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
