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.


Visualization of gravitational waves emitted by two black holes as they spiral together and merge
04.18.16 – NASA's Fermi Telescope Poised to Pin Down Gravitational Wave Sources
A fascinating video developed by NASA Advanced Supercomputing (NAS) Division visualization experts shows gravitational waves emitted by two black holes as they spiral together and merge. Goddard Space Flight Center scientists used the NAS Pleiades supercomputer to simulate the first-ever detection of gravitational waves, announced on February 11 by the Laser Interferometer Gravitational-Wave Observatory (LIGO).

03.23.16 - Lesley Ott - Knows Where Your CO2 Goes
The NASA Global Modeling and Assimilation Office meteorologist uses models of the atmosphere, land, and ocean to try to understand how carbon moves through the Earth’s system.
Visualization of the polar vortex in the troposphere (red) and the stratosphere (blue) distorted over North America as an outbreak of cold surface air (cyan) moved south over the eastern side of the USA
2.28.16 - Tropospheric and Stratospheric Circulation Changes Related to the Cold Outbreak Over the Eastern US During the Week of 8-14 February 2016
The Global Modeling and Assimilation Office 10-day global forecast system, which runs at the NCCS, captured relocations of the tropospheric jet stream and the stratospheric polar vortex.
Visualization of sea surface temperatures in Pacific Ocean near South America
2.25.16 - NASA Sees a Different Kind of El Niño
A new NASA visualization shows the 2015 El Niño unfolding in the Pacific Ocean, as sea surface temperatures create different patterns than seen in the 1997-1998 El Niño. Computer models are one tool that NASA scientists are using to study this large event.
