[ptp-dev] Open-MPI rewrite
|
Nathan,
I'm waiting for your commit before committing my changes. We are
probably hitting the same sources, e.g. ModelManager. (In fact, I would
like to refactor ModelManager into an abstract base class with separate
subclasses for each type of model.) Some of my changes are small, so I
thought that you should commit first, since it may be easy to gloss over
my many small changes during a CVS merge. If I do refactor ModelManager
without your changes being first committed, then all heck will break
loose during a merge.
If it does not seem likely that you will be committing to HEAD in
the near future, then I have two alternate suggestions.
1) Create a new branch for your work. I'll merge my changes from my
branch into your branch. When your branch stabilizes we will merge
your branch to HEAD.
2) I will merge to HEAD without your changes. Later you can commit
to HEAD, but there may be a lot of small error-prone conflicts to
iron out, and a big headache with the ModelManager refactoring.
I would prefer the first option, but if your changes are not anticipated
to be stabilized enough to commit to HEAD for a long time, then this
may not be the best option. If you have other alternatives, let me
know.
advTHANKSance,
R^2
