Reply To: Segmentation fault for OpenLB 1.5
Sadly I can’t tell you anything from this output. You will need to compile it with debug symbols enabled and ideally run it in a debugger to obtain backtrace information.
Does the example run in MPI mode on your local computer? Can you confirm whether other MPI-based applications work using the exact same approach on this cluster, using the same nodes?
Do other OpenLB examples work with MPI?
For me, the example works without issues both locally and on the clusters that I have access to.
Of course there can still be problems with the code but we will need more details to find the reason.
What did you configure in config.mk? (In order to avoid confusion: It is not enough to load the modules, the compiler and parallel mode still has to be configured in the config.mk file)
