Strange Behaviour of ray on distant node

How severe does this issue affect your experience of using Ray?

  • Medium: It contributes to significant difficulty to complete my task, but I can work around it.

Dear all,
Maybe it is a well known problem but I tried to check this problem that I don’t understand.
Working with a slum management I have a weird behaviour.
Is is really slow if I launch the code on a distant node but I behave normally if I ssh to the node and launch the same code. I init the ray cluster with same arguments on the same node.

Do you have an explanation?
Thank you


Hey @FB1 , welcome to the community!

Would you mind sharing a bit on how do you “launch the code on a distant node”? Do you do it through ray client or do you do with ray job directly?
