Dear Open MPI users,
I am using the following system
CentOS release 6.6
Rocks 6.2
I have been trying to install openmpi-3.1.3.
After installing it, in the example folder if want to test run I got the
following error
I run command mpirun -np 1 hello_c
[user@chimera examples]$ mpirun -np 1 hello_c
Doing the fork/exec with an environment that omitted the variables whose
names started with either 'OMPI' or 'PMIX' did the trick.

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
