NERSCPowering Scientific Discovery Since 1974

High-Impact Science at Scale on Cori

August 24, 2017

NERSC's High-Impact Science at Scale program provides competitively selected projects an allocation of time to use Cori'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 a Call 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. In 2017, eight awards were given, each with enough time to make significant progress in on the proposed research problem.

Summaries, results, and publications are being prepared, but some highlights include

  • A simulation of the intergalactic medium in the largest volume so far (Lukic)
  • Modeling the break up of a collisional current sheet in plasma conditions similar to a solar flare (Stanier) 
  • Emittance degradation observed in a simulation of a Laser Wakefield Accelerator leading to a proposed solution (Vay)
  • Insight into the properties of strongly interacting matter at the time where quarks and gluons, the fundamental degrees of freedom in strong interaction physics, start forming bound states and give rise to ordinary matter such as protons and neutrons that form the nuclei of all atoms (Karsch)
  • One of the largest "GW"  calculations ever performed: to predict the defect energy-states in Silicon Carbide - of interest in the design/development of Quantum Computers. The team  accurately determined energy values, alignments and defect orbitals.

2017 Projects

The following projects were awarded time through the program, which allocated a total of about 450 million NERSC Hours.
