The OpenFOAM demo can trigger this issue with v2023.06 of the EESSI production repo.

Also opened a pr to the docs with the workaround: EESSI/docs#172

OpenFOAM/bike_OpenFOAM8.sh

+surfaceFeatures 2>&1 | tee log.surfaceFeatures
+blockMesh 2>&1 | tee log.blockMesh
+decomposePar -copyZero 2>&1 | tee log.decomposePar
+mpirun -np $NP -ppn $PPN -hostfile hostlist snappyHexMesh -parallel -overwrite 2>&1 | tee log.snappyHexMesh


A hostfile is a must here without which the mpirun command would fail.

Why is this true here but not below?

Rather than try to support multi-node in the demos, I think it would be better to just add the disclaimer that they are prepared for single node use cases, but could be extended to multi-node cases. If you submit this job via SLURM you wouldn't need the complication of a hostfile

As this stands, I don't think it would work would it since there is no hostlist file?

Output file should be removed

OpenFOAM/bike_OpenFOAM8.sh

+surfaceFeatures 2>&1 | tee log.surfaceFeatures
+blockMesh 2>&1 | tee log.blockMesh
+decomposePar -copyZero 2>&1 | tee log.decomposePar
+mpirun -np $NP -ppn $PPN -hostfile hostlist snappyHexMesh -parallel -overwrite 2>&1 | tee log.snappyHexMesh


Suggested change

mpirun -np $NP -ppn $PPN -hostfile hostlist snappyHexMesh -parallel -overwrite 2>&1 | tee log.snappyHexMesh

mpirun -np $NP --oversubscribe snappyHexMesh -parallel -overwrite 2>&1 | tee log.snappyHexMesh

Yes, I have removed this in my latest script which @laraPPr is still testing. Her next commit should make things clear.

In Satish script for version 11 it is changed to this mpirun -np $NP -npernode $PPN snappyHexMesh -parallel -overwrite 2>&1 | tee log.snappyHexMesh. And that one now works correctly. I'm also less inclined to change this one because it still does something and is only their for the OpenFOAM in the pilot repo.

I don't really have a problem with this (since it will soon be lost to history anyway), but the file hostlist does not exist as far as I can see, so it really does nothing (or is it just a workaround for the use of -ppn?).

Actually -ppn is deprecated and -npernode is to be used instead with mpirun. Indeed the hostlist thing didn't make any sense to me so I also removed it as @ocaisa did. We can also get rid of --oversubscribe option and just declare that one needs to have at least 8 cores ( I would say we even need more) to run this script.

Can we change OpenFOAM8.sh to OpenFOAM_v8.sh and OpenFOAM_11.sh to OpenFOAM_v11.sh?

boegel · 2024-05-01T17:14:28Z

There's a lot going on in this PR, and there may be some parts in the current demo script that isn't fully correct.

Rather than trying to fix all problems in one go, we should try and get the minimal things done so the OpenFOAM demo can be run using the OpenFOAM installations available in software.eessi.io.

This demo is by no means meant to be a perfect example of running OpenFOAM, so in the short term it's fine if some of the substeps aren't currently doing what they should be doing. The main thing is that we can show people that the OpenFOAM installation provided by EESSI runs (not that we're experts in OpenFOAM).

So, perhaps we should open a separate PR first with the minimal work to do to get the OpenFOAM demo running with software.eessi.io, and open an issue with an overview of the problems to fix?

Tested with software.eessi.io and worked just fine

As a side point, on 4 cores I actually got an MPI error from snappyHexMesh, which made me notice that we don't actually check the return codes before proceeding to the next step.

Having said that, I agree with @boegel that we should just get this merged and worry about tweaking the scripts later (or never 😛 ).

Oh yeah, we do not check the error codes from the previous steps at all. :D Btw what was the error. I am curious. :)

Ok So I now remove the --oversubscribe flag everywhere and I added it to the run.sh script. And also remove the -hosfile flag form the bike_OpenFOAM_v8.sh script.

@ocaisa is it now ok? Or should I change something else?

That looks like a segfault due to memory limit?
