"As of Open MPI 1.1, we do support endian conversion between peers. It has not been as well tested as the rest of the code base, but it should work."

I want know only if the Open MPI v.1.1 support the endian conversion. Bye Alfonso >>from brbarret >>Actually, >Jeff is incorrect. As of Open MPI 1.1, we do support endian >>conversion between peers.
