Heterogeneous Lookup in Ordered Containers, C++14 Feature

by Bartlomiej Filipek

From the article: 

If you have a map of strings, like std::map<std::string, int> m; and you want to find some element by m.find("abc"). Do you have to pay the price and construct a std::string object? Can you optimize it?

Let’s have a look at one feature enabled in C++14 that might help optimize such container access...

HPX V1.3 released -- STE||AR Group

The STE||AR Group has released V1.3 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.3 Released

The newest version of HPX (V1.3) is now available for download! This release focuses on performance and stability improvements. Please see here for the 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 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 parellism and concurrency.

 

Submit your talk to Meeting C++ 2019!

The call for submissions is open for Meeting C++ 2019!

New speakers are welcome to submit as there is a dedicated track for this, start speaking at Meeting C++!

Submit your talk to Meeting C++ 2019!

by Jens Weller

From the article:

When Meeting C++ 2019 was announced in the begin of April, there was already a hint that you could submit your talks. And so far a few have done so. Now its time for an official news entry. Submit your talk to Meeting C++ 2019! This year its the 8th edition of Meeting C++!

Speaking at Meeting C++ is a fun experience, you get to attend the speakers dinner, attend the full conference for free and enjoy the luxurious Hotelrooms the Andels offers from Wednesday to Saturday! You can look at last years schedule to get a feel for what your competition might talk about, but have in mind that you don't see the talks that were not submitted! If you want to talk about a C++ topic that wasn't covered yet, or have a unique idea for your talk, please submit! Speakers don't need to buy a ticket and the conference has a contingent of rooms available for speakers & staff.

Game performance and compilation time improvements in Visual Studio 2019--Gratian Lup

Game performance and compilation time improvements in Visual Studio 2019

by Gratian Lup

From the article:

The C++ compiler in Visual Studio 2019 includes several new optimizations and improvements geared towards increasing the performance of games and making game developers more productive by reducing the compilation time of large projects. Although the focus of this blog post is on the game industry, these improvements apply to most C++ applications and C++ developers...

A gentle introduction to jump threading optimizations

by Aldy Hernandez

From the article:

As part of the GCC developers‘ on-demand range work for GCC 10, I’ve been playing with improving the backward jump threader so it can thread paths that are range-dependent. This, in turn, had me looking at the jump threader, which is a part of the compiler I’ve been carefully avoiding for years. If, like me, you’re curious about compiler optimizations, but are jump-threading-agnostic, perhaps you’ll be interested in this short introduction...

HPX V1.2.1 released -- STE||AR Group

The STE||AR Group has released V1.2.1 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.2.1 Released

The newest version of HPX (V1.2.1) is now available for download! Please see here for the release notes. This release is a pure bug fix release that addresses a couple of compatibility problems (in particular with Boost V1.69). We have also included some important improvements that were merged since the previous release.
