by Vladislav Bogdanov

From the article:

We've begun work to expand the PVS-Studio's coverage of the MISRA C standard. With the release of 7.35, the first eight diagnostic rules have already been implemented, and more are on the way. The full list of implemented rules is provided below. We plan to cover at least 85% of MISRA C and support the latest version of MISRA C 2023.

PVS-Studio 7.34: support for Apple Silicon ARM64, CodeChecker

PVS-Studio 7.34: support for Apple Silicon ARM64, CodeChecker

by Aleksandra Uvarova

From the article:

New diagnostic rules. C, C++:

• V1116. Creating an exception object without an explanatory message may result in insufficient logging.
• V1117. The declared function type is cv-qualified. The behavior when using this type is undefined.
• V2022. Implicit type conversion from integer type to enum type.
• V5014. OWASP. Cryptographic function is deprecated. Its use can lead to security issues. Consider switching to an equivalent newer function.

HPX V1.10.0 released -- STE||AR Group

By Hartmut Kaiser | May 29, 2024 07:43 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 V1.10.0 of HPX -- A C++ Standard library for Concurrency and Parallelism.

HPX V1.10.0 Released

We have released HPX 1.10.0 — a major update to our C++ Standard Library for Concurrency and Parallelism. We have continued to modernize HPX to fully conform to the latest standardization efforts in the are of parallelism and concurrency. Our HPX documentation has seen a major overhaul for this release, please have a look here. We finished documenting the public local HPX API, we have added migration guides from widely used parallelization platforms to HPX (OpenMP, TBB, and MPI). Among other things, we have performed a lot of code cleanup and refactoring to improve the overall code quality and decrease compile times and to improve the consistency of our exposed APIs. The core implementation has seen many performance optimizations that impact every aspect of our applications.

If you have any questions, comments, or exploits to report you can reach us on IRC or Matrix (#ste||ar on libera.chat) or email us at hpx-users. We depend on your input!

You can download the release from our releases page or check out the v1.10.0 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, C++20, and C++23 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.
