Hello all The wiki page has been updated with the latest test results from a new branch that implemented inbound collectives on the modex and barrier operations. As you will see from the graphs, ORTE/OMPI now exhibits a negative 2nd-derivative on the launch time curve for mpi_no_op (i.e., MPI_Init/MPI_Finalize).
Some cleanup of the branch code is required before insertion into the trunk. I'll send out a note when that occurs. The wiki page is at: https://svn.open-mpi.org/trac/ompi/wiki/ORTEScalabilityTesting Ralph
