Hello All, I saw this post from 2014 and I was wondering if anyone had a good solution. Post:
https://groups.google.com/forum/#!searchin/slurm-users/split$20cores$20partition%7Csort:date/slurm-users/R43s9MBPtZ8/fGkIvSVMdHUJ My situation is similar. I have a GPU cluster with gres.conf entries which look like: NodeName=gpu-XX Name=gpu File=/dev/nvidia[0-1] CPUs=[0-5] NodeName=gpu-XX Name=gpu File=/dev/nvidia[2-3] CPUs=[6-11] However, as you can imagine 8 cores sit idle on these machines for no reason. Is there a way to easily set this up? The post mentioned using QOS, but for example if slurm fills up CPUs 0-7 and uses 8-11 for the GPU that would be disastrous. I could use block distribution by default, but I don't think I will ever be able to keep N cores on the socket idle if N GPUs are idle. It might be worth noting that I am trying to avoid preemption of these resources. However, it might be the only way (e.g. GPU jobs preempt CPU only ones).
