Hello everybody,

I now started to test the mvapich 3.0b build. It was compiled on Rocky
Linux 9.1 with slurm 23.02.2 and gcc 11.3.1. See at the end of email for
mpichversion output.

When I try to start a simple mpi hello world with srun --mpi=pmi2
I see an error messages concerning PMI and a segfault, see also at the 
end of the email. The same mpi hello world source code using the same 
srun --mpi=pmi2 invocation (but obviously different binaries) works fine
with mvapich2 2.3.7, mpich 4.1.1 and openmpi 4.1.5.

Should I try another launcher, e.g. hydra by not setting --with-pm and
--with-pmi ? Would the hydra launcher be able to communicate wth slurm,
though ?

Best Regards

Christof
