How to run a script on all cluster nodes

Ray Clusters

Hi,

What would be the best way to run a script in parallel on all (or subset) of current worker nodes ?

Thanks

Assuming you meant a python job (ray app), then try placement group strategy=“STRICT_SPREAD”. For details check out placement group.

Thanks for answering! However, I meant literally running same script at all nodes i.e. mpirun style (or slurm sbatch style)
