Athena and Cabeus Supercomputer Upgrades

Recently, two of NASA most powerful supercomputers were augmented with additional hardware, adding around 15 petaflops of computing capability for our users.

In October, we released the first of two expansions to the Cabeus supercomputer this year with the introduction of 188 NVIDIA Grace Hopper nodes, bringing the system's combined theoretical peak performance to over 25 petaflops (including the Milan/A100 nodes).

Then in early November, 512 AMD Turin nodes added to the Athena supercomputer were released to all NAS users. This almost 50% expansion brings the total count of nodes in the system to 1,536 and increases its theoretical computing power to over 30 petaflops, making Athena the agency's most power supercomputer to date.


NASA Ames’ Contributions to Roman’s Mission

Experts at NASA’s Advanced Supercomputing Division at Ames are advancing the Roman Space Telescope’s science by bringing extensive experience in data pipelines and mission operations to provide advice and guidance to the Roman project through key mission development phases. This ensures reliable performance of ground-based systems and operations so that science data processing is efficient and the quality and integrity of the resulting science data products is high.

Read more about how NAS fits into Ames Research Center's contributions to the Roman Space Telescope's mission.

NASA’s COFFIES Uses AI to Predict Storm-Causing Active Regions on Sun

A novel machine-learning model developed by team of astrophysicists and data scientists is capable of predicting the emergence of active regions on the Sun up to 12 hours before they appear. With the help of NAS supercomputers, the team developed an artificial intelligence approach to analyzing data captured by NASA's Solar Dynamics Observatory to capture subtle, time-based pattern changes on the solar surface before an active region takes shape.
