The next MPI Forum meeting is April 28-30 in Chicago, IL. Following
what we have been doing for the past 2 meetings, this means that the
OMPI meeting will be 1-5pm US Central time on Wednesday, 30 April.
We could probably have a teleconf portion for this, because I would
imagine that this kind of discussion (perhaps with some hands-on and/
or some brief slides) could translate well to a remote audience for
those who don't want to travel just for a 1 afternoon meeting.

Great!
I don't have a religious preference between the options (hg vs git
vs ??),
but think we should definitely move away from svn.
Someone mentioned discussing this at some upcoming meeting? Could
you send
around some info on this, since (ahem) some of us at least are -not-
involved in the wonderful MPI Forum, and have no idea when this
might be
taking place???
Thanks
Ralph

Cool -- thanks Roland!
For anyone who wants to play with the entire history of OMPI in git
(as of last night or so -- this git repository is *not* being kept in
sync with SVN), I cloned the tree that Roland created and put it
here:
http://www.open-mpi.org/~jsquyres/unofficial/ompi.git
So you can:
git clone http://www.open-mpi.org/~jsquyres/unofficial/ompi.git
And then work with local git operations from there.

<http://utsl.gen.nz/talks/git-svn/intro.html> has some interesting
info about svn->git conversions (and svn vs. next-gen distibuted
systems in general).
Also, out of curiousity I tried doing
git-svn clone --stdlayout http://svn.open-mpi.org/svn/ompi/
and it seemed to work fine (git-svn is part of the main git
distribution). The only obvious thing missing is that you would
probably want to set up an author file for a real conversion, so
that
you get real names instead of just "jsquyres". It took a while to
run, mostly because it has to grab each svn changeset one by one.
The interesting thing is that a checkout of the current ompi tree
seems to be about 37 MB, while .git directory of my repository,
which
has the entire history of all branches of the svn repository plus
1.6MB of svn metadata is 36 MB. And git can do fun stuff like
git diff v1.1..v1.2
in half a second (it generates a 274858 line diff). It can generate
the full 116320 line (11164 commit) log of the trunk in .3 seconds.
Jeff, if you want to see the repository, it is in
/data/home/roland/ompi.git
Feel free to make it available however you want (it's your data of
course).
- R.
