Hi Peter,
The WMI worked for you, that's great. Was it difficult for you to
configure everything?
For the hanging problem, it's quite similar to another thread:
http://www.open-mpi.org/community/lists/users/2012/01/18128.php
I wasn't able to solve that one yet, it's a complicated one. But the
easy solution is to switch the send and recv sequence for root process.
Could you please have a try on that?

Running my command MPIHello still does not work across nodes; I
believe there is a MPI communication problem between the processes,
ie. MPI_Send/Recv. It worked with 2 processes but not 4. How do I go
about resolving that? Is there a problem with the build settings of my
executable?

on 2 EC2 windows instances
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://msdn.microsoft.com/en-us/library/aa393266%28VS.85%29.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

When I run across two hosts, the executable is launched on both
instances but the process hangs:

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.
