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

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
