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).


Visualization of 3D multifluid magnetohydrodynamic simulations of the Moon
06.14.22 - Visualizing Mechanisms for Making Water on the Moon
Physicists at Princeton University are running simulations on the Pleiades and Electra supercomputers to trace the origin of water on the Moon. Their research illustrates a possible mechanism for lunar hydration: ionized oxygen transported by Earth’s magnetic field. To help the researchers gain insight into their complex computational results, NASA Advanced Supercomputing (NAS) visualization experts produced animations that help convey a dynamic system of ionized oxygen deposits.

06.14.22 - NCCS-Hosted Simulations Probe the Interactions of the Freshwater Yukon River and the Salty Arctic Oceany
The NASA Center for Climate Simulation (NCCS) Discover supercomputer powered a model NASA Goddard Space Flight Center scientists developed to simulate the physical properties and transport of water in the lower Yukon River and Northern Bering Sea — water that ultimately reaches the freshest of the world’s major oceans, the Arctic Ocean.

05.31.22 - Simulating Supersonic Parachute Inflation for Future Mars Landings
As shown by GEOS model forecasts run at the NCCS, April 2017 Middle East flooding resulted from a "dusty atmospheric river” attributed to major mineral dust sources in the region.
Visualization of model calculating the optical properties of water containing algae and other phytoplankton species
05.26.22 - Simulating Algae to Model Water Quality in Minutes
Researchers on the Biospheric Science team at NASA Ames Research Center use NAS systems to calculate the optical properties of water containing algae and other phytoplankton species—a key to determining the degree of water contamination and modeling water quality. Recently, NAS experts helped the team speed up their simulations, reducing the time required to perform calculations for single alga particle from two hours to just 18 minutes.

05.25.22 - NCCS User Spotlight: Goutam Konapala
As part of NASA’s celebration of Asian American and Native Hawaiian Pacific Islander Heritage Month, this spotlight shines on NASA Center for Climate Simulation (NCCS) user Goutam Konapala. We follow Konapala from his childhood in an Indian village to his computational research on Earth’s water cycle with NASA Goddard Space Flight Center’s Biospheric Sciences Laboratory and the University of Maryland, Baltimore County.
