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 Information Management (NIM) web interface and is available year-round. 

If you are new to NERSC and want to apply for an allocation as a new Principal Investigator please read Applying for your First NERSC Allocation.

To access ERCAP, point your browser to  nim.nersc.gov, and login to NIM. Click the My Stuff menu and select My ERCAP Requests.

In general existing projects should be renewed for the next allocation year - you should not start a new request if you have an existing repository.  Renewing carries forward most of the responses to the request questions and preserves the project's user list.
