[MPICH] start mpd if it has not started

[Reuti]

Hi Raju,

if you use some scripts anyway, what about using a queuing system like 
Torque and use mpiexec from http://www.osc.edu/~pw/mpiexec or SGE which 
will start the daemon on it's own for each job (okay, not the mpd 
version but the smpd)? As a side effect this might shorten your scripts.

Cheers - Reuti
