Subject: [OMPI users] Getting MPI to access processes on a 2nd computer.
From: VimalMathew_at_[hidden]

Hi,

 

I'm trying to run an MPI code using processes on a remote machine.

I've connected the 2 machines using a crossover cable and they are
communicating with each other(I'm getting ping replies and I can access
drives on one another).

 

When I run mpiexec -host system_name MPI_Test.exe, I get the following
error:

 

C:\OpenMPI\openmpi-1.6\build\Debug>mpiexec -host SOUMIWHP4500449
MPI_Test.exe

connecting to SOUMIWHP4500449

Could anyone tell me what I'm missing?
 
I've configured MPI on VS Express 2010 and I'm able to run MPI programs
on one system.
On the other computer, I pasted the MPI_Test.exe file in the same
location as the calling computer.
 
Thanks,
Vimal
