[MPICH] MPICH2 1.0.6 inder Windows without DOMAIN

[Jayesh Krishna]

Hi,
 
1) You do not need to install mpiexec (you only need to install smpd) to use
it.
2) Try specifying a higher number of iterations (say 1000) when running
cpi.exe.
3) Have you installed the windows version of MPICH2 from the installer ? (Or
have you compiled MPICH2 under cygwin ?)  

Regards,
Jayesh

The problem is they are no way to register and validate user/pass because
mpiexec is it not install
