Hi,
 Did "mpiexec -n 2 hostname" work ? Is your machine 32-bit or 64-bit (The 32-bit installations are provided with pre-compiled sample MPI programs that you can try, c:\progra~1\mpich2\examples\cpi.exe OR you can download https://svn.mcs.anl.gov/repos/mpi/mpich2/trunk/examples/cpi.c and try it)?

Regards,
Jayesh

Hi, Very thanks for your response. MPI is an admin user. I intall
MPICH for only an user because a teacher give me this tip.
When mpiexec prompts for the username I press the enter key, and then
I write the password.
The system response to me:
job aborted:
rank: node: exit code [: error message]
0: User-PC: -1073740777: process 0 exited without calling finalize
1: User-PC: 123
I do not have in my team who has installed/used MPICH2, I sorry.
I will thanks any help.
