Alan,
note you do not have to use the *-ib hostnames in your host_filethese are only used for SSH, so since oob/tcp is running on your ethernet network, i guess you really want to use sm3 and sm4 host names.
did you also run the same netcat test but in the other direction ? do you run 'mpirun' on sm3 ? here are a few tests you can perform - run tcp over ethernet mpirun --mca btl_tcp_if_include 192.168.1.0/24 ...- run all 4 tasks on sm3 (host_file contains one line "sm3 slots=4") with tcp (e.g. --mca btl tcp,self)
- run with verbose oob and tcp mpirun --mca btl_base_verbose 100 --mca oob_base_verbose 100 ... when your app hangs, you can manually run pstack <pid> on the 4 MPI tasks so we can get an idea of where they are stuck Cheers, Gilles On 5/30/2017 3:49 AM, Allan Overstreet wrote:

This means that this component is either not installed or is unable to be used on your system (e.g., sometimes this means that shared libraries that the component requires are unable to be found/loaded).

There are many reasons that a parallel process canfail during MPI_INIT; some of which are due to configuration orenvironmentproblems.
