Multiple programs in one application

Hi, is there a way with MPICH-GM to run multiple programs in one
application? For example, with LAM's MPI you can define different 
programs using an "appfile" with the -v switch (mpirun -v appfile) 
where appfile:

        {amager:ingrid:305} cat appfile
        n0 hello-ping
        n0-1 hello-pong
        {amager:ingrid:304} mpirun -v appfile


or with ANL's MPICH you can define different programs using the "procgroup 
file" defined with the -p4pg switch (but here you can provide different 
command line argument), i.e:

        {amager:ingrid:366} cat pgfile
        amager 0 /net/hp20/ingrid/MPI/MPICC/hello-ping
        anholt 1 /net/hp20/ingrid/MPI/MPICC/hello-pong
        anholt 1 /net/hp20/ingrid/MPI/MPICC/hello-ping
        bogoe  1 /net/hp20/ingrid/MPI/MPICC/hello-pong
        {amager:ingrid:365} mpirun -p4pg pgfile programsthatrunonnode0


Any help, or suggestion is appreciated.
 
 Thanks,
