Grid Computing at NERSC

Grid copmputing can include a broad range of technologies. At NERSC we are primarily interested in new computinational and data-centric services which enhance the productivity of science teams. The grid infrastrcuture we support (described below) can be used to manage jobs and data in ways that are otherwise difficult form the comamnd line. Science gateways can be built on the foundation provided by those services.

Users can access several NERSC resources via Globus grid interfaces using X509 grid certificates. NERSC is part of the Open Science Grid (OSG), and is available to select OSG Virtual Organizations for compute and storage resources.

The NERSC Grid infrastructure is based on the Globus Toolkit 4.0.x which is distributed with the VDT (Virtual Data Toolkit) as part of the Open Science Grid software stack.
