Open MPI support the full mpiexec command as described by the MPI standard. Here is an example on how to start a MPMD application (general case of heterogeneous application).

mpirun -np 1 -host host_x86 <path_x86>/application_x86 : -np 1 -host host_sparc <path_sparc>/application_sparc

hi everybody,

i couldn't find any information about how to start a mpi application
(compiled for different architectures) in heterogeneous networks using
the mpirun command included in OpenMpi. Mpich1 supports starting
different binaries with the "mpirun -arch" command. How can I start
different binaries using OpenMpi?
