Alabama Supercomputer Center Moves from Slurm to Altair PBS Professional

The Alabama Supercomputer Center (ASC), operated by the Alabama Supercomputer Authority, provides high-performance computing (HPC) services to students, faculty, and staff across the state. Unlike its predecessor, which ran Slurm, ASC’s newest system, ASA-X, uses the Altair® PBS Professional® workload manager. A federal government HPC system managed by the same systems integration contractor had recently undergone the same transition — and the team at ASC knew the change was not to be undertaken lightly.
