2022 Annual C++ Developer Survey "Lite"

By Blog Staff | May 31, 2022 03:40 PM | Tags: None

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.

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

The Ranges Library in C++20: More Details

by Rainer Grimm

From the article:

Thanks to the ranges library, working with the Standard Template Library (STL) is much more comfortable and powerful. The algorithms of the ranges library are lazy, can work directly on the container, and can easily be composed. But there is more to it...

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>)...

C++20 Ranges Algorithms - 11 Modifying Operations

From the article:

In the previous article in the Ranges series, I covered some basics and non-modifying operations. Today it’s time for algorithms like transform, copy, generate, shuffle, and many more…. and there’s rotate as well

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

Flying to the future.

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...

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.
