Ralph,
If you plan to compare OMPI to Mvapich, make sure to take the version
1.0.0 (or above). In 1.0.0 OSU introduced
new launcher that works much faster than previous one.

Pasha

Per this morning's telecon, I have added the latest scaling test results to
the wiki:
https://svn.open-mpi.org/trac/ompi/wiki/ORTEScalabilityTesting
As you will see upon review, the trunk is scaling about an order of
magnitude better than 1.2.x, both in terms of sheer speed and in the
strength of the non-linear components of the scaling law. Those of us
working on scaling issues expect to make additional improvements over the
next few weeks.
Update results will be posted to the wiki as they become available.
Ralph
