The U.S. Department of Energy’s ASCR Leadership Computing Challenge (ALCC) has awarded 24 projects a total of 1.7 billion core-hours at the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science User Facility.

Each year, the ALCC program selects projects with an emphasis on high-risk, high-payoff simulations in areas directly related to the DOE mission and for broadening the community of researchers capable of using leadership computing resources.
