[mpich-discuss] How codes are distributed?

[Jierui XIE]

Hello,

I am confused by a simple question. Hope someone can give me some hints.
When run mpiexec -n x program,  I am assuming that  the MPI will
distribute x processes to multiple machines.

Does it mean that one copy of the program would be copied to each machine??
Is this done by the process manager (e.g., mpd) on each machine?


Thanks.
