Hi,
Please provide us the following logs,
# Stop any running instances of smpd using the command "smpd -stop".
# Start smpd in debug mode and collect the debug log using the command, "smpd -d > smpd.log"
# Launch your job in debug mode and collect the debug log using the command, "mpiexec -verbose -n 2 cpi.exe > mpiexec.log"
# Stop smpd in debug mode (Ctrl-C)
# restart smpd using the command, "smpd -start"
# Provide us with mpiexec.log and smpd.log (and any error output)
Regards,
Jayesh

Hi,
I am sure my version of windows is 32-bit, I installed it and I checked
it as well.
Is it possible to set that mpiexec (or smpd) is running only on one core?
Thanks
Regards,
Ladislav Huraj
