Hi Peter,
The Open MPI potentially uses WMI to launch remote processes, so the WMI
has to be configured correctly. There are two links talking about how to
set it up in README.WINDOWS file:
http://msdn.microsoft.com/en-us/library/aa393266(VS.85).aspx
http://community.spiceworks.com/topic/578
For testing whether it works or not, you can use following command:
wmic /node:remote_node_ip process call create notepad.exe
then log onto the other Windows, check in the task manager if the
notepad.exe process is created (don't forget to delete it afterwards).
If that works, this command will also work:
mpirun -np 2 -host host1 host2 notepad.exe
Please try to run the above two test commands, if they all works you
application should also work. Just let me know if you have any question
or trouble with that.

I am a new comer to Open MPI.
I have spent the last day trying to diagnose why a "hello world" MPI
application compiled with OpenMPI v1.6.1 (64 bit) hangs when run on
two EC2 Windows instances. I note they are running on different
subnets so I'm using the mca btl_tcp_if_include 10.0.0.0/8 parameter.
My two hosts are 10.242.73.81,10.116.114.238. I've placed the
executable in the same path on both machines.
Diagnostic info requested is attached along with sample application
source.
When I run two processes on one instance -- the command succeeds:
C:\mpi\exe>mpiexec -n 2 -host 10.242.73.81 --mca btl_tcp_if_include
10.0.0.0/8 MPIHello.exe
WE have 2 processors
Hello 1 Processor 1 at node AMAZONA-BMCKVD6 reporting for duty
When I run across two hosts, the executable is launched on both
instances but the process hangs:
C:\mpi\exe>mpiexec -n 4 -host 10.242.73.81,10.116.114.238 --mca
btl_tcp_if_include 10.0.0.0/8 MPIHello.exe

Re-running with debug:
C:\mpi\exe>mpiexec -n 4 -host 10.242.73.81,10.116.114.238 -d --mca
btl_tcp_if_include 10.0.0.0/8 MPIHello.exe

I'd appreciate any guidance to getting this example to run on two
instances on disparate subnets on Windows Server 2008 R2.
Thanks in advance for your help.
