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.
Updates and Status
A discussion mailing list has been created so users can ask questions and help each other, gpgpu-discuss@nersc.gov. All users with accounts on Dirac will be added to this list. Please report system problems to the NERSC consultants at consult@nersc.gov. Read More »
