CppCon 2014 Generic Programming with Concepts Lite, Part II--Andrew Sutton

By Adrien Hamelin | Mar 25, 2015 08:00 AM | Tags: experimental advanced

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:

Generic Programming with Concepts Lite, Part II

by Andrew Sutton

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

In this talk, I will give an overview of the Concepts Lite language extension for C++ and present examples of its use in design and implementation of real-world generic libraries. Concepts Lite provides the ability for programmers to directly state constraints on template arguments as part of the template declaration. These constraints are predicates which determine whether or not a template argument can be used with that template. Constraints are checked by the compiler at the point of use, meaning that that effectively constrained generic libraries will not suffer from the usual problems of insane diagnostics. Libraries written using concepts will be far more readable and maintainable than the status quo. This talk will focus on generic programming, proposed language features, and their use in building real-world libraries.

Concepts Lite is a forthcoming ISO Technical Specification (TS) aimed at publication alongside C++14. Concepts Lite is implemented in a branch of GCC, which will be made available to the audience for experiments and experience.

The bell has tolled for rand()--Indi

By Adrien Hamelin | Feb 2, 2015 03:07 PM | Tags: experimental c++11 advanced

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In their recent meeting in Urbana, the C++ standard committee took the rare step of removing several outdated facilities from (what will probably become) C++17.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

By Adrien Hamelin | Feb 2, 2015 08:00 AM | Tags: experimental c++17

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

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

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.

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...
