Yes I tried it but whit the same result
[email protected] -cuda +cxx_exceptions fabrics=ucx -java -legacylaunchers
-memchecker +pmi schedulers=slurm -sqlite3 -thread_multiple +vt
You can compile wrf , when you sbatch your job it is running but it doesn´t do
anything and we get the same, with WCHAN=hrtime
0 S 4556 87383 87361 0 80 0 - 126676 hrtime ? 00:05:25

HI Angelines,
Could you try reinstalling with fabric=ucx and rerunning?
UCX is the preferred way to use Infiniband in the Open MPI 4.0.x release
stream.

Thanks in advance.

Hello Angelines,
Do you know how the Open MPI 4.0.3 package was configured and
built? That information would be useful to help diagnose the problem.
Thanks,
Howard

Subject: [EXTERNAL] [slurm-users] problems with OpenMPI 4.0.3
Good morning,
We have a cluster with two kind of infiniband cards, one connectx-4
and the other connectx-6.
Openmpi-3.1.3 works fine, but when we start with connectx-6 we
started to use openmpi-4.0.3 (that support connectx-6) and the programs that
have several parts, first a call to a secuencial program and inside it a call
to a parallel program, ? (in our case the program is WRF, but we have others
like this with the same problem), this kind of programs suddenly stop,
?..
0 S 4556 87383 87361 0 80 0 - 126676 hrtime ? 00:05:25
real.exe
0 S 4556 87384 87361 0 80 0 - 126677 hrtime ? 00:05:33
real.exe
0 S 4556 87385 87361 0 80 0 - 126675 hrtime ? 00:05:28
real.exe
??
The WCHAN=hrtime, and it looks that it is running, but really it
doesn?t work
We don?t know if it could be problem with slurm and this version
of openmpi? Any idea?

Greatly appreciated for your help. I will try to implement
following your suggestion.

Even without the slurm-bank system, you can enforce a limit on
resources with a QOS applied to those users. Something like:
=====
sacctmgr add qos bank1 flags=NoDecay,DenyOnLimit
sacctmgr modify qos bank1 set grptresmins=cpu=1000
sacctmgr add account bank1
sacctmgr modify account name=bank1 set qos+=bank1
sacctmgr add user someuser account=bank1
sacctmgr modify user someuser set qos+=bank1
=====
You can do lots with a QOS, including limiting the number of
simultaneous running jobs, simultaneous running/queued jobs, etc.
Unfortunately, the NoDecay flag is only documented to work on GrpTRESMins,
GrpWall, and UsageRaw, not on the job count.
So if you can live with limiting the number of simultaneous jobs
instead of a total number of jobs per time period, that?s possible with QOS.
Otherwise, maybe someone else will have an idea.

Hello all,
I?m Slurm beginner who try to implement our cluster. I would like
to know whether there are any Slurm credit/token system plugin such as the
number of job count.
I found Slurm-bank that deposit hour to an account. But, I would
like to deposit the jobs token instead of hours.
Thanks for any recommendation
Songpon
