SCIENCE MISSION DIRECTORATE ALWAYS OPEN CALL

Always Open Call for Computing Time Requests to Use NASA High-End Computing Resources for Science Mission Directorate-Supported Research

Submission Deadline Allocation Award Year Begins
September 20 November 1
March 20 May 1

If you are currently supported to perform research for NASA’s Science Mission Directorate (SMD) and require NASA High-End Computing (HEC) resources, you can request specific computing time allocations to use HEC resources at the NASA Center for Computational Sciences (NCCS), located at the Goddard Space Flight Center, and at the NASA Advanced Supercomputing Division (NAS), located at Ames Research Center. Prospective users supported by other NASA mission directorates should consult the Process Overview to determine access procedures and deadlines for those mission directorates.

If you have SMD support, submit your request in e-Books, following the submission instructions and link provided there for the SMD Rolling Call. Information on all available HEC resources, including computing systems, storage, and support services, can be found on Systems and Services At A Glance. SMD HEC computing time allocations are made through a process designed to ensure correspondence with SMD programmatic research priorities. No direct funding will be provided through this award of computing time.

All requests for SMD HEC computing time for new and continuing projects must be made through the e-Books submission website. The Cover Sheet form with a summary of the planned research and the Summary of Requirements form must be completed and submitted in e-Books. There is help documentation on the site to assist you. Requests of any size submitted by the deadlines given above will be considered for 1-year awards beginning November 1 or May 1. Final award decisions during these regular allocation cycles are made by SMD discipline program managers. Awardees are notified as soon as decisions are available.

Any request not submitted by the deadline to be considered by SMD discipline program managers in the regular cycle will be considered out of cycle for limited awards if capacity is available. Requests for small allocations (<=100,000 processor-hours on one resource at NAS or NCCS) may be awarded with NAS or NCCS authorization and will expire at the start of the next regular cycle. Larger out-of-cycle requests must be authorized by the HEC Program at NASA Headquarters.

Principal Investigator (PI) requests for additions to allocations of up to 100,000 processor-hours or 20% of the award during an award period should be emailed to support@hec.nasa.gov, and will be granted at the discretion of the NAS or NCCS Project Managers when capacity is available. If the increase is not sufficient, the PI should submit a continuation request in e-Books for consideration during the next regular cycle. Larger additions need authorization from the NASA Headquarters HEC Program.
