Allocation Reductions

Projects that are not using their allocation at a certain pace may have time returned to the allocation pool of their respective DOE Office of Science Program.  (ALCC, Director's Reserve,  Exploratory, and Educational projects are exempt from this reduction.)  Projects are reminded that they may still run, in the Overrun queue, when they have exhausted their allocation for the year.

Allocation Year 2021

The following schedule will be used for Allocation Year 2021 (which runs from January 20, 2021 through January 18, 2022). 

On May 4, 2021:

  • If a project has used > 5% and <= 10% of its allocation, we will reduce their allocation by removing 10% of the unused balance. 
  • If a project has used <= 5% of its allocation, we will reduce their allocation by removing 20% of the unused balance. 

On September 7, 2021:

  • If a project has used > 10% but <= 25% of its allocation, we will reduce their allocation by removing 25% of the unused balance.
  • If a project has used <= 10%, we will reduce their allocation by removing 50% of the unused balance.

Project Principal Investigators, PI Proxies or Project Resource Managers can request exemptions to this policy, but must make the request at least one week before the reductions are scheduled to take effect. Please make a request by creating a ticket at https://help.nersc.gov and include justification for the exemption.
