Ookami Queues

There are five queues available on Ookami. The queues are managed by the Slurm scheduling software. Four of the five Ookami queues use the same 48 core A64FX nodes so your choice among these queues depends on the length of time needed to run your job. The fifth queue, rome-128core , provides acess to a single AMD Rome node with 128 cores and 512 Gb of memory.
