I think Ralph and Gilles covered most everything, just let me emphasize a few
things:
- MTT is simply an engine for running tests and gathering results. Nothing
more.
- MTT actually only includes a trivial test suite for MPI ("hello world" and
"send a message around in a ring").
- In the Open MPI community project, we have a closed SVN repo for our
convenience that includes a whole pile of test suites that we run via MTT.
It's a close repo because we don't own the redistribution rights to most of the
test suites (e.g., NetPIPE, IMB, OSU, ...etc.).
- You absolutely can download these test suites yourself from the greater
internet and run them via MTT. There is nothing magical about our closed SVN
repo; it's purely for our own convenience.
- The MTT web reporter we have at http://mtt.open-mpi.org/ is for us to monitor
the development of Open MPI itself.
I've seen other admins do what you're proposing (use MTT for MPI/health
checking of your cluster). While there's a bit of a learning curve, MTT is
actually pretty great at that kind of stuff -- it can run
dozens/hundreds/thousands of tests in an automated fashion and then report the
results to a central location (e.g., email, file, and/or your own internal
instance of the MTT database/web reporter).
One other piece of information that may be helpful: a key piece of knowledge
that we learned while developing MTT is that every organization wants to do
their testing differently. That's why there's so many CLI and configurable
options to MTT.
Hope that helps!
