microprocessors, and in 2014, the company revealed TrueNorth, a neuromorphic CMOS integrated circuit and announced a $3 billion investment over the following five years to design a neural chip that mimics the human brain, with 10 billion neurons and 100 trillion synapses, but that uses just 1 kilowatt of power. In 2016, the company launched all-flash arrays designed for small and midsized companies, which includes software for data compression, provisioning, and snapshots across various systems.

IT outsourcing also represents a major service provided by IBM, with more than 40 data centers worldwide. alphaWorks is IBM's source for emerging software technologies, and SPSS is a software package used for statistical analysis. IBM's Kenexa suite provides employment and retention solutions, and includes the BrassRing, an applicant tracking system used by thousands of companies for recruiting. IBM also owns The Weather Company, which provides weather forecasting and includes weather.com and Weather Underground.

Smarter Planet is an initiative that seeks to achieve economic growth, near-term efficiency, sustainable development, and societal progress, targeting opportunities such as smart grids, water management systems, solutions to traffic congestion, and greener buildings.

Services provisions include Redbooks, which are publicly available online books about best practices with IBM products, and developerWorks, a website for software developers and IT professionals with how-to articles and tutorials, as well as software downloads, code samples, discussion forums, podcasts, blogs, wikis, and other resources for developers and technical professionals.

IBM Watson is a technology platform that uses natural language processing and machine learning to reveal insights from large amounts of unstructured data. Watson was debuted in 2011 on the American game-show Jeopardy!, where it competed against champions Ken Jennings and Brad Rutter in a three-game tournament and won. Watson has since been applied to business, healthcare, developers, and universities. For example, IBM has partnered with Memorial Sloan Kettering Cancer Center to assist with considering treatment options for oncology patients and for doing melanoma screenings. Also, several companies have begun using Watson for call centers, either replacing or assisting customer service agents.

In January 2019, IBM introduced its first commercial quantum computer IBM Q System One.

Research

The Thomas J. Watson Research Center in Yorktown Heights, New York, is one of 12 IBM research labs worldwide.
 
Research has been a part of IBM since its founding, and its organized efforts trace their roots back to 1945, when the Watson Scientific Computing Laboratory was founded at Columbia University in New York City, converting a renovated fraternity house on Manhattan's West Side into IBM's first laboratory. Now, IBM Research constitutes the largest industrial research organization in the world, with 12 labs on 6 continents. IBM Research is headquartered at the Thomas J. Watson Research Center in New York, and facilities include the Almaden lab in California, Austin lab in Texas, Australia lab in Melbourne, Brazil lab in São Paulo and Rio de Janeiro, China lab in Beijing and Shanghai, Ireland lab in Dublin, Haifa lab in Israel, India lab in Delhi and Bangalore, Tokyo lab, Zurich lab and Africa lab in Nairobi

In terms of investment, IBM's R&D spend totals several billion dollars each year. In 2012, that expenditure was approximately US$6.9 billion. Recent allocations have included $1 billion to create a business unit for Watson in 2014, and $3 billion to create a next-gen semiconductor along with $4 billion towards growing the company's "strategic imperatives" (cloud, analytics, mobile, security, social) in 2015.

IBM has been a leading proponent of the Open Source Initiative, and began supporting Linux in 1998. The company invests billions of dollars in services and software based on Linux through the IBM Linux Technology Center, which includes over 300 Linux kernel developers. IBM has also released code under different open source licenses, such as the platform-independent software framework Eclipse (worth approximately US$40 million at the time of the donation), the three-sentence International Components for Unicode (ICU) license, and the Java-based relational database management system (RDBMS) Apache Derby. IBM's open source involvement has not been trouble-free, however (see SCO v. IBM). 

Famous inventions and developments by IBM include: the Automated teller machine (ATM), Dynamic random access memory (DRAM), the electronic keypunch, the financial swap, the floppy disk, the hard disk drive, the magnetic stripe card, the relational database, RISC, the SABRE airline reservation system, SQL, the Universal Product Code (UPC) bar code, and the virtual machine. Additionally, in 1990 company scientists used a scanning tunneling microscope to arrange 35 individual xenon atoms to spell out the company acronym, marking the first structure assembled one atom at a time. A major part of IBM research is the generation of patents. Since its first patent for a traffic signaling device, IBM has been one of the world's most prolific patent sources. In 2018, the company holds the record for most patents generated by a business, marking 25 consecutive years for the achievement.

Five IBMers have received the Nobel Prize: Leo Esaki, of the Thomas J. Watson Research Center in Yorktown Heights, N.Y., in 1973, for work in semiconductors; Gerd Binnig and Heinrich Rohrer, of the Zurich Research Center, in 1986, for the scanning tunneling microscope; and Georg Bednorz and Alex Müller, also of Zurich, in 1987, for research in superconductivity. Several IBMers have also won the Turing Award, including the first female recipient Frances E. Allen.

Current research includes a collaboration with the University of Michigan to see computers act as an academic adviser for undergraduate computer science and engineering students at the university, and a partnership with AT&T, combining their cloud and Internet of Things (IoT) platforms to make them interoperable and to provide developers with easier tools.

The company is also involved in research into advanced algorithms and machine learning and their decision-making processes. To that end, the company recently released an analysis tool for how and why algorithms make decisions while scanning for biases in automated decision-making.

Brand and reputation

IBM is nicknamed Big Blue in part due to its blue logo and color scheme, and also partially since IBM once had a de facto dress code of white shirts with blue suits. The company logo has undergone several changes over the years, with its current "8-bar" logo designed in 1972 by graphic designer Paul Rand. It was a general replacement for a 13-bar logo, since period photocopiers did not render large areas well. Aside from the logo, IBM used Helvetica as a corporate typeface for 50 years, until it was replaced in 2017 by the custom-designed IBM Plex

IBM has a valuable brand as a result of over 100 years of operations and marketing campaigns. Since 1996, IBM has been the exclusive technology partner for the Masters Tournament, one of the four major championships in professional golf, with IBM creating the first Masters.org (1996), the first course cam (1998), the first iPhone app with live streaming (2009), and first-ever live 4K Ultra High Definition feed in the United States for a major sporting event (2016). As a result, IBM CEO Ginni Rometty became the third female member of the Master's governing body, the Augusta National Golf Club. IBM is also a major sponsor in professional tennis, with engagements at the U.S. Open, Wimbledon, the Australian Open, and the French Open. The company also sponsored the Olympic Games from 1960–2000, and the National Football League from 2003–2012.

In 2012, IBM's brand was valued at $75.5 billion and ranked by Interbrand as the second-best brand worldwide. That same year, it was also ranked the top company for leaders (Fortune), the number two green company in the U.S. (Newsweek), the second-most respected company (Barron's), the fifth-most admired company (Fortune), the 18th-most innovative company (Fast Company), and the number one in technology consulting and number two in outsourcing (Vault). In 2015, Forbes ranked IBM the fifth-most valuable brand.

People and culture

Employees

IBM has one of the largest workforces in the world, and employees at Big Blue are referred to as "IBMers". The company was among the first corporations to provide group life insurance (1934), survivor benefits (1935), training for women (1935), paid vacations (1937), and training for disabled people (1942). IBM hired its first black salesperson in 1946, and in 1952, CEO Thomas J. Watson, Jr. published the company's first written equal opportunity policy letter, one year before the U.S. Supreme Court decision in Brown vs. Board of Education and 11 years before the Civil Rights Act of 1964. The Human Rights Campaign has rated IBM 100% on its index of gay-friendliness every year since 2003, with IBM providing same-sex partners of its employees with health benefits and an anti-discrimination clause. Additionally, in 2005, IBM became the first major company in the world to commit formally to not use genetic information in employment decisions; and in 2017, IBM was named to Working Mother's 100 Best Companies List for the 32nd consecutive year.

IBM has several leadership development and recognition programs to recognize employee potential and achievements. For early-career high potential employees, IBM sponsors leadership development programs by discipline (e.g., general management (GMLDP), human resources (HRLDP), finance (FLDP)). Each year, the company also selects 500 IBMers for the IBM Corporate Service Corps (CSC), which has been described as the corporate equivalent of the Peace Corps and gives top employees a month to do humanitarian work abroad. For certain interns, IBM also has a program called Extreme Blue that partners top business and technical students to develop high-value technology and compete to present their business case to the company's CEO at internship's end.

The company also has various designations for exceptional individual contributors such as Senior Technical Staff Member (STSM), Research Staff Member (RSM), Distinguished Engineer (DE), and Distinguished Designer (DD). Prolific inventors can also achieve patent plateaus and earn the designation of Master Inventor. The company's most prestigious designation is that of IBM Fellow. Since 1963, the company names a handful of Fellows each year based on technical achievement. Other programs recognize years of service such as the Quarter Century Club established in 1924, and sellers are eligible to join the Hundred Percent Club, composed of IBM salesmen who meet their quotas, convened in Atlantic City, New Jersey. Each year, the company also selects 1,000 IBMers annually to award the Best of IBM Award, which includes an all-expenses paid trip to the awards ceremony in an exotic location. 

IBM's culture has evolved significantly over its century of operations. In its early days, a dark (or gray) suit, white shirt, and a "sincere" tie constituted the public uniform for IBM employees. During IBM's management transformation in the 1990s, CEO Louis V. Gerstner, Jr. relaxed these codes, normalizing the dress and behavior of IBM employees. The company's culture has also given to different plays on the company acronym (IBM), with some saying is stands for "I've Been Moved" due to relocations and layoffs, others saying it stands for "I'm By Myself" pursuant to a prevalent work-from-anywhere norm, and others saying it stands for "I'm Being Mentored" due to the company's open door policy and encouragement for mentoring at all levels. In terms of labor relations, the company has traditionally resisted labor union organizing, although unions represent some IBM workers outside the United States. In Japan, IBM employees also have an American football team complete with pro stadium, cheerleaders and televised games, competing in the Japanese X-League as the "Big Blue".

In 2015, IBM started giving employees the option of choosing either a PC or a Mac as their primary work device, resulting in IBM becoming the world's largest Mac shop. In 2016, IBM eliminated forced rankings and changed its annual performance review system to focus more on frequent feedback, coaching, and skills development.

IBM alumni

Many IBMers have also achieved notability outside of work and after leaving IBM. In business, former IBM employees include Apple Inc. CEO Tim Cook, former EDS CEO and politician Ross Perot, Microsoft chairman John W. Thompson, SAP co-founder Hasso Plattner, Gartner founder Gideon Gartner, Advanced Micro Devices (AMD) CEO Lisa Su, former Citizens Financial Group CEO Ellen Alemany, former Yahoo! chairman Alfred Amoroso, former AT&T CEO C. Michael Armstrong, former Xerox Corporation CEOs David T. Kearns and G. Richard Thoman, former Fair Isaac Corporation CEO Mark N. Greene, Citrix Systems co-founder Ed Iacobucci, ASOS.com chairman Brian McBride, former Lenovo CEO Steve Ward, and former Teradata CEO Kenneth Simonds


Others are NASA astronaut Michael J. Massimino, Canadian astronaut Julie Payette, Harvey Mudd College president Maria Klawe, Western Governors University president emeritus Robert Mendenhall, former University of Kentucky president Lee T. Todd Jr., NFL referee Bill Carollo, former Rangers F.C. chairman John McClelland, and recipient of the Nobel Prize in Literature J. M. Coetzee. Thomas Watson Jr. also served as the 11th national president of the Boy Scouts of America and Tucker Technologies Founder and CEO Mycah E. Tucker

Board and shareholders

The company's 14 member Board of Directors are responsible for overall corporate management and includes the CEOs of American Express, Ford Motor Company, Boeing, Dow Chemical, Johnson and Johnson, and Cemex as well as the president of Rensselaer Polytechnic Institute.

In 2011, IBM became the first technology company Warren Buffett's holding company Berkshire Hathaway invested in. Initially he bought 64 million shares costing 10.5 billion dollars. Over the years he increased his IBM holdings however he reduced it by 94.5% to 2.05 million shares at the end of 2017. By May 2018 he was completely out of IBM.

Bus-size robot set to vacuum up valuable metals from the deep sea

Among metal-rich nodules of the Clarion-Clipperton Zone, a sea anemone–like cnidarian trails 2-meter tentacles.
DIVA AMON AND CRAIG SMITH


Sometimes the sailors' myths aren't far off: The deep ocean really is filled with treasure and creatures most strange. For decades, one treasure—potato-size nodules rich in valuable metals that sit on the dark abyssal floor—has lured big-thinking entrepreneurs, while defying their engineers. But that could change next month with the first deep-sea test of a bus-size machine designed to vacuum up these nodules.

The trial, run by Global Sea Mineral Resources (GSR), a subsidiary of the Belgian dredging giant DEME Group, will take place in the international waters of the Clarion-Clipperton Zone (CCZ), a nodule-rich area the width of the continental United States between Mexico and Hawaii. The Patania II collector, tethered to a ship more than 4 kilometers overhead, will attempt to suck up these nodules through four vacuums as it mows back and forth along a 400-meter-long strip.

Ecologists worried about the effect of the treasure hunt on the fragile deep-sea organisms living among and beyond the nodules should get some answers, too. An independent group of scientists on the German R/V Sonne will accompany GSR's vessel to monitor the effect of the Patania II's traverses. The European-funded effort, called MiningImpact2, will inform regulations under development for seafloor mining, says James Hein, a marine geologist at the U.S. Geological Survey in Santa Cruz, California. "That work is critical."

Since the 1970s, interest in deep-sea mining has waxed and waned with commodity prices. A decade ago, companies were focused on sulfides, copper-rich deposits that form from the mineral-laden hot water gushing from hydrothermal vents. But a plan to mine deposits off Papua New Guinea has met with opposition because the vents are scarce and fragile, and they host unusual life forms. "They are such weird, unique ecosystems," says Andrew Thaler, a deep-sea ecologist who tracks the industry at Blackbeard Biologic, a consultancy in St. Michaels, Maryland. As a result, he says, "It's politically harder to get more mining licenses."

The nodules, however, are abundant, and they are rich in cobalt, a costly metal important for many electronics that is now mined in the forests of the Democratic Republic of the Congo, a conflict zone. If Earth had never been mined and you had to choose between the rainforest or seabed, "you'd absolutely go to the sea floor," Thaler says. "No brainer." The nodules form on deep abyssal plains where sedimentation rates are low, allowing metal compounds dissolved in seawater to encrust a nucleus, like a shark tooth or a rock, over millions of years. Microbes aid the process, especially where they are nourished by nutrients drifting down from life-rich surface waters, says Beth Orcutt, a geomicrobiologist at the Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine.

Ideal for nodule formation, the CCZ is estimated to contain some 27 billion metric tons of the ore. But its abyssal plain is also a garden of exotic life forms. Craig Smith, a benthic ecologist at the University of Hawaii in Honolulu, has helped lead biological surveys in the CCZ that, in one case, revealed 330 species living in just 30 square kilometers, more than two-thirds of them new to science. The CCZ's inhabitants include a giant squid worm, predatory sponges resembling ornamented Christmas trees, green-yellow sea cucumbers that researchers called "gummy squirrels," and a greater variety of bristle worms than ever reported before. "I didn't expect any part of the CCZ to have among the highest diversities of any deep-sea habitat," Smith says. "That caught me by surprise."

Mining could leave a lasting imprint on these ecosystems. In 2015, MiningImpact scientists visited the site of a 1980s experiment off Peru in which a small sledge was pulled along the bottom to simulate nodule harvesting. Three decades later, "It looked like the disturbance had taken place yesterday," says Andrea Koschinsky, a geochemist at Jacobs University in Bremen, Germany, who is working on MiningImpact2. A similar pattern has been seen at small dredging sites in the CCZ. Life in the path of a collector will be lost, says Jens Greinert, a marine geologist at the GEOMAR Helmholtz Centre for Ocean Research in Kiel, Germany, who notes that many filter feeders, such as corals and sponges, live right on the nodules. "They will be sucked up and are gone. You can't go back."

Such concerns make many environmentalists wary of opening any of the deep sea to mining. Some, including United Nations Special Envoy for the Ocean Peter Thomson, are floating the idea of a 10-year "precautionary pause." "It seems like you have these two opposed agendas," says Kirsten Thompson, a marine ecologist at the University of Exeter in the United Kingdom.

GSR declined to comment until after the trial, but other factors are likely to delay commercial operations in the CCZ until late next decade. For one thing, the legal framework for mining in international waters is uncertain. Although the United Nations's International Seabed Authority has granted contracts for exploration, it is still drafting rules that will govern commercial operations and set limits for environmental damage. The rules are unlikely to be final before 2021. For another, the collector, the most advanced mining equipment ever tested at depth, may not work as planned. "When you throw a new piece of technology into the ocean, the ocean tends to throw it right back at you," Thaler says.

To gauge the risk to ecosystems, scientists aboard the Sonne are already patrolling the CCZ, collecting baseline data. Next month, the Sonne will rendezvous with GSR's ship, and over several weeks the two ships, working some 400 meters apart, will conduct the tests in two areas where GSR has exploration contracts from the United Nations. Before each test, the Sonne will spend nearly 3 days sending more than 60 sensors, including radar, sonar, and cameras, down a lift to the sea floor, using a remotely operated vehicle (ROV) to place them. "It's a little bit like playing Tetris," Greinert says.

These sensors will focus on the plume of sediment the collector kicks up. The waters of the CCZ are some of the clearest in the world, and scientists have long feared that mining could spread a vast blanket of silt, hurting life far outside the mining area. Recent experiments, however, suggest most of the silt particles will clump together and fall out within a kilometer or two, Koschinsky says. But a film of finer nanoparticles might spread farther.

As the collector trundles along, the ROV and an autonomous deep-sea robot will follow, capturing close and distant views. At the end of the 400-meter swath, the collector will drop the nodules it harvested in a pile. (This "preprototype" has no system for delivering them to the surface.) The sensors will continue to monitor the plume for 4 days after the work is done.

Although environmentalists might be tempted to condemn any deep-sea mining, even such a small test, GSR should be commended for its willingness to cooperate with the scientists, says Cindy Van Dover, a deep-sea biologist at Duke University in Durham, North Carolina. "I say bravo. We can't get answers until we start doing stuff." Yet given the test's limited scope and the unknowns of deep-sea life, she doubts it will solve what is, to her, the most pressing question: "How will we know we screwed it up?"

A New Ion-Drive Transistor Is Here to Interface With Your Brain


Silicon transistors and the brain don’t mix.

At least not optimally. As scientists and companies are increasingly exploring ways to interface your brain with computers, fashioning new hardware that conforms to and compliments our biological wetware becomes increasingly important.

To be fair, silicon transistors, when made into electrode arrays, can perform the basics: record neural signals, process and analyze them with increasingly sophisticated programs that detect patterns, which in turn can be used to stimulate the brain or control smart prosthetics.

The problem? They’re not biocompatible in the long term. Without modification, implanted electrodes invariably activate the brain’s immune system, resulting in scar tissue around the implantation site as the cells eagerly attack the foreign invader.

The trick is to encase them in plastics that the body tolerates. But if you’ve tried squeezing a sleeve-protective laptop into a small bag, you’ll know that increasing bulk stretches out the bag (my struggle everyday). In the case of brain-machine interfacing electronics, brain tissue is the bag.

To Dr. Dion Khodagholy at Columbia University, the cure isn’t making smaller transistors—we’ve almost hit the limit. Rather, it’s to fabricate entirely new transistors that comfortably interface with human tissue, brain or otherwise. This month, the team described a soft, flexible, and biocompatible transistor that operates on ions, rather than electrons in traditional transistors, in Science Advances.

Because neurons rely on ions for their communication, the new transistors are far more efficient at processing body signals in real time compared to current generation electronics. In a series of tests, the team was able to string multiple transistors together to amplify signals and form logic gates, similar to those used in silicon-based computing.

The devices, made of flexible, biocompatible materials through microfabrication, allowed the team to accurately measure EEG “brain wave” signals without requiring additional adhesives, and lowered the contact space between gadget and scalp by five times compared to the usual setup. If that doesn’t seem particularly impressive, the team has only just begun exploring the potential of their ion-drive transistors.

“Our transistor…makes communication with neural signals of the body more efficient. We’ll now be able to build safer, smaller, and smarter bioelectronic devices, such as brain-machine interfaces, wearable electronics, and responsive therapeutic stimulation devices, that can be implanted in humans over long periods of time,” said Khodagholy.

How Do Transistors Work Anyways?

By making novel transistors, Khodagholy’s team is digging into the very basics of computation—brain or otherwise.

In a nutshell, a transistor is a mini electrical component that does two things very well: one, it works as an amplifier to boost input current, which is what hearing aids or microphones rely on. Two, it works as a switch, allowing a small current to trigger a larger one—this is how computer chips work, with their billions of transistors that can store 0s and 1s and each operating individually.

Silicon transistors, even fancy ones modified for biocompatibility, require ion-to-electron conversion during operation. They act as translators to turn the body’s operating language (ions, a type of charged particle) to one that computers use. Most of them are susceptible to water damage and need to be sequestered inside a protective casing, which introduces bulk and decreases performance.

Scientists have been able to minimize some of those issues with organic electrochemical transistors, which rely on biocompatible molecules linked to each other to form a “channel” that allows signals to flow through with the help of external electrolytes—liquids that conduct electricity. These transistors, however, can’t be individually controlled, making it impossible to build logic gates and circuits, and they’re painfully slow compared to the brain’s operations.

To Khodagholy, an ideal transistor for the brain needs four things: one, it’s built from biocompatible and stable materials; two, it’s soft and flexible to avoid mechanical mismatches with the brain; three, it needs high speed and efficient amplification mechanisms that can tease out and boost useful brain chattering from background noise; and finally, it has to have independent gating, in the sense that each transistor can be controlled separately, which allows them to be linked up into integrated circuits.

Meet the Internal Ion-Gated Organic Electrochemical Transistors (IGTs)

The team’s answer to bio-transistors is the IGT.

In a nutshell, IGTs are built from biocompatible material similar to those previously used. However, they have mobile ions directly embedded into the conducting material that makes up the transistor channel. In this way, they no longer rely on external electrolytes, but are themselves the full package for conducting information.

The secret ingredient? Sugar.

“Sugar molecules attract water molecules and not only help the transistor channel to stay hydrated, but also help the ions travel more easily and quickly within the channel,” Khodagholy explained.

Because the mobile ions are directly in the transistor channels, they don’t have to travel far to modulate the transistor compared to external electrolytes—the typical solution. This makes the IGT respond orders of magnitude faster than electrolyte-gated transistors to changes in external signaling, said study author Dr. George D. Spyropoulos.

Sticking sugar, which provides an ion reservoir, directly into the transistor had another perk: it allowed each transistor to be made independent. Rather than bathing in and sharing external electrolytes, IGTs have the capacity to have their own gates—that is, a membrane that controls whether they’re on or off. In one experiment, the team microfabricated two separate logic gates and confirmed that each operated accurately, performing their intended arithmetic.

This confirms “the scalability of IGT architecture for use as bioelectronics computational modules,” they said.

In another study, the team found that the devices could reliably amplify tiny signals by as much as four-fold. Because neural and other body signals often require multi-stage boosting before they’re accurately picked up and deciphered, IGTs seem perfectly suited for the job.

The No-Fuss EEG

As a proof of concept of IGT’s biocompatibility, the team turned its focus on EEG. Widely used in clinics and labs, EEG picks up brain waves using a cap of electrodes on the surface of the scalp.

It’s not a fun process: the scalp often has to be exfoliated (ouch!) and an adhesive is used to better stick on the metal electrodes, which causes irritation at best and rashes at worst. Hair also gets in the way and muddies signals.

IGT, in contrast, is a dream. Its small size meant that the team could slip it between hair follicles. Its flexibility and bendiness made it possible to slap it straight onto the scalp—no pretreatments required. In a test that measures brain signals when people are awake with their eyes closed, IGTs reliably and consistently picked up the brain’s activity.

A portable, lightweight EEG device that can be manipulated by hand could already change the future of neurology. But that’s just the beginning. The tiny size of IGTs means it will be possible to apply more devices to smaller areas to measure signals at a finer scale, or stick them into areas normally too small or irregular to accommodate electrodes. Because they’re intrinsically soft, conformable, and biocompatible, they can be used on extremely delicate tissue, such as a newborn’s scalp or inside the brain.

But most importantly, said study author Dr. Jennifer Gelinas, IGTs can perform circuit computations. This means they could one day be part of a closed-loop system capable of detecting the brain’s electrical patterns and stimulate accordingly, with far less risk than current electrode-based interfaces.

“With such speed and amplification, combined with their ease of microfabrication, these transistors could be applied to many different types of devices. There is great potential for the use of these devices to benefit patient care in the future,” said Khodagholy.

Mainframe computer

From Wikipedia, the free encyclopedia

A pair of IBM mainframes. On the left is the IBM z Systems z13. On the right is the IBM LinuxONE Rockhopper.
 
An IBM System z9 mainframe
 
Mainframe computers or mainframes (colloquially referred to as "big iron") are computers used primarily by large organizations for critical applications; bulk data processing, such as census, industry and consumer statistics, enterprise resource planning; and transaction processing. They are larger and have more processing power than some other classes of computers: minicomputers, servers, workstations, and personal computers

The term originally referred to the large cabinets called "main frames" that housed the central processing unit and main memory of early computers. Later, the term was used to distinguish high-end commercial machines from less powerful units. Most large-scale computer system architectures were established in the 1960s, but continue to evolve. Mainframe computers are often used as servers.

Design

Modern mainframe design is characterized less by raw computational speed and more by:
  • Redundant internal engineering resulting in high reliability and security
  • Extensive input-output ("I/O") facilities with the ability to offload to separate engines
  • Strict backward compatibility with older software
  • High hardware and computational utilization rates through virtualization to support massive throughput.
  • Hot-swapping of hardware, such as processors and memory.
Their high stability and reliability enable these machines to run uninterrupted for very long periods of time, with mean time between failures (MTBF) measured in decades. 

Mainframes have high availability, one of the primary reasons for their longevity, since they are typically used in applications where downtime would be costly or catastrophic. The term reliability, availability and serviceability (RAS) is a defining characteristic of mainframe computers. Proper planning and implementation is required to realize these features. In addition, mainframes are more secure than other computer types: the NIST vulnerabilities database, US-CERT, rates traditional mainframes such as IBM Z (previously called z Systems, System z and zSeries), Unisys Dorado and Unisys Libra as among the most secure with vulnerabilities in the low single digits as compared with thousands for Windows, UNIX, and Linux. Software upgrades usually require setting up the operating system or portions thereof, and are non-disruptive only when using virtualizing facilities such as IBM z/OS and Parallel Sysplex, or Unisys XPCL, which support workload sharing so that one system can take over another's application while it is being refreshed. 

In the late 1950s, mainframes had only a rudimentary interactive interface (the console), and used sets of punched cards, paper tape, or magnetic tape to transfer data and programs. They operated in batch mode to support back office functions such as payroll and customer billing, most of which were based on repeated tape-based sorting and merging operations followed by line printing to preprinted continuous stationery. When interactive user terminals were introduced, they were used almost exclusively for applications (e.g. airline booking) rather than program development. Typewriter and Teletype devices were common control consoles for system operators through the early 1970s, although ultimately supplanted by keyboard/display devices. 

By the early 1970s, many mainframes acquired interactive user terminals operating as timesharing computers, supporting hundreds of users simultaneously along with batch processing. Users gained access through keyboard/typewriter terminals and specialized text terminal CRT displays with integral keyboards, or later from personal computers equipped with terminal emulation software. By the 1980s, many mainframes supported graphic display terminals, and terminal emulation, but not graphical user interfaces. This form of end-user computing became obsolete in the 1990s due to the advent of personal computers provided with GUIs. After 2000, modern mainframes partially or entirely phased out classic "green screen" and color display terminal access for end-users in favour of Web-style user interfaces.

The infrastructure requirements were drastically reduced during the mid-1990s, when CMOS mainframe designs replaced the older bipolar technology. IBM claimed that its newer mainframes reduced data center energy costs for power and cooling, and reduced physical space requirements compared to server farms.

Characteristics

Inside an IBM System z9 mainframe
 
Modern mainframes can run multiple different instances of operating systems at the same time. This technique of virtual machines allows applications to run as if they were on physically distinct computers. In this role, a single mainframe can replace higher-functioning hardware services available to conventional servers. While mainframes pioneered this capability, virtualization is now available on most families of computer systems, though not always to the same degree or level of sophistication.

Mainframes can add or hot swap system capacity without disrupting system function, with specificity and granularity to a level of sophistication not usually available with most server solutions. Modern mainframes, notably the IBM zSeries, System z9 and System z10 servers, offer two levels of virtualization: logical partitions (LPARs, via the PR/SM facility) and virtual machines (via the z/VM operating system). Many mainframe customers run two machines: one in their primary data center, and one in their backup data center—fully active, partially active, or on standby—in case there is a catastrophe affecting the first building. Test, development, training, and production workload for applications and databases can run on a single machine, except for extremely large demands where the capacity of one machine might be limiting. Such a two-mainframe installation can support continuous business service, avoiding both planned and unplanned outages. In practice many customers use multiple mainframes linked either by Parallel Sysplex and shared DASD (in IBM's case), or with shared, geographically dispersed storage provided by EMC or Hitachi.

Mainframes are designed to handle very high volume input and output (I/O) and emphasize throughput computing. Since the late-1950s, mainframe designs have included subsidiary hardware (called channels or peripheral processors) which manage the I/O devices, leaving the CPU free to deal only with high-speed memory. It is common in mainframe shops to deal with massive databases and files. Gigabyte to terabyte-size record files are not unusual. Compared to a typical PC, mainframes commonly have hundreds to thousands of times as much data storage online, and can access it reasonably quickly. Other server families also offload I/O processing and emphasize throughput computing. 

Mainframe return on investment (ROI), like any other computing platform, is dependent on its ability to scale, support mixed workloads, reduce labor costs, deliver uninterrupted service for critical business applications, and several other risk-adjusted cost factors. 

Mainframes also have execution integrity characteristics for fault tolerant computing. For example, z900, z990, System z9, and System z10 servers effectively execute result-oriented instructions twice, compare results, arbitrate between any differences (through instruction retry and failure isolation), then shift workloads "in flight" to functioning processors, including spares, without any impact to operating systems, applications, or users. This hardware-level feature, also found in HP's NonStop systems, is known as lock-stepping, because both processors take their "steps" (i.e. instructions) together. Not all applications absolutely need the assured integrity that these systems provide, but many do, such as financial transaction processing.

Current market

IBM, with z Systems, continues to be a major manufacturer in the mainframe market. Unisys manufactures ClearPath Libra mainframes, based on earlier Burroughs MCP products and ClearPath Dorado mainframes based on Sperry Univac OS 1100 product lines. In 2000, Hitachi co-developed the zSeries z900 with IBM to share expenses, but subsequently the two companies have not collaborated on new Hitachi models. Hewlett-Packard sells its unique NonStop systems, which it acquired with Tandem Computers and which some analysts classify as mainframes. Groupe Bull's GCOS, Fujitsu (formerly Siemens) BS2000, and Fujitsu-ICL VME mainframes are still available in Europe, and Fujitsu (formerly Amdahl) GS21 mainframes globally. NEC with ACOS and Hitachi with AP10000-VOS3 still maintain mainframe hardware businesses in the Japanese market. 

The amount of vendor investment in mainframe development varies with market share. Fujitsu and Hitachi both continue to use custom S/390-compatible processors, as well as other CPUs (including POWER and Xeon) for lower-end systems. Bull uses a mixture of Itanium and Xeon processors. NEC uses Xeon processors for its low-end ACOS-2 line, but develops the custom NOAH-6 processor for its high-end ACOS-4 series. IBM continues to pursue a different business strategy of mainframe investment and growth. IBM has its own large research and development organization designing new, homegrown CPUs, including mainframe processors such as 2012's 5.5 GHz six-core zEC12 mainframe microprocessor. Unisys produces code compatible mainframe systems that range from laptops to cabinet-sized mainframes that utilize homegrown CPUs as well as Xeon processors. IBM is rapidly expanding its software business, including its mainframe software portfolio, to seek additional revenue and profits.

Furthermore, there exists a market for software applications to manage the performance of mainframe implementations. In addition to IBM, significant players in this market include BMC, Compuware, and CA Technologies.

History

An IBM 704 mainframe (1964)
 
Several manufacturers produced mainframe computers from the late 1950s through the 1970s. The US group of manufacturers was first known as "IBM and the Seven Dwarfs": usually Burroughs, UNIVAC, NCR, Control Data, Honeywell, General Electric and RCA, although some lists varied. Later, with the departure of General Electric and RCA, it was referred to as IBM and the BUNCH. IBM's dominance grew out of their 700/7000 series and, later, the development of the 360 series mainframes. The latter architecture has continued to evolve into their current zSeries mainframes which, along with the then Burroughs and Sperry (now Unisys) MCP-based and OS1100 mainframes, are among the few mainframe architectures still extant that can trace their roots to this early period. While IBM's zSeries can still run 24-bit System/360 code, the 64-bit zSeries and System z9 CMOS servers have nothing physically in common with the older systems. Notable manufacturers outside the US were Siemens and Telefunken in Germany, ICL in the United Kingdom, Olivetti in Italy, and Fujitsu, Hitachi, Oki, and NEC in Japan. The Soviet Union and Warsaw Pact countries manufactured close copies of IBM mainframes during the Cold War; the BESM series and Strela are examples of an independently designed Soviet computer. 

Shrinking demand and tough competition started a shakeout in the market in the early 1970s—RCA sold out to UNIVAC and GE sold its business to Honeywell; in the 1980s Honeywell was bought out by Bull; UNIVAC became a division of Sperry, which later merged with Burroughs to form Unisys Corporation in 1986. 

During the 1980s, minicomputer-based systems grew more sophisticated and were able to displace the lower-end of the mainframes. These computers, sometimes called departmental computers were typified by the DEC VAX

In 1991, AT&T Corporation briefly owned NCR. During the same period, companies found that servers based on microcomputer designs could be deployed at a fraction of the acquisition price and offer local users much greater control over their own systems given the IT policies and practices at that time. Terminals used for interacting with mainframe systems were gradually replaced by personal computers. Consequently, demand plummeted and new mainframe installations were restricted mainly to financial services and government. In the early 1990s, there was a rough consensus among industry analysts that the mainframe was a dying market as mainframe platforms were increasingly replaced by personal computer networks. InfoWorld's Stewart Alsop infamously predicted that the last mainframe would be unplugged in 1996; in 1993, he cited Cheryl Currid, a computer industry analyst as saying that the last mainframe "will stop working on December 31, 1999", a reference to the anticipated Year 2000 problem (Y2K). 

That trend started to turn around in the late 1990s as corporations found new uses for their existing mainframes and as the price of data networking collapsed in most parts of the world, encouraging trends toward more centralized computing. The growth of e-business also dramatically increased the number of back-end transactions processed by mainframe software as well as the size and throughput of databases. Batch processing, such as billing, became even more important (and larger) with the growth of e-business, and mainframes are particularly adept at large-scale batch computing. Another factor currently increasing mainframe use is the development of the Linux operating system, which arrived on IBM mainframe systems in 1999 and is typically run in scores or up to ~ 8,000 virtual machines on a single mainframe. Linux allows users to take advantage of open source software combined with mainframe hardware RAS. Rapid expansion and development in emerging markets, particularly People's Republic of China, is also spurring major mainframe investments to solve exceptionally difficult computing problems, e.g. providing unified, extremely high volume online transaction processing databases for 1 billion consumers across multiple industries (banking, insurance, credit reporting, government services, etc.) In late 2000, IBM introduced 64-bit z/Architecture, acquired numerous software companies such as Cognos and introduced those software products to the mainframe. IBM's quarterly and annual reports in the 2000s usually reported increasing mainframe revenues and capacity shipments. However, IBM's mainframe hardware business has not been immune to the recent overall downturn in the server hardware market or to model cycle effects. For example, in the 4th quarter of 2009, IBM's System z hardware revenues decreased by 27% year over year. But MIPS (millions of instructions per second) shipments increased 4% per year over the past two years. Alsop had himself photographed in 2000, symbolically eating his own words ("death of the mainframe").

In 2012, NASA powered down its last mainframe, an IBM System z9. However, IBM's successor to the z9, the z10, led a New York Times reporter to state four years earlier that "mainframe technology — hardware, software and services — remains a large and lucrative business for I.B.M., and mainframes are still the back-office engines behind the world’s financial markets and much of global commerce". As of 2010, while mainframe technology represented less than 3% of IBM's revenues, it "continue[d] to play an outsized role in Big Blue's results".

In 2015, IBM launched the IBM z13 and on June 2017 the IBM z14.

Differences from supercomputers

A supercomputer is a computer at the leading edge of data processing capability, with respect to calculation speed. Supercomputers are used for scientific and engineering problems (high-performance computing) which crunch numbers and data, while mainframes focus on transaction processing. The differences are:
  • Mainframes are built to be reliable for transaction processing (measured by TPC-metrics; not used or helpful for most supercomputing applications) as it is commonly understood in the business world: the commercial exchange of goods, services, or money. A typical transaction, as defined by the Transaction Processing Performance Council, updates a database system for inventory control (goods), airline reservations (services), or banking (money) by adding a record. A transaction may refer to a set of operations including disk read/writes, operating system calls, or some form of data transfer from one subsystem to another which is not measured by the processing speed of the cpu. Transaction processing is not exclusive to mainframes but is also used by microprocessor-based servers and online networks.
  • Supercomputer performance is measured in floating point operations per second (FLOPS) or in traversed edges per second or TEPS, metrics that are not very meaningful for mainframe applications, while mainframes are sometimes measured in millions of instructions per second (MIPS), although the definition depends on the instruction mix measured. Examples of integer operations measured by MIPS include adding numbers together, checking values or moving data around in memory (while moving information to and from storage, so-called I/O is most helpful for mainframes; and within memory, only helping indirectly). Floating point operations are mostly addition, subtraction, and multiplication (of binary floating point in supercomputers; measured by FLOPS) with enough digits of precision to model continuous phenomena such as weather prediction and nuclear simulations (only recently standardized decimal floating point, not used in supercomputers, are appropriate for monetary values such as those useful for mainframe applications). In terms of computational speed, supercomputers are more powerful.
In 2007, an amalgamation of the different technologies and architectures for supercomputers and mainframes has led to the so-called gameframe.
