NERSCPowering Scientific Discovery Since 1974

High-Impact Science at Scale Program

NERSC's High-Impact Science at Scale program provides competitively selected projects an allocation of time to use NERSC's unique capabilities to deliver high-impact science. Selected projects use NERSC resources at scale to investigate key science problems that they would not otherwise be able to address. Teams were selected following Calls for Proposals, in which responses were reviewed for the ability to scale well on Cori KNL nodes, potential  to deliver a significant science result, a reasonable ratio of feasibility to risk, and the appropriateness of approach and resources requested. 

2022 Projects

The High-Impact Science program for 2022 is devoted to [email protected].

2021 Projects

The High-Impact Science program for 2021 continued support for COVID-19 related research and exascale application development related to the Exascale Computing Project.

2020 Projects

The High-Impact Science program for 2020 was dedicated to COVID-19 related research.
