Expanding the range of resources available to researchers in Earth system science and related fields, ACCESS now includes the Derecho system as an option for Explore ACCESS and Discover ACCESS projects. Derecho is the flagship supercomputing system at the National Science Foundation (NSF) National Center for Atmospheric Research (NCAR). Installed in 2023, the system is used annually by more than 1,500 researchers in the Earth system science community.
Derecho features 2,488 compute nodes, each with 128 AMD Milan cores, and 82 GPU nodes, each with four NVIDIA A100 GPUs. An HPE Cray EX cluster, Derecho has a peak performance of 19.87 petaflops. Through Explore ACCESS and Discover ACCESS requests, Derecho is available to:
- U.S.–based researchers with an NSF award in the Earth system sciences or related to Earth system science
- Graduate students, postdocs and new faculty whose Earth system science work does not have external support
- Teachers and professors in classroom or instructional settings focused on Earth system science
Additional Derecho allocation options, including opportunities for large-scale projects, are provided separately through NSF NCAR.
