[slurm-users] job_desc.pn-min-memory in LUA jobsubmit-plugin

[Davide DelVento]

I don't have an answer for you, but I found your message in my spam folder.
I brought it out and I'm replying to it in the hope that it gets some
visibility in people's mailboxes.

Note that in the US it's SC week and many people are or have been busy with
it and will be travelling in the next days, then next week is Thanksgiving
and some people take the week off, so you may still have to wait for a week
or so to get an answer -- unless you get from somewhere else in the world,
that is ;-)
