[mpich-discuss] mpi error

[Jayesh Krishna]

Hi,
 Some suggestions,

# Since your OS is 64-bit, uninstall the 32-bit version of MPICH2 and install the 64-bit version
# Try running the sample program, cpi.exe, provided with MPICH2 and see if it works
# Run your server/client program and see if it works

Regards,
Jayesh

Hi, 
I use mpich2-1.4.1p1-win-ia32, and i run the server program in command line the command is : mpiexec -np 1 server.exe 
and the error now is : 
Error while connecting to host, Aucune connexion n'a pu être Útablie car l'ordinateur cible l'a expressément refusée. (10061) 
Connect on sock (host=MOUSSA-VAIO, port=8676) failed, exhaused all end points 
Unable to connect to 'MOUSSA-VAIO:8676', 
sock error: Error = -1 
Thank you Jayesh
