NERSCPowering Scientific Discovery Since 1974

NERSC Global Filesystem

NGF is a collection of centerwide file systems, based on IBM’s GPFS, available on nearly all systems at the facility.  The several different file systems that comprise NGF include: one providing a common login user environment for all our systems, one for sharing data among collaborators on a science project or team, and one for high bandwidth short term storage across systems at the facility.  The main focus of NGF is data sharing, ease of workflow management (i.e., not moving data around or maintaining unnecessary copies of data), and data analysis.

Global Scratch Gets an Upgrade

October 29, 2013

The most used file system at the National Energy Research Scientific Computing Center (NERSC)—global scratch—just got an upgrade. As a result, some users may see their data output to global scratch reach up to 80 gigabytes per second. Read More »

NERSC Global Filesystem Played a Key Role in Discovery of the Last Neutrino Mixing Angle

Discovery of the last neutrino mixing angle was announced in March 2012, just a few months after the Daya Bay Neutrino Experiment’s first detectors went online in southeast China. But that result might not have been available so quickly without the NERSC Global Filesystem (NGF) infrastructure, which allowed staff at the U.S. Department of Energy’s (DOE’s) NERSC to rapidly scale up disk and node resources to accommodate the surprisingly large influx of data.
