WHAT: Revamp the topo framework to be more consistent with the rest of
the code base
WHY: The code was ancient, inconsistent with the rest of the code
base, and had some latent bugs. It would actually have been
impossible to have a 2nd topo component.
WHERE: ompi/mca/topo/*, ompi/debuggers/*, ompi/communicator/*, ompi/
TIMEOUT: COB Monday, 9 Nov 2009
As discussed a few days ago on this list, I revamped the OMPI topo
framework to make it more modern / like all the other frameworks (it
was written way back near the very beginning of this project and has
barely been modified since). I fixed some latent bugs (which weren't
evident because we only have the 1 topo component -- unity) and made
the selection scheme much more consistent with the rest of the code
The code can be found here:
Attached is a patch against the SVN trunk, r22197. If no one has any
objections / suggestions / comments, I plan to commit this work by COB
next Monday, 9 Nov 2009.
This RFC has a short timeout because I expect this to not be
controversial and I already mentioned this on the list a few days ago.
