Issue on Quartz: HYDU_sock_connect unable to connect

[spasmann]

Running into an issue on Quartz when I submit jobs from my PC (jobs run normally when submitting submitting from my Mac). All PC batch jobs fail with multiple errors like:

[proxy:0:23@quartz2664] HYDU_sock_connect (lib/utils/sock.c:140): unable to connect from "quartz2664" to "quartz79" (No route to host)
[proxy:0:23@quartz2664] main (proxy/pmip.c:105): unable to connect to server quartz79 at port 43377 (check for firewalls!)
srun: error: quartz2664: task 23: Exited with exit code 5

This is occurring regardless of branch or input deck. Based on similar bugs here and here it seems to be an issue either with my ssh or hostname issue.

I've submitted an LC-Hotline ticket and will report back what they say.

Are you sure you are using the MPI package from quartz and building off of that? Type which mpirun, which mpiexec and or which srun. Also check the module maybe? If you tell me exactly what to pull I can start trying out different versions/distributions of MPI

Never heard back from LC-Hotline, but the issue went away the next day. Closing the issue for now.
