OS: Centos 7
Infiniband Packages from OS repos
Mellanox HCA
Compiled openmpi 1.10.7 on centos7 with the following config
./configure --prefix=/usr/local/software/OpenMPI/openmpi-1.10.7
--with-tm=/opt/pbs --with-verbs
Snippet from config.log seems to indicate that the infiniband header files were
located
btl_openib_CPPFLAGS=' -I/usr/include/infiniband'
common_verbs_CPPFLAGS=' -I/usr/include/infiniband'
oshmem_verbs_CPPFLAGS=' -I/usr/include/infiniband'
Everthing seems to have compiled correctly, but when I try to run any program
using mpirun I am receiving the following error:
mpirun -np 8 ./a.out
--------------------------------------------------------------------------
[[18431,1],2]: A high-performance Open MPI point-to-point messaging module
was unable to find any relevant network interfaces:
Module: OpenFabrics (openib)
Host: host-name
Another transport will be used instead, although this may result in
lower performance.

help-mpi-btl-base.txt / btl:no-nics
[:13959] Set MCA parameter "orte_base_help_aggre
gate" to 0 to

I am unsure as to where to go from here. Any help would be appreciated as to
how to troubleshoot this issue.
Thank you,
Sajesh
