Sure:
mpirun --np 3 mpi_app1 "app1_args" : -np x mpi_app2 "app2_args" : -np
y mpi_app3 "app3_args"

Dear all,
current implementation of mpirun starts the executable in different
nodes. For some reason I need to start different MPI applications
across nodes and I want to use MPI to communicate among these
applications. For short I want to breakdown the SPMD model,
something like:
mpirun --np 3 mpi_app1 "app1_args", mpi_app2, "app2_args", mpi_app3,
"app3_args"
Is it possible to have this kind of behavior with the current
implementation of mpirun?
if not... it's implement it via changing the mpirun and/or mpiexec
routines or does it implies radical changes to the entire Open MPI
library?
regards, Simone
