Expression Templates Revisited
by Klaus Iglberger
From the talk description:
Since their invention in 1995, Expression Templates (ETs) have proven to be a valuable tool for many C++ template libraries. Especially numerics libraries quickly embraced them as salvation for the performance deficiencies of standard C++. This reputation as performance optimization...

C++ SIMD parallelism with Intel Cilk Plus and OpenMP 4.0
by Georg Zitzlsberger
From the talk description:
Performance is one of the most important aspects that comes to mind if deciding for a programming language. Utilizing performance of modern processors is not as straight forward as it has been decades ago. Modern processors only rarely improve serial execution of applications by increasing their frequency or adding more execution units.

While we wait for CppCon 2015 in September, we’re featuring videos of some of the 100+ talks from CppCon 2014. Here is today’s feature:
The Canonical Class
by Michael Caisse
Summary of the talk:
It was a simpler time. A period in which every college student and learn-C++-in-a-weekend duffer could write a class with the assuredness that it would behave as desired when assigned and copied. There was a check list. Complete the checklist, add some domain specific behaviour, bake in the regression oven, and you were done.
Enter C++11 with its fancy new use of the delete keyword, additional applications of explicit, rvalue references, and some perfect forwarding. How are you to write a "simple" class? Should you include a swap? What does movable mean and are there expected semantics? When is the noexcept specifier used?
During this session we will explore the boilerplate of a C++11 class. The session will touch on rvalue references, move semantics, perfect forwarding, explicit, noexcept, initializer lists, and more as it applies to producing the desired semantics for our classes and structs.

Generic parallel programming for scientific and technical applications
by Guntram Berti
From the talk description:
Technical and scientific applications dealing with a high computational load today face the challenge to match the increasingly parallel nature of current and future hardware. The talk shows how the increased complexity of software can be controlled by using generic programming technologies. The process and its advantages are introduced using many concrete examples...

One of the lesser-known features of C++ templates.
Providing Explicit Specializations for Non-Template Members of Class Template
by Pavel Frolov
From the article:
C++ is full of surprises (albeit not always good ones
. It is a well known fact that you can provide explicit specializations for function templates and class templates. But it was a total surprise to me, that you can provide explicit specializations for non-template members of class template without specializing the class template itself!

The C++ Memory Model
by Valentin Ziegler
From the talk description:
The C++ memory model defines how multiple threads interact with memory and shared data, enabling developers to reason about concurrent code in a platform independent way. The talk will explain multi-threaded executions and data races in C++...

Pruning Error Messages From C++ Template Code

From the talk description:
Many template libraries are regarded with ambivalent feelings by developers: On the one hand, such libraries can offer wonderful functionality. On the other hand, they are dreaded for the sheer amount of error messages spilled out...

A solution to generate code for CUDA and OpenCL with C++:
Generating OpenCL/CUDA source code from C++ expressions in VexCL
by Denis Demidov
From the talk description:
VexCL is an opensource C++ vector expression template library for OpenCL/CUDA. It has been created for ease of GPGPU development with C++ and provides convenient and intuitive notation for linear algebra operations, vector arithmetic and various parallel primitives.

The latest version of Edouard Alligands talk on Multiplatform development with C++:
by Edouard Alligand
From the talk description:
C++ is a multiplatform language, yet many difficulties arise when you want the same code to compile properly and function identically on different platforms. If you put aside the obvious system programming related obstacles, and the differences you might have between compilers (especially when it comes to supporting C++11 and C++14), you come to the surprising conclusion that what is truly hard is all the “little things” you didn’t anticipate.
