Unfortunately there's not a lot we can do. If you send a number that takes 33 bits to represent to a value that only holds 32 (or 31) bits, Open MPI can't do anything magical. Whenever you need to talk across a network to an unknown peer, fixed-width types are likely going to be your simplest solution. And yes, that means you might have to do some casting (or let the compiler do automatic up-conversion for you). :-\ That's still likely a more general solution, and have fewer unexpected corner cases in the future. -- Jeff Squyres jsquy...@cisco.com _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
