[slurm-users] Complex resource requests for a single job

[Christopher W. Harrop]

Hi Jeff,

That’s what I first looked at, but that page is so confusing I couldn’t decipher if that was indeed what I was looking for.  A SchedMD person replied to me privately and pointed me to the same location.  After a bit of back and forth, it is indeed the heterogeneous job that I am looking for.  But, unfortunately, it turns out that running an executable across multiple components is not supported until version 18.08, which isn’t out yet.  But, I did get my question answered.

So, I’ll have to wait for the next version.  I think it would be helpful to me and others if that page was reworked to describe more clearly what a heterogeneous job is, what a component is, and provide more examples that include basic usage as well as advanced usage.  

Chris
