The centerpiece of the NCCS is the 90,000-core “Discover” supercomputing cluster, an assembly of multiple Linux scalable units built upon commodity components capable of nearly 3.5 petaflops, or 3,500 trillion floating-point operations per second.
Discover is particularly suited for large, complex, communications-intensive problems employing large matrices and science applications, which benefit from its ecosystem of system software and tools. Example applications include fine-scale, high-fidelity simulations of the atmosphere and oceans that span time scales from days (weather prediction), to seasons and years (short-term climate prediction), to decades and centuries (climate change projection).
Discover derives its name from the NASA adage of "Explore. Discover. Understand.” The NCCS installed the first scalable unit in the fall of 2006 and continues to expand this highly successful computing platform.
