I asked about this on the slack channel, but didn’t get a response.

I’ve been using `SlurmClusterManager` and been pretty satisfied with it, but there’s a job I want to accomplish with it that I’m not sure how to do.

The job I want to do has `m` cases. each of these cases can be done independently, and I would like to assign a whole node, with all its cores `n`, to work on each case. If each of the `m` cases only required 1 core, then, I would have run my `sbatch` command with `--ntasks=m` and `--cpus-per-task=1` ; the Julia code would then work fine with the naive `pmap` command.

Any suggestions would be appreciated. As indicated, my cluster uses Slurmn for scheduling.

If I am not wrong you want the --exclusive flag

I think I know how to get the resources I want from the cluster manager, in terms of getting `m` nodes and all `n` cores on each of those nodes. What I’m more concerned with is how, presumably within Julia, I get it to assign one piece of the job to node 1, using all `n` cores on node 1, another piece of the job to node 2, using all `n` cores on node 2, etc.
