The NERSC Allocation Request Form (ERCAP)

Resources Requested Tab

NERSC's computational resources share a common "MPP" (which stands for Massively Paralle Processing) allocation.  See Usage Charging.

Under Alloc Type select one of:

• DOE Production:  for  production-ready projects, including SciDAC projects, awarded by DOE
• Startup:  for PIs who wish to investigate using NERSC resources for new projects
• ALCC Awards: set by NERSC for DOE ALCC awards
• Education: if the project is for classroom teaching
• NISE Awards: set by NERSC for NISE awards

You can ignore the Cloud resource line, or enter 100,000 hours.  All production level MPP projects will start the year with 100,000 "cloud hours".  Startup repos will have 15,000 "cloud hours".  These cloud hours get replenished duting the year as they are used and if sufficient resources are available.  These cloud hours are used with the special queues available from Carver.  See Carver Queues.

All NERSC projects have accounts on the mass storage system, HPSS. The storage accounting units are SRUs (Storage Resource Units). A SRU Calculator can help you estimate your SRU requirements. See HPSS Charging.

The HPSS repository name is usually the same as the MPP or PDSF repository name. For new projects you may see a number (as part of the validation process this will be corrected to be the same as the MPP or PDSF repo name).
