Note: Beginning October 1, NAS will implement a separate allocation and accounting for GPUs. Please stay tuned for a separate call for GPU requests later this summer.

All NASA mission directorates are currently gathering requests for High-End Computing (HEC) time on resources at the NASA Advanced Supercomputing (NAS) facility for awards to begin October 1, 2023.

• Aeronautics Research Mission Directorate (ARMD)
• Exploration Systems Development Mission Directorate (ESDMD)
• NASA Engineering and Safety Center (NESC)
• Science Mission Directorate (SMD)
• Space Operations Mission Directorate (SOMD)
• Space Technology Mission Directorate (STMD)

ARMD, ESDMD, NESC, SMD, SOMD, and STMD managers will consider eligible requests submitted via the HEC Request Management System (RMS) to the rolling submission calls by the July 20, 2023 deadline.

For work that is supported by NASA outside of ARMD, ESDMD, NESC, STMD, SOMD, and SMD, you may renew your project(s) and apply for time under the MISC (miscellaneous) category. The MISC category does not have a share of HEC resources, so requests will be evaluated on a case-by-case basis with no guarantee of an award of computer time.

For Continuing Projects

1. Log in to https://request.hec.nasa.gov/.
2. Confirm your project’s Period of Performance end date is correct. If not, click on Request New End Date. Do not forget to request more resources for the new fiscal year, after completing the extension form. Unused FY23 allocations will not be rolled over.
3. Review your requested resources for FY24 (and any future years). If you need to adjust your requested resources, click on the Request More Resources link, and complete the form. You can enter a negative number to decrease your request.
4. If your project’s end date and preferred resources for FY24 are correct, there is no action required.

Note: You should only submit a new request if significant changes to the project are required. For minor updates, such as a new WBS or change to funding manager, please contact support@hec.nas.nasa.gov.

Projects that do not have an FY24 allocation will be disabled on October 10, 2023.

For New Projects

For new projects, please submit a request if:

• You are responding to a Research and Opportunities in Space and Earth Sciences (ROSES) solicitation (SMD reviews eligible requests quarterly).
• You have NASA funding for a new project that you want to begin October 1, 2023.

To submit your request, go to https://request.hec.nasa.gov.

For questions on the allocation process or your specific project, please contact support@hec.nasa.gov.
