[slurm-users] Re: Shared queue: how to request full node with all resources?

Hi,

Could --exclusive ( [ https://slurm.schedmd.com/sbatch.html#OPT_exclusive | https://slurm.schedmd.com/sbatch.html#OPT_exclusive ] ) do the trick?

Hi,

With a partition with "OverSubscribe=FORCE" set, is there a way to request all the node resources? I see "--mem=0" does that for memory. But I do not see an option to request all the CPUs and GRES/TRES such as GPUs. I tried "--nodes=1 --ntasks=1 --cpus-per-task=0", but "--cpus-per-task=0" does not do the same thing as "--mem=0".

In other words, is it possible to have a queue where nodes can be shared between jobs, but have a simple way for an sbatch script to request the full node with all its memory, cpus, and other resources? We have a heterogeneous cluster, so telling users (or jupyterhub scripts) to list exactly the resources they want doesn't really work.

thanks, dustin
