Discover

The Discover system is an assembly of multiple Linux scalable units built upon commodity components. The first scalable unit was installed in the fall of 2006, and the NCCS continues to expand this highly successful computing platform.

Discover derives its name from the NASA adage of "Explore. Discover. Understand."
