Day-before reminder: Survey closes tomorrow. If you haven't already, please take 10 minutes to help inform the committee and community.

Original announcement last week:

The Standard C++ Foundation's annual global C++ developer survey is now open. As the name suggests, it's a one-pager:

2022 Annual C++ Developer Survey "Lite"

Please take 10 minutes or so to participate! A summary of the results, including aggregated highlights of common answers in the write-in responses, will be posted publicly here on isocpp.org and shared with the C++ standardization committee to help inform C++ evolution.

The survey closes in one week tomorrow.

Thank you for participating and helping to inform our committee and community.

Check Types with Concepts--Rainer Grimm

The series continue.

Check Types with Concepts

by Rainer Grimm

From the article:

Concepts are a powerful and elegant tool to check at compile time if a type fulfills. Thanks to static_assert, you can use concepts as a standalone feature: static_assert(Concept<T>)...

How can I synthesize a C++20 three-way comparison from two-way comparisons?--Raymond Chen

How can I synthesize a C++20 three-way comparison from two-way comparisons?

by Raymond Chen

From the article:

The C++20 three-way comparison operator <=> (commonly nicknamed the spaceship operator due to its appearance) compares two items and describes the result. It’s called the three-way comparison because there are five possible results: less, equal, equivalent, greater, and unordered.

Yeah, the name is kind of weird...

Meeting C++ organized an event centered around sharing material on creating better talks and presentations for C++:

Technical Speaking about C++

by Jens Weller

About the article:

This event will focus on the process of creating technical talks for the C++ community. Various speakers will share their views on how to submit, prepare and give talks to the C++ community in the form of lightning talks.

 

HPX V1.8.0 released -- STE||AR Group

By Hartmut Kaiser | May 25, 2022 07:59 AM | Tags: performance parallelism heterogeneous computing distributed computing concurrency c++23 c++20 c++17 c++14 c++11

The STE||AR Group has released V1.8.0 of HPX -- A C++ Standard library for Concurrency and Parallelism.

HPX V1.8.0 Released

We have released HPX 1.8.0 -- a major update to our C++ Standard Library for Concurrency and Parallelism. The HPX parallel algorithms now have been fully adapted to C++20, all existing facilities have been adjusted to conform to this version of the Standard as well. We now can proudly announce full conformance to the C++20 concurrency and parallelism facilities. HPX supports all of the algorithms as specified by C++20. On top of that we support parallel versions of all range-based algorithms and have added support for explicit vectorization to more of our algorithms (using std::experimental::simd). Much work has been done towards implementing P2300 (std::execution) and the underlying senders/receivers facilities. Last but not least, we have finished the refactoring of the whole library into a rather large set of non-cyclically depending components. Finally, the new release comes with a brand new documentation interface!

You can download the release from our releases page or check out the 1.8.0 tag using git. A full list of changes can be found in the release notes.

HPX is a general-purpose parallel C++ runtime system for applications of any scale. It implements all of the related facilities as defined by the C++20 Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 and C++20 parallel algorithms, including a full set of parallel range-based algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the features related parallelism and concurrency as specified by the upcoming C++23 Standard, the C++ Concurrency TS, Parallelism TS V2, data-parallel algorithms, executors, and many more. It also extends the existing C++ Standard APIs to the distributed case (e.g., compute clusters) and for heterogeneous systems (e.g., GPUs).

HPX seamlessly enables a new Asynchronous C++ Standard Programming Model that tends to improve the parallel efficiency of our applications and helps reducing complexities usually associated with parallelism and concurrency.
