HPX V1.5 released -- STE||AR Group

By Hartmut Kaiser | Sep 2, 2020 09:33 AM | Tags: performance parallelism heterogeneous computing distributed computing concurrency c++20 c++17 c++14 c++11

The STE||AR Group has released V1.5 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.5 Released

The newest version of HPX (V1.5) is now available for download! This is a big release with many changes and improvements. We have added numerous new features, adapted a lot of facilities to improve C++20 conformance. We have also continued our work on modularizing and making HPX lighter, improved its usability, stability, and performance. Please see here for full 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++ Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 parallel 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++20 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.

 

Write cleaner, safer, modern C++ code with SonarQube

By ganncamp | Sep 1, 2020 07:15 AM | Tags: None

SonarSource will present a 30min webinar Wednesday, Sept 2 at 15:00 GMT to show how you can use SonarQube and SonarLint static analysis to write better C++. Even if you can't attend, sign up and we'll send you a link to the recording afterward.

Write cleaner, safer, modern C++ code with SonarQube

by SonarQube

From the announcement:

As a C++ Developer, you know that writing clean, secure, modern C++ code is important for you and your users. At SonarSource, we know that only developers can truly impact Code Quality and Security, so we put the power in your hands.

SonarQube makes C++ development easier with static code analysis that's powerful, fast, and accurate - right out of the box. Analysis is easy to integrate into your workflow and works with most common compilers, including many for embedded systems. Come see for yourself how you can make your C++ projects more reliable and secure.

Therefore, most likely, now each release will be followed by a special note so that users don't miss changes that may be useful to them. What's interesting is that from now on we won't just list everything that was added or improved. Rather, now on the contrary, the purpose is to highlight the most important features in the news to avoid having just a boring list of changes.

PVS-Studio 7.09

by Andrey Karpov

From the article:

New general analysis diagnostics:

  •     V1059. Macro name overrides a keyword/reserved name. This may lead to undefined behavior.
  •     V1060. Passing 'BSTR ' to the 'SysAllocString' function may lead to incorrect object creation.
  •     V1061. Extending 'std' or 'posix' namespace may result in undefined behavior.
  •     V1062. Class defines a custom new or delete operator. The opposite operator must also be defined.
  •     V1063. The modulo by 1 operation is meaningless. The result will always be zero.

SYCL is an open standard developed by the Khronos™ Group that enables developers to write code for heterogeneous systems using standard C++.

New Features in SYCL 2020

by Codeplay

About the blog:

The SYCL 2020 specification has been released for public review as a provisional specification and the group is looking for developers to provide their valuable feedback before the final version is published and ratified. In this blog engineers from Codeplay that are also contributors to the SYCL Working Group, the team that defines the standard within Khronos, talk about what they think will make developing with SYCL even better when using SYCL 2020.
