[mpich-discuss] MPI_Comm_connect between windows and linux machines

[Jerome Soumagne]

Jayesh,

thanks again for your reply. Well, actually I was hoping to keep the mpd 
process manager, thinking about some compatibility between both process 
managers. I will build another mpich library using the smpd one.

Regards,

Jerome
