Hi Folks,
   I am in the process of converting a HUGE parallel application
from PVM to MPI using ch_p4 as the device. The typical way
of running a MPI application is to use mpirun and specify the
number of parallel processes, for example
     mpirun -np 5 test  ( where test is the application)
Instread of just one executable, I prefer to have more than one
executable that comprises the whole application ( primarily
to manage the code efficiently). so basically I would like to
use mpirun in the following way
     mpirun -np 2 test1 -np 3 test2 ( where both test1 and test2
                                                                    togather
form the application)
 I know that mpirun doesnt provide for such a capability directly.
So, I was wondering whether any one has tweaked the mpirun
shell script to provide for such a capabiliy.

Thanks in advance

Vijay
