Blue Waters system stats |
|
|
Blue Waters is designed to meet the compute-intensive, memory-intensive, and data-intensive needs of a wide range of scientists and engineers. It will deliver sustained performance of one petaflop (one quadrillion calculations per second). The Blue Waters team will demonstrate sustained-petascale performance using eight scientific applications—codes used in everything from earthquake prediction to the study of how a virus enters a cell to modeling severe storms and climate change.
