I have no problem with the option --enable-heterogeneous, when I build Open MPI, but Open MPI will not work in a heterogeneous environment with little and big endian machines, while LAM MPI can handle such environments. You wanted to solve this problem. https://svn.open-mpi.org/trac/ompi/ticket/3430 I would appreciate if you wouldn't remove this option. Kind regards Siegmar
