You can find the list of 2023 project allocations from the DOE INCITE program here [1]. INCITE allocates the majority of compute hours at the Leadership Computing Facilities, which includes the systems at Argonne and Oak Ridge.
Believe you’re thinking of the HPC facilities at LLNL and LANL. Frontier is run under DOE ASCR as one of the Leadership Computing Facilities (LCF), which focus mainly on open science use cases. Most of the compute hours in the LCFs is allocated via DOE INCITE and ALCC programs.
