I wanted to know what folks thought about adding a ping-pong performance
test to the examples directory?
Pros: This would facilitate performance sanity testing by OMPI users --
particularly MPI neophytes. It would add something to the examples
directory with a performance orientation. It would give us
(devel_at_ompiorg) a known quantity when trouble shooting performance with
users. It could conceivably raise OMPI visibility in the MPI world. It
could be a stepping stone to developing a more complete set of MPI
performance sanity tests with time.
Cons: There are already many performance tests. We shouldn't be
replicating what others do, but should be leveraging what they do.
Other existing tests are relatively easy to use and already familiar to
