Hi OpenMPI people,
In the attached file is all the info (as simple as I
could reproduce it) of what I think is a bug.
The basic idea is that in a sigle processor debian
machine, only TCP messaging, 1.1.2 and previous abort
in the sample program during MPI_Barrier when run with
three processes (more fail too but unpredictable).
My best guess is that PtoP messaging is interfering
with collective messaging.
Thanks for OpenMPI !
JLQ.
