Altix is Silicon Graphics' line of Intel Itanium based servers and supercomputers. The line was first announced in January 2003, with the Altix 3000 offering Intel Itanium 2 processor setups running Linux. The systems could originally support up to 64 processors. SGI announced 128-processor systems in February 2004, and 256- and 512-processor systems are now available as well.

NASA's new Columbia (supercomputer) is based on the Altix architecture and features 10,240 processors. It is built from twenty Altix systems interconnected with infiniband.
