Researchers using the PDSF cluster managed by NERSC will soon have access to more processing power and benefit from a higher speed network connection for accessing archived data.

New hardware is being shipped and is expected to be installed by the end of September. The additions include 48 nodes of dual Xeon processors and 10 nodes of dual Opteron processors. These will be added to the existing 550 processor cluster.

The system’s connection to NERSC’s internal network will be upgraded from a 2 gigabit switch to a 10 gigabit switch. This will improve the transfer rate of data between PDSF and NERSC’s HPSS archival storage.

Finally, some of the PDSF disk drives are also being upgraded. This is expected to add 12 terabytes of disk capacity to the cluster.
