SGI

From TOP500 Supercomputing Sites - Wiki

Silicon Graphics, Inc., commonly called SGI, began as a maker of graphics display terminals in 1982. It was founded by Jim Clark and Abbey Silverstone.

SGI's core market has traditionally been Hollywood special effects studios. In fact, SGI's largest markets in terms of dollars of revenue generated have always been government and defense applications, energy, and scientific and technical computing.

SGI created the proprietary 3D graphics API Iris GL, from which the cross-platform OpenGL was developed by a consortium of companies.

In recent years, SGI has continued to enhance its line of servers (of which the higher-end models are actually supercomputers) based around the Scalable Node architecture.
