Sequent Computer Systems was a computer company that designed and manufactured multiprocessing computer systems. They were among the pioneers in high-performance symmetric multiprocessing (SMP) open systems, innovating in both hardware (e.g. cache management and interrupt handling) and software (e.g. read-copy-update). Through a partnership with Oracle Corporation, Sequent became a dominant high-end UNIX platform in the late 1980s and early 1990s. Later they introduced a next-generation high-end platform for UNIX and Windows NT based on a non-uniform memory access architecture, NUMA-Q. As hardware prices fell in the late 1990s, and Intel shifted their server focus to the Itanium processor family, Sequent joined the Project Monterey effort in October 1998. which aimed to move a standard Unix to several new platforms.〔(Sequent was overmatched, CEO says ), a July 1999 article from CNET Networks〕 In July 1999 Sequent agreed to be acquired by IBM.〔(Sequent Computer Systems To Be Acquired by I.B.M. ), a July 13, 1999 article from ''The New York Times''〕 At the time, Sequent's CEO said its technology would "find its way through IBM's entire product field"〔 and IBM announced it would "both sell Sequent machines, and fold Sequent's technology...into its own servers",〔 but by May 2002 a decline in sales of the models acquired from Sequent, among other reasons, led to the retirement of Sequent-heritage products.〔(IBM lays off 250 in Beaverton ), a May 2002 article from ''Portland Business Journal'', one of the American City Business Journals〕 Vestiges of Sequent's innovations live on in the form of data clustering software from PolyServe, various projects within OSDL, IBM contributions to the Linux kernel, and claims in the SCO v. IBM lawsuit.〔''e.g.'' (), (), (), (), ()〕 == History == Originally named Sequel,〔(Advanced Architecture Computers ) and (Part Two ), Argonne National Labs, Technical Report No. 57, Jack J. Dongarra and Iain S. Duff〕 Sequent was formed in 1983 when a group of seventeen engineers and executives left Intel after the failed iAPX 432 "mainframe on a chip" project was cancelled; they were joined by one non-Intel employee. They started Sequent to develop a line of SMP computers, then considered one of the up-and-coming fields in computer design. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sequent Computer Systems」の詳細全文を読む スポンサード リンク
