OpenMPI Fails to Run

[Altman, Eric]

I am trying to run MPI programs under Cygwin64 version 1.15.1-4 with OpenMPI version 1.7.5-1.  The computer is an i7 running Windows 8.0.  I do not have any issues compiling programs, but I get the following errors trying to run hello_c.exe (https://github.com/hpc/cce-mpi-openmpi-1.6.4/tree/master/examples):

$ mpirun -np 4 hello_c.exe
[fsp-eng-jfn5kn1:03900] [[63491,0],0] CONNECTION REQUEST ON UNKNOWN INTERFACE
[fsp-eng-jfn5kn1:03900] [[63491,0],0] CONNECTION REQUEST ON UNKNOWN INTERFACE
[fsp-eng-jfn5kn1:03900] [[63491,0],0] CONNECTION REQUEST ON UNKNOWN INTERFACE
[fsp-eng-jfn5kn1:03900] [[63491,0],0] CONNECTION REQUEST ON UNKNOWN INTERFACE

I have all the packages it said to load (rsh, ssh, all versions of compilers and header files).
I have tried numerous things but always get this error.  I would appreciate any help in resolving it.

Thanks.
