NERSCPowering Scientific Discovery Since 1974

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. 

Simulations Reveal Unusual Death for Ancient Stars

Those primordial stars—between 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died unusually. In death, these objects—among the Universe’s first-generation of stars—would have exploded as supernovae and burned completely, leaving no remnant black hole behind. Read More »

Water and Gold: A Promising Mix for Future Batteries

For the first time, researchers at Lawrence Berkeley National Laboratory have observed the molecular structure of liquid water at a gold surface under different charging conditions, paving the way for future studies of electrochemical interfaces that exist in current and prototype batteries. Calculations run at NERSC helped them better understand the chemistry. Read More »

BOSS Measures the Universe to One-Percent Accuracy

January 8, 2014 | Tags: Carver, Hopper, HPSS

The Baryon Oscillation Spectroscopic Survey announced that it has measured the scale of the universe’s structure to an accuracy of one percent. This and future measurements at this precision are the key to determining the nature of dark energy. Read More »
