Hi Gilles,
Thanks for the suggestion.
If I do exclude sm in the command line in the following way it seems to
work.
@chimera examples]$ mpirun -np 1 --mca btl ^sm hello_c
libibverbs: Warning: no userspace device-specific driver found for
/sys/class/infiniband_verbs/uverbs0
libibverbs: Warning: n
Srijan,
The logs suggest you explicitly request the btl/sm component, and this
typically occurs
via a openmpi-mca-params.conf (that contains a line such as btl =
sm,openib,self), or the OMPI_MCA_btl environment variable
Cheers,
Gilles
