My MPI program works completely without any problem in the interactive mode, i.e. before submitting to HPC. However when I submit it with "bsub", everything works again until "MPI_FINALIZE" hangs and following error comes up:
mpirun noticed that process rank 2 with PID 8620 on node ... exited on signal 11 (Segmentation fault).
It is not for sure an error in the code because
I have commented all of the code (except MPI part) but the problem is still there. Then I think it can be from submitting the code, the bash script or compiling/linking libraries/headers.
Has anyone seen this error before? any idea to correct it?
