what if we do keep this as part of the prolog?

Its a deadlock prevention, even through we added it for shared file.
Any scenario where more processes access this file and we end up in a deadlock scenario can be prevented if we keep it and we have logs showing that we were in deadlock

You also need to chnage the nvidia-imex-status.job file which points to using a config specific file.

good catch, done!
…ocal IMEX nodes config, rather than the shared one.
…status by using the local IMEX config file rather than the shared one.

We can remove this file. We should no longer specify the configuration file if not needed!

I remember it was necessary, but apparently it is not when the default location is used

Description of changes
In aws/aws-parallelcluster-cookbook#3029 we moved from shared IMEx configurations to local ones. In this PR we adapt the prolog accordingly.
Also, we fixed an assertion made on IMEx logs, which used to check the logs in the head node, but it should check the compute nodes.
