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).

01.19.21 - 2020 HEC Needs Assessment Report Now Available
The NASA High-End Comuting (HEC) Needs Assessment report documents the HEC users’ needs raised during a virtual workshop that took place June 1–19, 2020 in terms of computing capacity, technology, services, human resources, and programmatic. The HEC Program will use the information to develop future investment and program implementation strategies.

09.13.21 - The Rock That Ended the Dinosaurs Was Much More Than a Dino Killer
In this New York Times interview, NASA Advanced Supercomputing (NAS) user Bill Bottke from the Southwest Research Institute described NASA’s Pleiades supercomputer as a “game changer” for his research team, which ran simulations of 130,000 model asteroids evolving over hundreds of millions of years—including the one that may have killed off the dinosaurs

09.03.21 - NASA's First Lunar Rover will Scour the Moon's South Pole for Water in 2023
With NASA planning to land the world's first autonomous lunar rover to search for water deposits, scientists are creating 3D road maps for the rover to safely explore the lunar surface using the agency's open-source Stereo Pipeline software tool and NAS's Pleiades supercomputer.
Visualization of air temperature anomaly, ice surface melt extent, and 500 mPa height during peak melt extent on Greenland
08.31.21 - GMAO Science Snapshot - 2021 Greenland Ice Sheet Melt Events: A Variety Pack
The summer of 2021 is remarkable for a series of late-summer melt events that have covered large areas of the Greenland Ice Sheet, even extending to its highest point at Summit Station. These events have been captured in the GMAO Forward Processing (FP) analyses and in routine numerical weather predictions produced from the GEOS forecast model, running at the NASA Center for Climate Simulation (NCCS).
Visualization of turbulent flows around aircraft
08.30.21 - NASA Glenn Aerospace Engineers Use Supercomputers at NAS to Predict Turbulent Air Flows
NAS experts recently helped aerospace engineers at NASA’s Glenn Research Center optimize their high fidelity Wave-Resolving Large-Eddy Simulation (WRLES) code, which they use to predict turbulent flows that occur around aircraft. These predictions can help design engineers reduce noise during takeoff and landing, and improve fuel efficiency during all stages of flight.
