<div>
<p class="MsoNormal"><span class="apple-tab-span"> </span>We're using SLURM 17.11 and trying to control job submission from user via Lua plugins job_submit.lua. Number of nodes specified via "-N" option in SLURM job script is crucial for us,
but I found no where to get it. According to job_descriptor defined in <a href="https://github.com/SchedMD/slurm/blob/slurm-17.11/slurm/slurm.h.in">https://github.com/SchedMD/slurm/blob/slurm-17.11/slurm/slurm.h.in</a> , in contrast to num_tasks, 'num_nodes'
is not a member of job_descriptor structure. I tried job_desc.num_nodes in job_submit.lua, then it turns out be nil.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal"><span class="apple-tab-span"> </span>I wonder is 'num_nodes' the correct name to get the requested number of nodes. And is any way to get number of nodes in job_submit.lua?<o:p></o:p></p>
