World-class modeling, simulation, and supercomputing in support of the NASA mission
Using simulations run on NASA's Pleiades supercomputer, an international research team led by the University of Edinburgh discovered that the dynamo process generating the Sun's magnetic field originates from a relatively close 20,000 miles below the surface. Reported in the journal Nature, the discovery provides a vital clue in a mystery that has puzzled solar observers since the time of Galileo.
Scientists in the NAS Division are using NASA high-end computing systems to train machine learning models to more efficiently predict the appearance of sunspots on the solar surface. Their research could pave the way for early forecasts of upcoming solar activity to help mitigate its impact on space exploration, near-Earth activities, and technologies on Earth. An animation of data flow that enables a forecast of solar activity is featured in the NAS Scientific Visualization Gallery.
This talk will discuss how different machine-specific programming models have allowed us to extract maximum benefit from two successive top-ranked GPU platforms, namely Summit and Frontier, at the Oak Ridge Leadership Computing Facility (OLCF).
Supporting the NASA Planetary Defense Coordination Office, scientists in the NASA Advanced Supercomputing (NAS) Division's Computational Aerosciences Branch have kept their eyes close to Earth recently—focusing on what might occur if our planet should someday get hit by an asteroid, and what we might be able to do to mitigate the damage.

The NAS Division’s Visualization and Data Analysis team develops stunning images and videos to help scientists explore their ocean data using in-house developed analysis tools. Visualization researcher Nina McCurdy is thrilled to “to collaborate with devoted, world-class scientists doing such important, cutting-edge research.” The team offers both traditional and customized services to help users process, view, explore, and analyze complex scientific datasets.
Researchers in the NASA Advanced Supercomputing Division have developed new simulations that incorporate ground effect into their studies on the aerodynamic flow around urban air mobility vehicles (UAMs). The ground effect—where the ground surface is added to the computational model—is an important factor in making sure that real-world products are safe and efficient when released by industry manufacturers in the future.
A new GPU-based supercomputer has been added to the stable of NASA high-end computing resources at the NAS facility. Named Cabeus, the system is already providing users with several petaflops of computational power and will increase the agency’s capability to run artificial intelligence and machine learning workloads that can benefit from GPU technology.
Find out more about the Cabeus supercomputer and the NASA project running on the system.
