concurrency : Standard C++

HPX now exposes an API fully conforming to the concurrency related parts of the C++11 and C++14 standards, extended and applied to distributed computing.

From the announcement:

We completed the refactoring of hpx::future to be properly C++11 standards conforming.
We overhauled our build system to support newer CMake features to make it more robust and more portable.
We implemented a large part of the parallel algorithms and other parallel facilities proposed by C++ Technical Specifications N4104, N4088, and N4107.
We added many examples such as the 1D Stencil and the Matrix Transpose series.
We significantly improved the performance of the library and the existing documentation

I've started last year a video interview in Aspen - while at C++Now - with Michael Wong. This year I had the chance to finish the interview and I am now finally able to release it. Michael is a member of the C++ Committee for many years, he leads the Canadian delegation and also speaks for IBM at the C++ committee.

Lightweight HTTP Server in less than 40 Lines on libevent and C++11 -- NYM

Fresh on Kukuruku:

Lightweight HTTP Server in less than 40 Lines on libevent and C++11

by NYM

From the article:

Looking through programming articles sometimes I see posts about creating your own HTTP server. I am most interested in C++ so I often read blogs about it. After looking them through you could easily write you own web server “on sockets” using boost.asio or something else. I also examined libevent and libev. Each of them has its advantages. Libevent is of great interest to me for developing a small HTTP server. Considering some innovations in C++11 the code becomes much more space-efficient and allows for the creation of a basic HTTP server in less than 40 lines.

Async-Await in C++ -- Paolo Severini

By Marco Arena | Apr 28, 2014 08:52 AM | Tags: intermediate experimental concurrency

Paris, April 2014: Paolo Severini explores the Async-Await pattern and the related proposal for C++17, showing also an example by using Visual Studio 2013 November CTP.

Async-Await in C++

by Paolo Severini

From the article:

... what about native [C++] programming? Is there anything like async/await that we can use with our futures? We can find the answer in N3858, another proposal made by Gustafsson et al. for C++17.

This time the changes proposed are to the language itself and not just to the library. The idea is to introduce the equivalent of C# async methods in the form of resumable functions. They can be thought as the basis to add to C++ the support for real co-routines, and are not strictly related to the <future> library, even though they have being defined especially to improve the usability of futures and promises...

HPX version 0.9.8 released -- STE||AR Group

By Hartmut Kaiser | Mar 24, 2014 02:57 PM | Tags: performance parallelism distributed computing concurrency c++14 c++11

The STE||AR Group has released V0.9.8 of HPX -- A general purpose parallel C++ runtime system for applications of any scale.

HPX V0.9.8 Released

The newest version of HPX (V0.9.8) is now available for download! Please see here for the release notes.

HPX now exposes an API fully conforming to the concurrency related parts of the C++11 and the draft C++14 standards, extended and applied to distributed computing.

From the announcement:

A large part of the code base of HPX has been refactored and partially re-implemented: the threading and networking subsystems have been improved in performance, modularity, and robustness, the API was improved for closer conformance to the concurrency related parts of the C++11 and C++14 draft standards and the upcomming Concurrency TS.
We added new API functionality like hpx::migrate and hpx::copy_component which are the basic building blocks necessary for implementing higher level abstractions for system-wide load balancing, runtime-adaptive resource management, and object-oriented check-pointing and state-management.
We improved the distributed reference counting scheme used by HPX which helps managing distributed objects and memory.

CppCon 2014 Registration Open: September 7-12, Bellevue, WA, USA

By Blog Staff | Mar 18, 2014 04:00 AM | Tags: performance parallelism intermediate experimental efficiency cppcon concurrency c++14 c++11 boost basics advanced

The Standard C++ Foundation is very pleased to announce the first annual CppCon.

Registration is now open for CppCon 2014 to be held September 7–12, 2014 at the Meydenbauer Center in Bellevue, Washington, USA. The conference will start with the keynote by Bjarne Stroustrup titled "Make Simple Tasks Simple!"

CppCon is the annual, week-long face-to-face gathering for all C++ users. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in the beautiful Seattle neighborhood and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.

What you can expect at CppCon:

Invited talks and panels: The CppCon keynote by Bjarne Stroustrup will start off a week full of insight from some of the world’s leading experts in C++. Still have questions? Ask them at one of CppCon’s panels featuring those at the cutting edge of the language.

Presentations by the C++ community: What do embedded systems, game development, high frequency trading, and particle accelerators have in common? C++, of course! Expect talks from a broad range of domains focused on practical C++ techniques, libraries, and tools.

Lightning talks: Get informed at a fast pace during special sessions of short, less formal talks. Never presented at a conference before? This is your chance to share your thoughts on a C++-related topic in an informal setting.

Evening events and “unconference” time: Relax, socialize, or start an impromptu coding session.

CppCon’s goal is to encourage the best use of C++. The conference is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to support the C++ software developer community and promote the understanding and use of modern, standard C++ on all compilers and platforms.

Compiler support for C++11 and C++14

By Meeting C++ | Mar 7, 2014 06:57 AM | Tags: standardization intermediate experimental concurrency c++14 c++11 advanced

C++11 support is still an interesting topic, even that GCC and Clang now fully support it. Also the upcoming C++14 standard is already getting implemented by a lot of compilers. There are two very interesting publications about this topic in recent weeks, first, on italiancpp.org there is a PDF on C++11 and C++14 feature support for Visual C++, Intel, Clang and GCC. Also Just a few days ago, a interesting blogpost about this topic was published on C++Rocks, focussing on compiler and library support:

C++11/14 compiler and library shootout

by C++ Rocks

From the Article:

It’s been almost a year since my last comparison of C++11 support across different compilers, so I decided to take a break from working on my book about C++11/14 features in VS2013, and see how things have changed.

Thoughts on Monads and Futures in C++

C++17: I See a Monad in Your Future!

by Bartosz Milewski

From the Article:

If you thought you were safe from functional programming in your cozy C++ niche, think again! First the lambdas and function objects and now the monad camouflaged as std::future. But do not despair, it’s all just patterns. You won’t find them in the Gang of Four book, but once you see them, they will become obvious.

C++ Papers for Issaquah -- Concurrency

By Meeting C++ | Jan 29, 2014 07:47 AM | Tags: standardization performance intermediate experimental concurrency c++14 advanced

So I just started to read through the papers for the next C++ committee meeting in Issaquah in February, first part is about Concurrency:

C++ Papers for Issaquah -- Concurrency

by Jens Weller

From the article:

In february the C++ committee is going to meet for a week in Issaquah, it could be the final Meeting for C++14, the papers in this series will reflect both, C++14 and the standard that will come after it. Currently mostly known as C++1y. A lot of papers that are not part of C++14 will be formed into technical specifications, which some will then become C++1y later. Like the last series, I will again focus on the working groups, and post the papers sorted by the name of the working group, starting with concurrency.
