Hi there,

Is it possible to run rollout workers on the head node in SLURM setup?
RW: RolloutWorker — Ray 2.2.0
RCluster: Key Concepts — Ray 2.2.0
SLURM note: Deploying on Slurm — Ray 2.2.0

Yes, absolutely.
Simply provide a node that has enough space to accommodate the rollout workers and they will be scheduled there.
