<div dir="ltr">Hi,
<div><br>
<div>Currently, when specifying n to say 4 to turbine-aprun-run.zsh, it creates a jobdef with 4 nodes but runs only 4 procs on these nodes wasting c-1 cores per node. Is there a way to specify the corespernode for target architecture and let the aprun script
pick that up and launch appropriate number of procs?</div>
</div>
<div><br>
</div>
<div>Thanks,</div>
