High-End Computing Program

Delivering high-end computing systems and services to NASA's aeronautics, exploration, science, and space technology missions.


If you are a NASA-sponsored scientist or engineer, computing time is available to you at the High-End Computing (HEC) Program's NASA Advanced Supercomputing (NAS) Facility and NASA Center for Climate Simulation (NCCS).

04.27.16 - Allocation Period Start Date for All Organizations Changing to November 1
Starting November 1, 2016, the allocation period for all organizations will be November 1–October 31 each year. In order to transition to the November award cycle, all allocations for the May 2016 award cycle will be for only 6 months (ending October 31, 2016), instead of for one year.

06.01.16 – Pleiades Supercomputer Tops Six Petaflops, Long-Term Storage Capacity Tripled
As part of recent expansion work at the NAS Division, the agency's flagship supercomputer, Pleiades, received a boost in computing power with the installation of the latest generation of Intel Xeon processors, increasing the system's theoretical peak performance to over six petaflops. Additionally, new tape hardware was added to the facility's long-term mass storage system, tripling the data storage capacity.
