I do not thing there was any conclusion here - this is even true when one is not worrying about FT. What do you do when mpirun does not give you the number of process you asked for ? Before MPI_INIT we are not guaranteed to have more than a single "process".

Is there anything else from this ticket that we would find useful before killing it? For example, all of the text we have about MPI_INIT in ULFM is in an advice to implementors. Should we move anything to normative text?

>> This ticket specifies the behavior of the MPI library after a during MPI_INIT. Basically, if there is a failure during INIT, the library should return an appropriate return code and calling any other MPI function (with a few exceptions) is erroneous and will trigger the error handler for MPI_COMM_WORLD, which by default is MPI_ERRORS_ARE_FATAL and cannot be changed in this instance.
