ASCR Leadership Computing Challenge (ALCC)

ASCR Leadership Computing Challenge (ALCC) is sponsored by U.S. Department of Energy (DOE) Office of Science, Office of Advanced Scientific Computing Research (ASCR). The ALCC targets high-risk, high-payoff research aligned with DOE mission areas, providing time on Frontier, Aurora, Polaris, and Perlmutter. The 2026-2027 cycle accepts multi-year proposals.

The ALCC program is managed by the Advanced Scientific Computing Research (ASCR) program office in the DOE’s Office of Science.

ASCR stewards several high-performance computing user facilities including the National Energy Research Scientific Computing Center (NERSC) located at Lawerence Berkeley National Laboratory and the Leadership Computing Facilities located at Argonne National Laboratory (ALCF) and Oak Ridge National Laboratory (OLCF).

Each year, between 10%-30% of the available resources at these user facilities are available to research supported through the ALCC allocation program. The allocation year runs from July 1 – June 30 th of the subsequent year, with a possibility of renewal for up to 2 years.
