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. 

Taming Plasma Fusion Snakes

Controlled nuclear fusion has held the promise of a safe, clean, sustainable energy resource for decades. Now, with concerns over global climate change growing, the ability to produce a reliable carbon-free energy source has taken on new urgency. 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 »

New Model of Earth’s Interior Reveals Clues to Hotspot Volcanoes

October 29, 2013 | Tags: Basic Energy Sciences (BES), Geosciences, Hopper

Using supercomputers at NERSC, scientists have detected previously unknown channels of slow-moving seismic waves in Earth’s upper mantle. This discovery helps to explain how “hotspot volcanoes”—the kind that give birth to island chains like Hawaii and Tahiti—come to exist. Read More »
