Subject: Re: [OMPI users] OpenMpi on a windows Xp tcp network

Hi Bradi,

Yes, as you are on an XP machine, the io forwarding is not working for
Open MPI. So you won't see the remote output from the local command
windows. The only way is to direct the output into a file, for example:
mpirun -n 2 app.exe > output.txt . This will generate the output file on
remote computer under the same path where you run on local computer.
