NERSCPowering Scientific Discovery Since 1974


Cori Status: Up

Cori, a Cray XC40, has a peak performance of about 30 petaflops and is NERSC's newest supercomputer. The system is named in  honor of American biochemist Gerty Cori, the first American woman to win a Nobel Prize in science and the first woman ever to win a  Nobel Prize for Physiology or Medicine. Cori is comprised of 2,388 Intel Xeon "Haswell" processor nodes, 9,688 Intel Xeon Phi "Knight's Landing" nodes, and a 1.8 PB Cray Data Warp Burst Buffer.

A TOAST for Next Generation CMB Experiments

September 19, 2017

Computational cosmologists at Berkeley Lab they recently achieved a critical milestone in preparation for upcoming CMB experiments: scaling their data simulation and reduction framework TOAST to run on all 658,784 Intel Knights Landing Xeon Phi processor cores on the NERSC’s Cori. The team also implemented a new TOAST module to simulate the noise introduced when ground-based telescopes look at the CMB through the atmosphere. Read More »
