I'm trying to run a parallel Fluent job that spans multiple nodes on a Linux cluster.  The job works fine when run on a single node, but a multi-node job fails with the error "unable to run bstrap_proxy on (hostname)."   

The cluster is running Linux (RHEL 9.4) with Slurm 24.05.   I've tried Ansys 2024R1 and 2023R2.  They both fail in the same way.

I strongly suspect the issue is related to Slurm 24.05.  Are there any workarounds?

I saw another issue about AnsysEM that provided a patch for the HFSS slurm_srun_wrapper.sh script.   Perhaps a similar issue affects fluent.
