You can specify various switches on the mtt command line (see "mtt --help").

You can do something like: mtt --mpi-get --mpi-install --test-get --test-build --file ...whatever... --scratch ...whatever... This will download the MPI, install the MPI, get any test sources, and build them all against all the MPI's. Alternatively, you can do: mtt --no-test-run --file ... --scratch ... Because really you want to do everything *except* run the tests (right?). The only problem with this is that MTT does not yet support chaining well; so there's no real notification that the builds have all finished other than the mtt client finishes. > How to I tell the tests what branches to iterate over and where they are > located? Right now, MTT will do everything in the INI file -- you can't say "only do MPI installs A, B, and C" (and assumedly skip some other sections, such as D, E, and F). So it would probably be a PITA, but you could have different INI files with different configurations if you need finer-grained control. > The script I am trying to create would essentually do the following: > srun -N 1 -b mtt-build-phase > wait for it to complete > srun -N 16 -b mtt-testing-phase > > or something to that effect so we don't allocate all 16 machines and let > them idle while the tests are building. Yes. The only bummer is that we currently provide no assistance on the "wait for it to complete" step. :-\ -- Jeff Squyres Server Virtualization Business Unit Cisco Systems
