Subject: Re: [OMPI devel] How to disable paffinity

You may be working off of an old version of OMPI - I updated opal_paffinity awhile ago to no longer require that a component be selected. Then you can no-build all paffinity components if you like and the system will still startup okay.

I don't believe this was moved over to the 1.4 release branch - afraid you would have to use a developer's trunk tarball or svn checkout. It -might- be in the 1.5.0 release candidates, though (I haven't looked).
