Hi All

I am currently trying to run the nwchem_openmpi executable for linux platforms (CentOS 7.1 in my case) in parallel.
I am using the nwchem-openmpi-6.6.27746-22.el7.x86_64 package
I have installed the mpirun (Open MPI) version 1.10.0 and am executing with the command:

mpirun -np 2  nwchem_openmpi geo.in > geo.out
I get the following error:
[Cuba:04638] [[INVALID],INVALID] ORTE_ERROR_LOG: Not found in file ess_env_module.c at line 367
[Cuba:04582] tcp_peer_recv_connect_ack: invalid header type: -882573312

geo.out:
-------------------------------------------------------
Primary job terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpirun detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

Process name: [[52069,1],1]
Exit code: 1
--------------------------------------------------------------------------

Am I using the correct versions/syntax for parallel execution?
What version of OpenMPI are the nwchem_openmpi executable compiled with?
