NASA Team Releases Mars Landing Simulation Data to Encourage New Research into Spacecraft Descent Technologies

Scientists at NASA aim to one day land giant payloads on Mars, but safely descending passengers, flight crew, and other equipment in an atmosphere much thinner than Earth’s poses a significant challenge. Scientists studying potential Mars landing technologies need large-scale computational resources to model such scenarios, and to accurately model…

Simulating the Stars at Exascale Requires HIP Solutions

As GPU architectures have become the standard for scientific computing, application teams have had to retrofit their scientific codes to run on new systems. Even teams with codes that have been re-engineered for GPUs must continually adapt them for new architectures. Evan Schneider of Princeton University, though, began developing her…
