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 !
