Lightning talks

Dear C++ Community,
in our next meeting we will have some lightning talks. The idea is not to have one full length talk, but rather to have 4 to 6 small talks around 10 to 15 minutes about different topics and aspects of C++.


And therefore we need you. So, if you have played around with some new feature, or you made a small demo, or you want to tell us about this new cool library you recently discovered, you are cordially invited to give give a lightning talk at our next meetup. Just contact us.


So far we have these confirmed talks:
• Martinho Fernandes - Unicode in C++11

• Fabio Fracassi - tba.
• Andre Bergner - tba.
• Karsten Ahnert - Pimpl techniques
• You - ?

Our next meeting will take place on 15. April in the C-Base. As usual our meeting starts at 7.00 p.m.

March Meeting

Hi,
at our March meeting (18.3. in the C-Base) we will have Peter Gottschling from Dresden with a talk about productive scientific computing in general and the matrix template library (MTL)  in detail, see below. Peter is the head of the german delegation in the  C++ standard commitee and he is very well known for his contributions to the scientific programming community. As always, we meet at 7, the talk starts at 8.
 


Abstract:

The Matrix Template Library v4 (MTL4) has been proven to provide high
performance on different platforms while -- maybe even more
importantly -- allowing for high productivity in the development
process. The intuitive notation provides an easy entry level and quick
programming progress while scientists do not need to waste their time
with deep technical details. We will demonstrate how applications
can be written as easily as in Matlab. Multi-threading acceleration
can be enabled by compiler flags. The CUDA version of MTL4 is designed with
the goal to enable the same productivity on GPGPUs while allowing for
maximal performance. MTL4 has the same interface on GPUs as on
CPUs so that all applications can use CUDA without
program modifications. The talk shall give an overview of intuitive
MTL4 programming and an easy way for cross-platform portability.

January meeting

Hi,
at our January meeting we will have a talk about CMake by Manuel Herrmann and Norbert Schultz. More details will follow.

We will meet on 21.th of January, at 7.00 p.m. in the C-Base. The talk will start at 8.00 p.m.

C++ User Group Meeting December

At our December meeting, Valentin Ziegler from think-cell will talk about the C++11 memory model.
The C++ memory model defines how multiple threads interact with memory and shared data. This model enables you to reason about concurrent code in a platform independent way.
First, Valentin will discuss multi-threaded executions and data races in C++, and why you need to be aware of optimizations performed by compiler and hardware.
Then he will show how consistency is achieved using locks and atomic operations. Finally, Valentin will take a close look at the different memory orders for atomic operations, even those you should never use.

You can find the Slides for this talk in our github: CppMemoryModel_think-cell.pdf
Additionally we promised you some links:

• Interactive Memory Model
• Mappings of atomics to assembly instructions

C++ User Group Berlin Meeting November

Hello Boys and Girls,
our next C++ user group meeting is coming closer. This time we have two talks: Martinho Fernandes will give a talk about the "Rule Of Zero" - a very important topic especially in the light of C++11. Furthermore, Fabio Fracassi from think-cell will give a short trip report about the C++ standarization meeting in Chicago.
We hope to see you all in the C-Base!

The meeting will be on 19.th of November in the C-Base. We start at 7 p.m.

October Meeting

Dear C++ Lovers,
the next meeting is our first anniversary and we have a special guest from Düsseldorf: Jens Weller. Jens is organizing MeetingC++ - the largest C++ conference in Europe - and he actively reports about C++ on Twitter and on his blog. On our meetup he will speak about Qt5 and the multimedia framework.
We hope to see you all there!

September Treffen

Liebe C++ Community,

am Dienstag den 17.9. findet unser nächstes Treffen statt. Es geht um 7 Uhr los und wir treffen uns wieder in der C-Base.

Update: Richard Guillemot wird in Talk eine C++ Fallstudie präsentieren: Solving 1D PDE with the Crank-Nicholson Scheme.  Richard Guillemot is IT Developer and Quantitative Analyst and provides modeling, simulation and analytical skills as consultant."
