9208,MPI failure on big endian machines,Steve Nolen <drnuke@…>,Matthias Troyer,"On big endian machines (i.e. LLNL's Sequoia) the boost MPI implementation is broken.  When a class's version is written to a packed_oarchive, the value (an unsigned int, uint32) is written as a 1-byte integer.  The process sort of works on little endian machines where the least significant byte is being copied.  On a big endian machine, this 1st byte is always going to be zero.  I have put together a patch that explicitly converts the uint32 to a uint8 to avoid this issue.  Feedback is appreciated.",Bugs,closed,To Be Determined,mpi,Boost 1.54.0,Showstopper,fixed,"mpi, endian",
