Altix was a line of server computers and supercomputers produced by Silicon Graphics (and successor company Silicon Graphics International), based on Intel processors. It succeeded the MIPS/IRIX-based Origin 3000 servers. ==History== The line was first announced on January 7, 2003, with the Altix 3000 series, based on Intel Itanium 2 processors and SGI's NUMAlink processor interconnect. At product introduction, the system supported up to 64 processors running Linux as a single system image and shipped with a Linux distribution called SGI Advanced Linux Environment, which was compatible with Red Hat Advanced Server. By August 2003, many SGI Altix customers were running Linux on 128- and even 256-processor SGI Altix systems.〔(SGI aims high with Altix machine - CNET News )〕 SGI officially announced 256-processor support within a single system image of Linux on March 10, 2004 using a 2.4-based Linux kernel. The SGI Advanced Linux Environment was eventually dropped after support using a standard, unmodified SUSE Linux Enterprise Server (SLES) distribution for SGI Altix was provided with SLES 8〔(Altix® 3700 )〕 and SLES 9.〔 Later, SGI Altix 512-processor systems were officially supported〔(Altix 3700 512p )〕 using an unmodified, standard Linux distribution with the launch of SLES 9 SP1. Besides full support of SGI Altix on SUSE Linux Enterprise Server, a standard and unmodified Red Hat Enterprise Linux was also fully supported starting with SGI Altix 3700 Bx2 with RHEL 4〔(Certification - Altix 3700 Bx2 )〕 and RHEL 5〔(Certification - Altix 3700 bx2 )〕 with system processor limits defined by Red Hat for those releases. On November 14, 2005, SGI introduced the Altix 4000 series based on the Itanium 2.〔Silicon Graphics, Inc. (14 November 2005). ''SGI Launches New Flagship Altix 4000 Platform''. (Press release).〕 The Altix 3000 and 4000 are distributed shared memory multiprocessors. SGI later officially supported 1024-processor systems on an unmodified, standard Linux distribution with the launch of SLES 10〔(SGI® Altix® 4700 )〕 in July 2006. SGI Altix 4700 was also officially supported by Red Hat with RHEL 4〔(Certification - Altix 4700 )〕 and RHEL 5〔(Certification - Altix 4700 )〕 — maximum processor limits were as defined by Red Hat for its RHEL releases. The Altix brand was used for systems based on multi-core Intel Xeon processors. These include the Altix XE rackmount servers, Altix ICE blade servers and Altix UV supercomputers. NASA's Columbia supercomputer, installed in 2004 and decommissioned in 2013, was a 10240-microprocessor cluster of twenty Altix 3000 systems, each with 512 microprocessors, interconnected with InfiniBand. 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「Altix」の詳細全文を読む スポンサード リンク
