NERSCPowering Scientific Discovery Since 1974

Burst Buffer Early User Program

NERSC selected a number of HPC research projects to participate in the center’s new Burst Buffer Early User Program, where they were able to test and run their codes using the new Burst Buffer feature on the center’s newest supercomputer, Cori. The following are the applications selected to receive early access to the Burst Buffer, and in some cases active NERSC support in tailoring their code to take advantage of the Burst Buffer features. Please see this news article for more details on the Burst Buffer Early User Program. In addition, "Accelerating Science with the NERSC Burst Buffer Early User Program" was awarded Best Paper at the 2016 Cray User Group meeting.

NERSC used the following criteria to evaluate submissions:

    • Representation among all six Offices of Science

    • Ability for application to produce scientific advancements

    • Ability for application to benefit significantly from the Burst Buffer

    • Resources available from the application team to match NERSC/Vendor resources

Examples of how the Burst Buffer could improve application capability or performance include (see also the Burst Buffer webpage for more details on how the Burst Buffer can be used):

    • IO improvements for:
      • High bandwidth reads and writes, e.g. checkpoint/restart
      • High IOP/s (input-output operations per second), e.g. non-sequential table lookup
      • Out-of-core applications
    • Workflow performance improvements:
      • Coupling applications, using the BB as interim storage
      • Optimizing node usage by changing node concurrency part way through a workflow (using a persistent BB reservation)
    • Analysis and Visualization:
      • In-situ / in-transit
      • Interactive (using a persistent BB reservation)
