All, With some help, I managed to build an Open MPI 4.0.0 with:
./configure --disable-wrapper-rpath --disable-wrapper-runpath --with-psm2 --with-slurm --enable-mpi1-compatibility --with-ucx --with-pmix=/usr/nlocal/pmix/2.1 --with-libevent=/usr CC=icc CXX=icpc FC=ifort The MPI 1 is because I need to build HDF5 eventually and I added psm2 because it's an Omnipath cluster. The libevent was probably a red herring as libevent-devel wasn't installed on the system. It was eventually, and I just didn't remove the flag. And I saw no errors in the build! However, I seem to have built an Open MPI that doesn't work: (1099)(master) $ mpirun --version mpirun (Open MPI) 4.0.0 Report bugs to http://www.open-mpi.org/community/help/ (1100)(master) $ mpirun -np 4 ./helloWorld.mpi3.SLES12.OMPI400.exe It just sits there...forever. Can the gurus here help me figure out what I managed to break? Perhaps I added too much to my configure line? Not enough?
