I missed this before Barbara, sorry - that's really good to know that
the options aren't mutually exclusive, thank you!
Anyone know if the new GPU support allows having a different number of GPUs per
node?
I found:
https://www.ch.cam.ac.uk/computing/slurm-usage
Which mentions "SLURM does not support having varying numbers of GPUs per node
in a job yet."

We have SLURM 19.05. and implemented the cons_tres scheduling type.
It does work only by specifying the --gpus-per-node when submitting the
job. And there are many more options.
I found this presentation to be quite informative:

No worries Chris!
Sounds like other than the new requests for gpu specifics, things should just
work when upgrading to 19.05 as slurm is likely backwards compatible with the
previous setup gres stuff.
Yup, we

Hi,
Excuse me if this has been explained somewhere, I did some searching. With
19.05, is there any reason to have gres.conf on the GPU nodes? Is slurm smart
enough to enumerate the /dev/nvidia* devices? We are moving to 19.05 shortly,
any gotchas with GRES and GPUs? Also, I'm guessing now, the
