The benefit with partitions is that you can set a bunch of options that are not
possible with just features like the amount of memory per core or per gpu and
the amount of cores per gpu (the defaults). Or have a different walltime or
priority.
We have a submit filter that will do something like:
if job_desc.partition == nil then
if job_desc.tres_per_job ~= nil or job_desc.tres_per_node ~= nil then
job_desc.partition = "gpu_1,gpu_2"
end
end
So it's transparent to the users. You can make a partition of GPU nodes where
CPU jobs are and are not allowed.
