Hello, I am trying to run OpenLB in a highly-parallelized HPC environment using mpirun. I can run the sample case I have prepared across 8 cores, but to achieve higher speeds, I would like to increase to up to 50 cores. However, when I try to run the case with such high parallelization, I am getting the following error (stderr):
[dc006bdb2618:03053]  ./roomspec(+0x23ace)[0x559446d95ace]
[dc006bdb2618:03053] *** End of error message ***
[dc006bdb2618:03064]  /lib/x86_64-linnux-gnu/libc.so.6
[dc006bdb2618:03064]  ./roomspec(+0x23ace)[0x555660caeace]
[dc006bdb2618:03064] *** End of error message ***
I cannot determine at all what is causing this error, so I would like to request, could anyone give any insight as to what this error message is indicating and any possible root causes?
