NERSCPowering Scientific Discovery for 50 Years

201 Users Participate in Annual User Survey

February 1, 2006

The results from the 2005 user survey are now available and show generally high satisfaction with NERSC’s systems and support.

Areas with the highest user satisfaction include account support services, the reliability and uptime of the HPSS mass storage system, and HPC consulting. The largest increases in satisfaction over last year’s survey include the NERSC CVS server, the Seaborg batch queue structure, PDSF compilers, Seaborg uptime, available computing hardware and network connectivity.

Areas with the lowest user satisfaction include batch wait times on both Seaborg and Jacquard, Seaborg’s queue structure, PDSF disk stability, and Jacquard performance and debugging tools. Only three areas were rated significantly lower this year: PDSF overall satisfaction and uptime, and the amount of time taken to resolve consulting issues. The introduction of three major systems in the last year combined with a reduction in consulting staff explain the latter.

As in the past, comments from the previous survey led to changes in 2005, including a restructuring of Seaborg’s queuing polices, the addition of the new Jacquard and Bassi clusters, and upgrade of ESnet’s connectivity to NERSC to 10 gigabits per second.
