Colony – A brief history of timing

by Matt Bentley

From the article:

Back in 2014 I began designing a game engine. Experienced programmers and curmudgeonly lecturers will tell you that if you make a game engine, you’ll never make a game – which is true, but sort of irrelevant. You will learn so much from making a game engine, you probably won’t care about the game by the end of it. The main reason I wanted to develop a game engine was that I was tired of seeing very basic 2D games with incredibly bad performance even on fast computers. If we got 15 frames-per-second on Intel 386 processors in the 1990s, why was it so hard for modern 2D games to achieve the same speed on exponentially-better hardware?

HPX V1.6.0 released -- STE||AR Group

By Hartmut Kaiser | Feb 18, 2021 07:18 AM | Tags: performance parallelism heterogeneous computing distributed computing concurrency c++20 c++17 c++14 c++11

The STE||AR Group has released V1.6.0 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.6.0 Released

The newest version of HPX (V1.6.0) is now available for download! This release continues the focus on C++20 conformance with multiple new algorithms adapted to be C++20 conformant and becoming customization point objects (CPOs). We have added experimental support for HIP, allowing existing CUDA features to now be compiled with hipcc and run on AMD GPUs as well. We have also continued improving the performance of the parallel executors, and added an experimental fork-join executor. The full list of improvements, fixes, and breaking 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++ 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.

 

Looking for C++ Employers for the online C++ Job fair on March 16th

Meeting C++ organizes the 2nd online C++ job fair on March 16th!

Looking for C++ Employers for March 16th

by Jens Weller

From the article:

Meeting C++ organizes the 2nd online C++ Job fair on March 16th!

The first online job fair in October 2020 was a big success, and now with the world coming back from the pandemic, I'd like to continue organizing these events online. This time the event will take place in wonder.me, a platform where users can freely roam around on a virtual map and engage in conversations by joining a circle. Join the Meeting C++ online User Group for further updates on the event.

The virtual job fair where you can attend and talk to different employers or job searchers is planned for March 16th. For Tuesday afternoon from 15-18:00 (CET) you'll be able to join the event and talk to employers and other job searchers. Each employer that registers will have its own named area. Employers need to sign up until March 10th.

ACCU’s Overload journal of February 2021 is out. It contains the following C++ related articles.

Overload 161 is now available

From the journal:

In. Sub. Ordinate.
By Frances Buontempo
Mindless rebellion is mindless. Frances Buontempo encourages mindful consideration of when to refuse.

A Case Against Blind Use of C++ Parallel Algorithms
By Lucian Radu Teodorescu
C++17 introduced parallel algorithms. Lucian Radu Teodorescu reminds us we need to think when we use them.

C++ – an Invisible Foundation of Everything
By Bjarne Stroustrup
What is C++ and why do people still use it? Bjarne Stroustrup provides a short note answering these questions.

Test Precisely and Concretely
By Kevlin Henney
Tests can hit complete coverage but fail to communicate. Kevlin Henney reminds us that assertions should be necessary, sufficient, and comprehensible.

Afterwood
By Chris Oldwood
Think you’ve learnt it all? Chris Oldwood reminds us that unlearning then becomes our next problem.

Another book.

Book “Beginning C++20”

by Marc Gregoire

From the article:

My friend Peter Van Weert finished a new edition of “Beginning C++20” for which I was technical editor. It’s a great book to learn C++20 for programmers new to C++ and those who may be looking for a refresh primer on C++ in general...

GotW #99 Solution: Postconditions -- Herb Sutter

Solution just posted:

GotW #99 Solution: Postconditions

by Herb Sutter

From the article:

Postconditions are directly related to assertions (see GotW #97)... but how, exactly? And since we can already write postconditions using assertions, why would having language support benefit us more for writing postconditions more than for writing (ordinary) assertions?

How std::any Works

by Jonathan Boccara

From the article:

In the previous post we’ve seen a very nice technique to use value semantics with inheritance and virtual methods, which was made possible by std::any.

Given its usefulness, it would be interesting to better understand std::any. Indeed, std::any is sometimes said to be “the modern void*“. But it does much more than a void*...
