July 27, 2018 — The U.S. Department of Energy’s (DOE) ASCR Leadership Computing Challenge (ALCC) has awarded 20 projects a total of 1.5 billion core-hours at the Argonne Leadership Computing Facility (ALCF), located at DOE’s Argonne National Laboratory, to pursue challenging, high-risk, high-payoff simulations.

The Advanced Scientific Computing Program (ASCR), which manages some of the world’s most powerful supercomputing facilities, selects projects every year in areas directly related to the DOE mission for broadening the community of researchers capable of using leadership computing resources, and serving national interests for the advancement of scientific discovery, technological innovation, and economic competitiveness.

The ALCC program allocates up to 20 percent of the computational resources at ASCR’s supercomputing facilities to research scientists in industry, academia, and national laboratories. In addition to ALCF, ASCR’s supercomputing facilities include Oak Ridge Leadership Computing Facility (OLCF) at Oak Ridge National Laboratory and the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory. The ALCF, OLCF, and NERSC are DOE Office of Science User Facilities.

The 20 projects awarded time at the ALCF are noted below. Some projects received additional computing time at OLCF and/or NERSC. The awards began on July 1.
