Re: [MTT users] Using mtt For Performance Testing Only

[Jeff Squyres]

In general, MTT is just an engine for running stuff.  We tend to use MTT 
running lots of MPI correctness and performance tests.  So yes, you could use 
MTT to run your chemistry code over varying numbers of nodes.  MTT might be a 
bit of a big tool for that, but if you have no other infrastructure for this 
kind of scripting, it may be just the ticket for your needs.

[MTT users] Using mtt For Performance Testing Only

[Jon Forrest]

I have a new IB-based cluster. I'm not sure
if the IB is running correctly. One way I thought
of to test IB is to run MPI tests. mtt looks
like it can do this, but it also does a whole
lot more that I'm not interested in.

So, I'm wondering if it's feasible to run
mtt as only a performance testing tool, not
as a build test tool. In particular, I was
thinking I could modify the
ompi-core-perf-testing.ini file to just
test a previously installed version of ompi.

By the way, I tried to read the archives for
this list, which the mailman page says are
in http://www.open-mpi.org/MailArchives/mtt-users/
but going there results in a "Not Found" error message.

Cordially,
