I had the same issue although the system clocks were the same on the master and execute nodes. However, I was told to try to configure NTP (network time protocol). That did the trick for me.

I am running (just installed) slurm-11.17.6, with a master + 2 hosts. It works locally on the master (controller + execution). However, I cannot establish communication from master [triumph01] with the 2 hosts [triumph02,triumph03]. Here is some more info: 1. munge is running, and munge verification tests all pass. 2. system clocks are in sync on master/hosts. 3. identical slurm.conf files are on master/hosts. 4. configuration of resources (memory/cpus/etc) are correct and have been confirmed on all machines (all hardware is identical). 5. I have attached: a) slurm.conf b) log file from master slurmctld c) log file from host slurmd Any ideas about what to try next?
