[mpich-discuss] Problem with MPICH2 v1.0.8 on WindowsXP

[Jayesh Krishna]

 Hi,
  You need to run an MPI job as a user. So you can do either one of the
following,

# 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".

# 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).

  Let us know if it works for you.

(PS: Or if the machines are part of a domain you can register a domain
user to run your MPI job.)

Regards,
Jayesh

Hi,
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.
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.
