    Is there a bug list available for IBM's implementation
of MPI for the SP-2?  (I *don't* mean MPICH.)  I am having
a weird problem with sends never completing, and I would
like to make sure I'm not running into some known problem
in IBM's software before I spend a month looking for
a bug in my code.

    I know I could just use MPICH, and the code runs fine
under MPICH, but I worry that it *could* be a bug or a violation
of the MPI standard (also, IMHO, a bug) in my code that 
just doesn't cause a problem when using MPICH.  (E.g., the
MPI_Send/MPI_Recv "potentially unsafe code" does deadlock
under IBM's version for messages > 4K, but not under MPICH.)
