Hopper Cray XE6
Hopper Status: Up
Hopper is NERSC's first peta-flop system, a Cray XE6, with a peak performance of 1.28 Petaflops/sec, 153,216 compute cores, 217 Terabytes of memory, and 2 Petabytes of disk. Hopper placed number 5 on the November 2010 Top500 Supercomputer list.
Astrophysicists using NERSC's Hopper system generated a 3D trillion-particle magnetic reconnection dataset, where each time-step amounted to a massive 32 terabyte file. With specialized tools developed by Berkeley Lab researchers, the scientists queried the dataset in 3 seconds and visualized it. This is the first-time a dataset of this magnitude has been queried and visualized so quickly. Read More »
