Questions tagged [sgi]

Silicon Graphics Inc. was a computer hardware and software manufacturer known for its high-end workstations, the IRIX OS and an early implementation of the STL

SGI produced workstations often used for 3D graphics and also produced its own version of UNIX SysV called IRIX. Use the tag for questions about IRIX.

SGI is also known for producing one of the first implementations of the C++ Standard Template Library. Questions about that should use the tag unless they are specific to the SGI implementation.

SGI filed for bankruptcy in 2009, and the company that bought most of its the assets, Rackable System, was later renamed to Silicon Graphics International. See the Wikipedia page for more information.
