Allocations of Computer Time and Storage

Allocations Overview and Eligibility

A researcher may apply for an allocation of NERSC resources if their research project is funded by the DOE Office of Science, or if their research project is relevant to the mission of one of the six Offices of Science (ASCR, BES, BER, FES, HEP, NP). Read More »

The NERSC Allocation Request Form (ERCAP)

Requests to use NERSC resources are submitted annually via a web form known as the ERCAP (Energy Research Computing Allocations Process) Request Form. ERCAP is accessed through the NERSC Help Desk web interface and is available year-round. Read More »

Allocation Proposal (ERCAP) Deadlines

While the majority of awards are made once a year, the ERCAP process is open year-round. Startup projects, which are awarded by NERSC, may be submitted at any time. Read More »

Requesting an Increase in Allocation

If your project runs out of  time the project PI or its proxies may request additional time by sending an email to the DOE Allocations Manager responsible for NERSC Allocations in your DOE Science Program. For contact information for DOE Allocations Managers see: DOE Office of Science Programs and Allocation Managers. If your project runs out of HPSS Archival Storage Quota this is usually managed by NERSC. If you need an increase in your HPSS storage quota, log in to the NERSC Help Desk,… Read More »

Allocation Reductions

MPP (or computational) repositories that haven't used significant amounts of time are adjusted at certain times by transferring a part of the unused balance to the corresponding DOE Office reserve. Read More »

Managing Your Allocation and Your Users

NESAP Application Process

NERSC Exascale Science Application Program Application Process For information about the NESAP for Data Program, see this announcement. The National Energy Research Scientific Computing (NERSC) Center has completed accepting applications from NERSC users for the NERSC Exascale Science Application Program (NESAP). Through NESAP, NERSC will partner with approximately 20 application teams to help prepare codes for the Cori architecture. A key feature of the Cori system is the Intel Knights Landing… Read More »
