Great !!

Great, that seems to fit in the meeting. You may be interested in
Friday morning especially, as it is the only time that we'll be able
to fully dedicate to general C++ techniques. The rest of the meeting
will have to revolve around Eigen per se. At least porting Eigen to
XLC is something that we could work on together, and usage of Eigen in
scientific computing is something worth dedicating some time!

That's very interesting, but a huge topic that we won't have time to
touch: we haven't started parallelizing and won't be able to until 3.0
is out.

Yes, this is very interesting. Keeping in line with the organization
of this meeting, since the number of attendees is very low, would you
agree keep your presentation to the bare minimum (say 15 minutes) and
then instead we'd discuss things in more detail in an informal
discussion? This seems to work better for such a small group of

I have reorganized Saturday to fit this:

As you can see I have moved all the talks to the morning, so that
afterward everyone can hack in small groups on various topics. The
idea is that the morning's talks give us ideas of stuff to hack on

Yes, of course! One hacking group could spend some time to port Eigen to XLC.

We are still flexible as you can see, and I am really glad that you
can come. I am proposing to fit your talk and XLC porting in the
Saturday, tell me if that's OK. Again, you may be interested at least
in Friday too.

Hauke should be especially happy that you come, as you bring the
number of non-French-speakers up to 2 !!
