[Other] OpenMPI Infiniband fails in Open Suse 42.3

derekm · September 14, 2017, 11:51

ON open Suse 42.3 If you take the current distro version of Openmpi (1.10.6) You find that infiniband fails to work even if you installed infiniband correctly.
You will find although the distro has support for infiniband and for infiniband in openmpi it refuses to see it.
This is because opensuse in their wisdom complied openmpi with MPI_THREAD_MULTIPLE.
This feature is broken until version 2.something of openmpi and openib with MPI_THREAD_MULTIPLE is definitely not supported in openmpi 1.10 so openib never starts.

A bug has been reported with opensuse

To fix this you need to recompile openmpi.

Download openmpi-1.10.7-1.x86_64.src.rpm
from the open mpi website then
using Yast remove all of the openmpi 1.10.6 packages then:

Code:

sudo rpm -i openmpi-1.10.7-1.x86_64.src.rpm
cd /usr/src/packages/SPECS
sudo rpmbuild -bb  openmpi-1.10.7.spec --define='build_all_in_one_rpm 0'
cd /usr/src/packages/RPMS/x86_64
sudo rpm -i openmpi-docs-1.10.7-1.x86_64.rpm openmpi-runtime-1.10.7-1.x86_64.rpm openmpi-devel-1.10.7-1.x86_64.rpm

Then install OpenFOAM.
