Altix

Altix

Altix is Silicon Graphics' line of servers and supercomputers. The line was first announced in January 2003, with the Altix 3000 offering Intel Itanium 2 processor setups running Red Hat Enterprise Linux or SUSE with SGI ProPack. The systems could originally support up to 64 processors. SGI announced 128-processor systems in February 2004, and delivered 256- and 512-processor systems later in 2004. SGI later produced the Altix 4000 series based on a newer Itanium 2, and the Altix XE series based on Intel dual and quad-core Xeon processors.

NASA's Columbia supercomputer, installed in 2004, is based on the Altix architecture and features 10,240 processors. It is built from twenty Altix systems interconnected with Infiniband.
