05.22.24 - NASA and IBM Research Apply AI to Weather and Climate
A collaboration involving NASA and IBM Research has led to the development of a new artificial intelligence (AI) foundation model for weather and climate: Prithvi-weather-climate (Prithvi is the Sanskrit name for Earth). Participants include NASA High-End Computing’s NASA Center for Climate Simulation (NCCS) and NASA Advanced Supercomputing (NAS) Facility.

03.04.24 - Supercomputer Speeds Computations for NASA Research Projects
A new graphics processing unit (GPU)-based supercomputer has been added to the stable of NASA high-end computing resources operated at the NAS facility. Named Cabeus after a lunar crater near the Moon’s south pole, the system is already providing agency users with several petaflops of computational power and will increase our capability to run artificial intelligence and machine learning workloads that can benefit from GPU technology.
