Thanks Ole, for this clarification, this is very good to know.
However, the problem is that the very example provided by slurm itself
is the one that has the error. I removed the unpack part with the
variable arguments and that fixed that part.
Unfortunately, the job_desc table is always empty so
Hi Davide,
In your slurmctld log you see an entry "error: job_submit/lua:
/opt/slurm/job_submit.lua".
What I think happens is that when slurmctld encounters an error in
job_submit.lua, it will revert to the last known good script cached by
slurmctld and ignore the file on disk from now on, e
No, I never moved that file from the Linux cluster (and I do the
editing with VIM which warns me of that possible issue).

Possibly way off base, but did you happen to do any of the editing in
Windows? Maybe running into the cr/lf issue for how windows saves text

Very frustrating that even the simple example provided in the release

Hi Davide,
I suggest that you check your job_submit.lua script with the LUA compiler:
luac -p /etc/slurm/job_submit.lua
I have written some more details in my Wiki page

Thanks again to both of you.
I actually did not build Slurm myself, otherwise I'd keep extensive
logs of what I did. Other people did, so I don't know. However, I get
the same grep'ing results as yours.
Looking at the logs reveals some info, but it's cryptic.

Did you install all prerequiste packages (including lua) on the server
where you built the Slurm packages?
On my system I get:
$ strings `which slurmctld ` | grep HAVE_LUA

Try setting logging to debug mode, then you can get some info from the logs.

lua is the language you can use with the job_submit plugin.
I was showing a quick way to see that job_submit capability is indeed in
there.
You can see if lua support is there by looking for the job_submit_lua.so
file is there.
It would be part of the slurm rpm (not the slurm-slurmctl rpm)
Thanks again, Brian, indeed that grep returns many hits, but none of
them includes lua, i.e.
strings `which slurmctld ` | grep -i job_submit | grep -i lua
returns nothing. So I should use the C rather than the more convenient
lua interface, unless I recompile or am I missing something?
On Thu,
I would be surprised if it were compiled without the support. However,
you could check and run something like:
strings /sbin/slurmctld | grep job_submit
(or where ever your slurmctld binary is). There should be quite a few
lines with that in it.

Thanks Brian for the suggestion, which I am now exploring.

Not sure if you can do all the things you intend, but the job_submit
script is precisely where you want to check submission options.

Hi,
I would like to soft-enforce license utilization only when the -L is
set. My idea: check in the prolog if the license was requested and
only if it were, set the environmental variables needed for the
license.
I looked at all environmental variables set by slurm and did not find
any related to
