Hi EasyBuilders,

We are having problems with using the foss/2022a toolchain on some of our nodes 
with OmniPath.  The crash happens in 
/home/modules/software/OpenMPI/4.1.4-GCC-11.3.0/lib/openmpi/mca_btl_ofi.so(mca_btl_ofi_context_finalize+0x48)[0x2acdbfee9f68]
so I suspect it may have something to do with wrong MCA parameters for OpenMPI. 
 

We do not manually set any such parameters, and I have no idea what parameters 
to play with.  We are having a default installation of foss/2022a with 
OpenMPI/4.1.4-GCC-11.3.0

Do any of you experts have an idea about how to debug this, or what environment 
variables to set to get the right MCA (assuming that the MCA is indeed the 
culprit)?

It is two different codes both giving a segmentation fault during MPI_Init() or 
MPI_Init_thread(), and both work with foss/2020b but fail with foss/2022a.

With my best regards

Jakob
