I'm confused; why is it disastrous to have an interface in if_exclude that doesn't exist? I can see it being a problem if we don't exclude something in the list, but the other way is (in my opinion) harmless but with a useful use case...

I still maintain that it's equally disastrous if you don't exclude the correct interfaces (I lost 2 nights of MTT because of this!). > I'm not a fan of the nowarn option.

This is a good point -- I wonder what openib (and others?) do who support *_if_include and *_if_exclude notation. Do they warn / error if you specify an invalid interface? > If you need specialized arguments for some of your nodes here is what I do: > rename the binaries to .orig, and use the original name to create a sh script > that will change the value of mca_param_files to something based on the host > name (if such a file exists) and then call the .orig executable.

Remember: all the tests that are run in MTT are shared across all of us via the ompi-tests SVN repo. Are you suggesting that I alias every test in the ompi-tests SVN with a public script that you should run that should look for some site-specific MCA override param file? -- Jeff Squyres jsquy...@cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/ _______________________________________________ devel mailing list de...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/devel
