All,
just a short summary of what happened last week at the deal.II workshop
in Heidelberg:
1/ As always, lots of cool applications based on deal.II were shown.
2/ 2.5 days were reserved for code jams where we all sit around the
table and code. I hope that everyone who stayed around for this got
something out of it and had the opportunity to ask questions and get help!
3/ We hatched a number of plans for the nearer and farther future, with
a good amount of work already done on branches at the workshop:
- Matthias Maier has started working on converting the build system to
cmake
- Baerbel Janssen has continued to work on a scheme to evaluate second
derivatives of shape functions and solutions without finite
differencing and then also to compute higher derivatives
- Timo Heister is working on an overhaul of the way we make sure
matrix and vector elements are communicated across processors in
parallel computations
- I have started to work on a scheme where we will have a dedicated
class that represents component masks, rather than using
std::vector<bool> as we currently do
- Practically everyone has helped with a branch on which we convert
every unsigned int that represents global indices of degrees of
freedom to a custom data type. This helps both the readability of
code but also allows us to use data types that can support more than
4 billion unknowns for large computations.
4/ There were ~175 commits to the svn repository between last Monday and
now that are related to what we've been discussing there. Expect good
things to happen when these branches are finally merged!
Finally, I would like to use the opportunity to say thanks to the
organizers -- Baerbel Janssen, Timo Heister, Matthias Maier, Thomas Wick
-- who have put this all together so expertly. I'm sure I speak for all
that this was great and that we really appreciate the time and work you
have put into this!
Best
W.
PS: The way it looks there will be funds for similar workshops in the US
in 2013 and 2015. I am looking forward to meeting some of the US-based
people then!
