Hello preCICErs, I’ve been trying to adapt the partitioned-pipe tutorial to run as SLURM job but I’m facing issues. [NOTE: The serial execution in the original version tutorial runs without error.] I’ve a script run.sh (1.6 KB) in the case directory which takes care of the node partitioning and…

[image] nish-ant: Can you point me to some resources regarding these options? Is it something I need to take care of during preCICE installation? Yes, this is something you need to take care of yourself. What would be the best way depends a lot on how you install preCICE in Spack. In the pack…

The message Host key verification failed from the second solver sounds like a problem of tasks connecting to each other between nodes. Are you able to run other programs that do not use preCICE across several nodes?

Yes, I use OpenFOAM without preCICE and they run fine across multiple nodes. For example, here is a job running over 6 nodes: JOBID PARTITION NAME USER ST TIME START_TIME END_TIME TIME_LEFT NODES MIN_MEMOR PRIOR SCHEDNODES NODELIST(REASON) SCHEDNODES 7932235 imb-…

I was able to run the partitioned pipe tutorial with an in-house solver using Slurm a few months ago. You say you tried the steps in the guide you linked, yet still you have ./ as the exchange directory in your precice-config.xml. According to your run.sh your two solvers work in two different direc…

@Ray_Scarr Thanks for your reply. Yes, you’re right that the path of the exchange directory should have been ../. I had misinterpreted the remark about relative paths in Help! The participants are not finding each other! - #2 by Makis . However I re-ran the simulation with the correction and the erro…

Great job debugging so far and nice to see that the parallel solver dummies are helpful. That at least eliminates OpenFOAM from the equation at the moment. It could be that you have some MPI installation issues that may be two-fold. Here are some guesses: Host key verification failed: What you ob…

Thanks Alex for the suggestions. [image] ajaust: Spack’s OpenMPI recipe has an schedulers option. There are also quite some other options that might affect the behaviors (e.g. PMI, PMIX). Maybe it would be worth asking your admins about that. Can you point me to some resources regarding thes…

Got it. I will go through the documentation and reinstall preCICE.

Hello Alex, It took some time and tweaking of the spack environment but I can now run the C++ parallel solver dummy on partitioned nodes. But I am unable to build the OpenFOAM adapter and seeing messages regarding undefined symbols again, similar to the previous issue: [OpenFOAM-6 adapter] Error d…

Great that you solved it! I understand that what worked for you in the end was tweaking the Spack environment as stated above ( [OpenFOAM] Unable to run SLURM partitioned simulation - #8 by ajaust ). If that is the case, could you please mark that as the answer to this thread? Regarding building the …
