University Allocations of NSF NCAR HPC Resources Available
NSF NCAR's Computational and Informations Systems Lab (CISL) makes high performance computing (HPC) resources hosted at the NCAR Wyoming supercomputing center available to university researchers and educators.
While smaller university allocations are reviewed and granted on a rolling basis, large allocations are reviewed twice each year. The next deadline for large allocation requests is March 4, 2026.
From the announcement by CISL:
CISL is now accepting large-scale allocation requests from university-based researchers for the Derecho system as well as the Casper data analysis and visualization cluster with a submission deadline of March 4, 2026. We are actively seeking projects that can take advantage of Derecho’s 328 NVIDIA A100 GPUs. CISL accepts requests from university researchers for large-scale allocations every six months.
At the CISL HPC Allocations Panel (CHAP) spring 2026 meeting, CISL will allocate up to 500 million core-hours and 500,000 GPU-hours on the Derecho system. Campaign Storage requests will be highly scrutinized closely due to the current high levels of usage in that file system, therefore researchers are strongly encouraged to propose workflows that can leverage Derecho's scratch space, potentially with an increased storage quota.
Researchers should include the Casper system in their work plans to minimize the need to move data to their home institutions for analysis. Casper provides resources for data analysis and visualization activities and single-node jobs.
Researchers are encouraged to review the instructions before preparing their allocation requests. See our allocations documentation at https://arc.ucar.edu/docs/university-allocations. Please be aware that instructions for preparing your main request document have been updated to reflect increased scrutiny of storage requests.
