<P><FONT SIZE=2> Hi,<BR>
You need to run an MPI job as a user. So you can do either one of the following,<BR>
<BR>
# Create a new user, "mpiJobUser", on both the machines and register the username/password of the user on both the machines. Your MPI jobs will be run by "mpiJobUser".<BR>
<BR>
# Create a new user, "Ondrej", on the second computer and register the username/password of the user on the second computer (Make sure that you have the same password on both the machines).<BR>
<BR>
Let us know if it works for you.<BR>
<BR>
(PS: Or if the machines are part of a domain you can register a domain user to run your MPI job.)<BR>
<BR>
Regards,<BR>
Jayesh<BR>

Hi,<BR>
No I have one user (Ondrej) on one computer, and the second (shrek) on the second computer. I can run a mpi program seperately on both machines, but they don't cooperate if I want them to compute something distributedly.<BR>
Anyway, I install virtual machines on both computer with linux and it works well. It is really not good solution, but at least I got it working...though the performance is certainly worse than if I had it naturally in Windows and not in virtual machines.<BR>
