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

[pisoir]

Hi Bob,

Thanks for your advice. It seems that the 2nd solution would be my last 
chance. I just don't know if I want Vista running as the 2nd computer. I 
only have 1 router between the computers, so the 1st solution is not 
applicable for me. I just don't understand why the setting of mpi is so 
different and more complicated than setting mpi on linux.
