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.
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.
