ALCC Program Awards Nearly 6 Million Summit Node Hours Across 31 Projects

August 6, 2020

Aug. 6, 2020 — Each year, researchers are awarded computing hours at the Oak Ridge Leadership Computing Facility (OLCF)—a US Department of Energy (DOE) Office of Science User Facility located at DOE’s Oak Ridge National Laboratory (ORNL)—through the DOE Office of Advanced Scientific Computing Research’s (ASCR’s) Leadership Computing Challenge (ALCC).

The ALCC program grants the 1-year allotments to scientists from industry, academia, and national laboratories whose work emphasizes high-risk, high-reward simulations in energy-related fields. The program allocates up to 30 percent of the high-performance computing resources at the OLCF and at Argonne Leadership Computing Facility (ALCF), as well as up to 10 percent at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory.

This year, 31 research teams have been awarded a combined 5.87 million node hours on the Summit supercomputer, the OLCF’s 200 petaflop IBM AC922 system. The research performed through the ALCC program this year will range from the impact of jets on offshore wind farms to the structure and states of quantum materials to the behavior of plasma within fusion reactors—all computationally intensive scientific applications necessitating the power of a large-scale supercomputer like Summit.
