the asynchronous library

by Christophe Henry

From the talk description:

An infrastructure library on which Boost Meta State Machine can build. This will be provided by the Asynchronous library: Active Objects, proxies, threadpools, parallelization algorithms, work-stealing, distributed programming...

The bell has tolled for rand()—Indi

An extensive article about rand(), it's replacement in C++11 and the possible future was posted last december:

The bell has tolled for rand()

by Indi

Form the article:

In their recent meeting in Urbana, the C++ standard committee took the rare step of removing several outdated facilities from (what will probably become) C++17. Most of the things removed had been deprecated since C++11, but there was one surprising item on the list: std::random_shuffle(). Its removal is a signal of a big change that has been building in the background for a while: the end of std::rand()...

CppCon 2014 Paying for Lunch: C++ in the ManyCore Age

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:

Paying for Lunch: C++ in the ManyCore Age

moderated by Herb Sutter, with Pablo Halpern, Jared Hoberock, Artur Laksberg, Ade Miller, Gor Nishanov and Michael Wong.

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Concurrency is one of the major focuses of C++17 and one of the biggest challenges facing C++ programmers today. Hear what this panel of experts has to say about how to write concurrent C++ now and in the future.

Interactive Metaprogramming Shell based on Clang

A new video from Meeting C++ 2014:

Interactive Metaprogramming Shell based on Clang

by Ábel Sinkovics

From the talk description:

Developing metaprograms is hard and painful. Templight (http://plc.inf.elte.hu/templight/) supports the development and debugging of template metaprograms, but the code has to be recompiled after every minor change and tricks are needed to retrieve useful information about the result...

Expression Templates Revisited

A new video from Meeting C++ 2014!

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

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.

Generic Parallel Programming

A new video from Meeting C++ 2014:

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...

Pruning Error Messages From C++ Template Code

A new video from Meeting C++ 2014 is uploaded:

Pruning Error Messages From C++ Template Code

by Roland Bock

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...

Generating OpenCL/CUDA source code from C++ expressions in VexCL

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.
