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).

11.03.16 – SMD Computing Time Requests Exceed Capacity
Continuing a multi-year trend, Science Mission Directorate (SMD) computing time requests far exceeded capacity at both the NASA Advanced Supercomputing (NAS) Facility and the NASA Center for Climate Simulation (NCCS). As a result many principal investigators received smaller allocation awards than they requested.

09.22.16 - Galactic Fireworks Illuminate Monster Hydrogen Blob
An international team of researchers using the Atacama Large Millimeter/submillimeter Array and other telescopes has discovered the power source illuminating a so-called Lyman-alpha Blob—a rare, brightly glowing, and enormous concentration of gas in the distant universe. Simulations were run on the NAS facility's Pleiades supercomputer.
Sea surface temperature patterns of the 2015 El Niño in the Pacific Ocean
09.13.16 - After Strong El Niño Winter, NASA Model Sees Return to Normal
Not too hot, not too cold – instead, water temperatures in the equatorial Pacific Ocean should be just around normal for the rest of 2016, according to forecasts from the Global Modeling and Assimilation Office run at the NCCS.
