As Ole says, *always* upgrade slurmdbd first, then slurmctld and finally
slurmd's. This is required because of the way the RPC protocol support

Hi Bas,
Your order of upgrading is *disrecommended*, see for example page 6 in
the presentation "Field Notes From A MadMan, Tim Wickberg, SchedMD" in
the page https://slurm.schedmd.com/publications.html
Versions may be mixed as follows:
slurmdbd >= slurmctld >= slurmd >= commands
Thanks

Pretty sure you don’t need to explicitly specify GPU IDs on a Gromacs job

Hi,
I run gmx 2019 using GPU
There are 4 GPUs in my GPU hosts.
I have slurm and configured gres=gpu
