MPI_Iallreduce completes, and hence **before** MPI_Wait() completes,
so the behavior of such a program is undefined.

Dear all,
I have a little piece of code shown below that initializes a
multidimensional Fortran array and performs:
- a non-blocking MPI_Iallreduce immediately followed by an MPI_Wait
- a blocking MPI_Allreduce
After both calls, it displays a few elements of the input and output
buffers.

this is problem, but it's worth
checking). Grab the latest beta:

It's a very small package and easy to install under your $HOME (or
whatever).
Can you send the output of "plpa-info --topo"?

sed our tests to pass while your system fails. I'm particularly
suspicious of the old kernel you are running and how our revised code
will handle it.
For now, I would suggest you work with revisions lower than r19391 -
could you please confirm that r19390 or earlier works?
Thanks

there.
We'll report back later with an estimate of how quickly this can be fixed.
Thanks

Ralph,
I compiled a clean checkout from the trunk (r19392), the problem is
still the same.

What OM
maffinity framework makes some calls into paffinity that need to
adjust.
So version number would help a great deal in this case.
Thanks

It runs smoothly if mpi_paffinity_alone is set to 0. For a number
