NERSCPowering Scientific Discovery Since 1974

Dirac GPU Cluster

Current Status: Up

Dirac is a testbed experimental system and is not considered a NERSC production system. Therefore, policies regarding user access and staff support differ substantially from other NERSC systems. As Dirac is a sub-cluster of Carver, whenever Carver is down for maintenance Dirac will be down. Every effort will be made to give users advance notice in these situations.  Users who desire access to this resource must have research objectives that align with Dirac's research objectives.
