How to run a function exactly once on each node?

[mannyv]

Hi @dutch,

Check out this recent post for one way to address this problem.

How to create @ray.remote jobs that will only run on the workers from the local node?

One possible solution is to specify the custom resources on a node that has files; ray start --resources=’{“files”:1}’ @ray.remote def f(): pass ray.get(f.options(resources={"file":0.001})).remote()
