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 »

Requesting an Increase in Allocation
If your project runs out of time the project PI, or one of their proxies, may request additional time by submitting the Computing Time Increase Request form (requires login). To access the form, log in to the NERSC Help Desk at https://help.nersc.gov, and click the Open Request icon, then select the Computing Time Increase Request from the Request Forms menu. Fill in the form with the project, type of Node hours (CPU or GPU), number of Node hours, and a justification for the… Read More »
