NERSCPowering Scientific Discovery Since 1974

MAJORANA DEMONSTRATOR

A new underground neutrino experiment could provide greater clarity on matter-antimatter imbalance in the Cosmos. And NERSC will be the principal site for data processing and analyses throughout the course of the experiment. » Read More

A Reference Catalog for the Rumen Microbiome

Using supercomputers at NERSC, an international research team has created a reference catalog for the rumen mmicrobiome. Rumen microbes play a vital role in allowing ruminant (cud-chewing) livestock to break down food, and produce milk, meat and wool, which help support the livelihoods and food security of over a billion people worldwide. » Read More

Metagenomic Clustering Powered by Supercomputers

Berkeley Lab and JGI researchers took one of the most popular clustering approaches in modern biology—Markov Clustering algorithm—and modified it to run efficiently and at scale on supercomputers at NERSC. » Read More

Searching for Strongly Lensed Supernovae

Using NERSC supercomputers, astrophysicists at Berkeley Lab and the University of Portsmouth discovered how to control the effects of "micolensing." Armed with this knowledge they believe they will be able to find 1000 strongly lensed Type Ia supernovae in real-time from LSST data--that's 20 times more than previous expectations. » Read More

'Bubbles' the Cray-2

In 1985, NERSC was the first to install the Cray-2, then the fastest computer in the world. Today, an iPad has more processing power. The Cray-2 was nicknamed "Bubbles" for its unique liquid cooling system.
