NERSC and HDF Group Optimize HDF5 Library to Improve I/O Performance

June 28, 2010

A common complaint among air travelers on short trips is that the time it takes to get in and out of the airplane and airports can be as long as the flight itself. In computer terms, that's a classic input/output (I/O) problem. Supercomputer users sometimes face a similar problem: the computer tears through the calculations with amazing speed, but the time it takes to write the resulting data to disk ends up slowing down the whole job. There are several layers of software that deal with… Read More »

Grace Hopper Powers Science on NERSC's New Cray XE6

June 4, 2010

NERSC's new flagship petascale supercomputer will be named "Hopper" in honor of American computer scientist Grace Hopper. A pioneer in the field of software development and programming languages, Hopper created the first compiler. She was a champion for increasing the usability of computers, understanding that their power and reach would be limited unless they were made to be more user-friendly. Read More »

Historic Sudbury Neutrino Observatory Data, Carried by ESnet, Lives on at NERSC

January 26, 2010 | Tags: Astrophysics

Tunneled 6,800 feet underground in Canada's Vale Inco Creighton mine, the Sudbury Neutrino Observatory (SNO) was designed to detect neutrinos produced by fusion reactions in the Sun. Although the observatory officially "switched off" in August 2006, a copy of all the data generated for and by the experiment will live on at the National Energy Research Scientific Computing Center (NERSC).
