- Thinking Machines
Thinking Machines Corporation was a
supercomputer manufacturer founded inWaltham, Massachusetts in 1982 by W. Daniel "Danny" Hillis andSheryl Handler to turn Hillis's doctoral work atMIT on massively parallel computing architectures into a commercial product called theConnection Machine . The company moved in 1984 from Waltham toKendall Square inCambridge, Massachusetts , close to theMIT AI Lab and Thinking Machines' competitorKendall Square Research . Besides Kendall Square Research, Thinking Machines' competitors includedMasPar , which made a computer similar to the CM-2, and Meiko, whose CS-2 was similar to the CM-5. The company filed for bankruptcy in 1994, with its hardware and parallel computing software divisions eventually acquired bySun Microsystems .:"We're building a machine that will be proud of us." – Thinking Machines' motto
Products
Thinking Machines produced a number of Connection Machine models (in chronological order): the CM-1, CM-2, CM-200, CM-5, and the CM-5E. The CM-1 and 2 came first in models with 64K (65,536) bit-serial processors (16 processors per chip) and later smaller numbered versions (16,384 (16K) and 4,096 (4K) processors). The Connection Machine was programmed in a variety of specialized languages, including
*Lisp and CM Lisp (derived fromCommon Lisp ),C* (derived from C), and CMFORTRAN (using a special compiler to translate standard Fortran code to the parallel instruction set of the machine). The CM-1 through CM-200 were examples ofSIMD architecture (Single Instruction Multiple Data), while the later CM-5 and CM-5E wereMIMD (Multiple Instructions Multiple Data) using commoditySPARC processors using a "fat tree " interconnect. Thinking Machines also introduced the first commercialRAID disk array, called theDataVault , in 1985.The CM-2 required a
Symbolics 3600 LISP machines as afront-end processor; later models usedSun Microsystems workstations orVAX minicomputers.Thinking Machines developed the C* programming language as an extension of the C programming language for the Connection Machine data parallel computing system.
Business history
Thinking Machines became profitable in 1989 thanks to its
DARPA contracts,Fact|date=March 2008 and in 1990 the company had $65 million (USD) in revenue, making it the market leader in parallel supercomputers. In 1991, DARPA reduced its purchases amid criticism it was unfairly subsidizing Thinking Machines at the expense of other vendors likeCray ,IBM , and in particular,NCUBE andMasPar . By 1992 the company was losing money again, due to lack of business; CEOSheryl Handler was forced out in the face of public criticism.Thinking Machines filed for
Chapter 11 bankruptcy in August 1994. The hardware portion of the company was purchased bySun Microsystems , and TMC re-emerged as a small software company specializing in parallel software tools for commodity clusters anddata mining software for its installed base and former competitors' parallel supercomputers. In December 1996, the parallel software development business was acquired bySun Microsystems , forming the basis of Sun's entry intoHigh Performance Computing .Thinking Machines continued as a pure data mining company until it was acquired in 1999 by
Oracle Corporation .The program WAIS, developed at Thinking Machines by
Brewster Kahle , would later be influential in starting theInternet Archive and associated projects including theRosetta Disk as part of Danny Hillis' Clock of the Long Now.Key architect
Greg Papadopoulos later became Sun Microsystems, Inc.'s Chief Technology Officer.Dispersal
Many of the hardware people left for
Sun Microsystems and went on to design theSun Enterprise series of parallel computers. TheDarwin datamining toolkit , developed by Thinking Machines' Business Supercomputer Group, was purchased by Oracle. Most of the team that built "Darwin" left forDun & Bradstreet soon after the company entered bankruptcy.Thinking Machines alumni ("thunkos") were instrumental in forming several parallel computing software start-ups, including
Ab Initio Software and Applied Parallel Technologies.Ab Initio is still an independent company; Applied Parallel Technologies, later renamed toTorrent Systems , was acquired byAscential Software , which was in turn acquired byIBM .Besides Danny Hillis, other noted people who worked for or with the company included
Greg Papadopoulos ,David Waltz ,Guy L Steele, Jr. ,Karl Sims ,Brewster Kahle ,Bradley Kuszmaul ,Charles E. Leiserson ,Marvin Minsky ,Carl Feynman ,Cliff Lasser ,Alex Vasilevsky ,Doug Lenat ,Stephen Wolfram ,Eric Lander ,Richard Feynman ,Mirza Mehdi ,Alan Harshman ,Alan Mercer , James Bailey,Tsutomu Shimomura [http://www.takedown.com/bio/tsutomu.html] andJack Schwartz .DARPA 's Connection Machines were decommissioned by 1996.
