[mpich-discuss] machinefile error

[Pavan Balaji]

The error you are reporting doesn't seem to be coming from Hydra's 
mpiexec. Also, is this on windows (since your executable is called cpi.exe)?

On windows the default process manager is SMPD, and you'll need to 
follow its instructions from the user guide. On UNIX, the default 
process manager is MPD for up to MPICH2-1.2.1p1. For MPICH2-1.3, we are 
changing the default to Hydra.
