NERSC allocations and AY2027 call (ERCAP)
Reviewed NERSC resource allocations, subject to project approval and available resources.
Start here
Open at latest check: NERSC ERCAP initial requests Checked 13 November 2026.
Open-science and HPC-education teams seeking a reviewed NERSC allocation. Initial requests may be submitted at any time. New PIs need an ERCAP access account before preparing and submitting the allocation-year form.
The main AY2027 window has ended. Year-round initial requests remain separate and depend on programme fit, review and resources; ALCC uses a separate process. Official source and next step
Check current status and next steps
Who can apply?
Projects supporting the relevant DOE science programme or HPC education; exploratory and other project classes have separate conditions.
How do I take the next step?
New PIs first request ERCAP access, then submit the correct allocation-year request for review.
Recorded deadline
Recorded deadline: The pre-allocation-year 2027 window closed on 5 October 2026 at 5 p.m. PDT. NERSC accepts proposals throughout the year; additional allocations may be awarded while resources remain. The next pre-allocation-year call date is not recorded here.
Check the official programme before applying. A recorded region is not a decision about your eligibility, and an allocation is not guaranteed.
Evidence and limits
- The allocation year 2027 call opened on 10 August 2026 and closed on 5 October 2026 at 5 p.m. PDT. Proposals submitted by that deadline are due to receive a determination in the week of 14 December 2026. Source
- NERSC says it accepts proposals throughout the year and can make additional allocations while resources remain, but most resources are distributed before the allocation year begins. Source
- The current ERCAP guide accepts initial requests at any time and requires a new PI to obtain ERCAP access before submitting. Source
The general submission route was checked on 13 November 2026. Annual AY2027 dates retain their 12 October evidence and the main window has ended. Year-round submission is not a resource or award guarantee; ALCC is separate.
