minicord : python3 ?

[nyue]

I saw some message about errors when using minicoord with python3, are they resolved ? That message was marked answered.

I am getting the follow errors

(omr_venv) ubuntu@san1-c2-4-8oaict:/opt/MoonRay$ python -i /opt/MoonRay/installs/openmoonray/python/minicoord/run.py

I repeated the above test on Rocky Linux 9, same error, this looks to be OS agnostic

Hi,

The WARNING means that minicoord received a client request to allocate a new Arras session, but couldn't find a node with enough free cores/memory to satisfy the request. It isn't necessary a problem with minicoord : you just need to either wait for other sessions to finish or add more nodes to minicoord.

The ERROR means that minicoord returned an error status (503) to the client requesting the session, indicating the request couldn't be satisfied : again, this is not a issue in minicoord, but the normal way it responds to requests that cannot be filled. The client should be able to interpret this response and report that the session cannot be run without more resources.

I need to be less aggressive with the memory setting.

All good. I am able to continue my testing now.

Thank you @rgwilson68
