The case for Auto Non-Static Data Member Initializers—Corentin Jabot

The case for Auto Non-Static Data Member Initializers

By Corentin Jabot

 

From the article:

In this article, we talk about Auto Non-Static Data Member Initializers in C++. All code snippet can be tested on Compiler Explorer thanks to Matt Godbolt.

In fact, the main motivation for this article is to put this feature in the hand of people to prove that it works and that it would be a great addition to the standard.

Codeplay Announces World’s First Fully-Conformant SYCL 1.2.1 Solution

SYCL is an open standard developed by the Khronos™ Group that enables developers to write code for heterogeneous systems using standard C++.  Developers are looking at how they can accelerate their applications without having to write optimized processor specific code. SYCL is the industry standard for C++ acceleration, giving developers a platform to write high-performance code in standard C++, unlocking the performance of accelerators and specialized processors from companies such as AMD™, Intel™, Renesas™ and Arm®.

Codeplay Announces World's First Fully-Conformant SYCL 1.2.1 Solution

by Codeplay

About the release:

Codeplay's ComputeCpp 1.0 enables SYCL and provides C++ developers with huge benefits:
    High Performance Computing: Supercomputers are playing an important role in computationally intensive tasks in the fields of science, finance, and many others to provide complex calculations and simulations. SYCL offers a standard way for HPC developers to write portable, efficient, accelerated code using standard C++ that can be deployed to GPUs, FPGAs and other accelerators
    Computer Vision: Complex image processing operations can be accelerated using parallel computing. ComputeCpp and SYCL provide high-level programmability for custom vision processors, enabling additional custom features on top of existing optimized hardware functions
    Artificial Intelligence: Linear algebra is increasingly being used in artificial intelligence applications and benefits from parallel architectures. The Eigen linear algebra library, SYCLBLAS and TensorFlow frameworks can be accelerated using ComputeCpp for a wide variety of heterogeneous hardware

Results summary: C++ Foundation Developer Survey “Lite”, 2018-08: C++ and Cloud

Over the past week, we ran our second global C++ developer survey, this time focusing on C++ use in cloud-related workloads.

Thank you to everyone who responded. As promised, here is a public summary of the results:

CppDevSurvey-2018-08-cloud-summary.pdf

This summary has now been forwarded to the C++ standards committee, along with the full text of your write-in answers. Your feedback will be very helpful, and thank you again for your participation!

C++ Foundation Developer Survey “Lite”, 2018-08: C++ and Cloud

cpp_logo.pngThank you to the over 3,000 people who participated six months ago in the Standard C++ Foundation's first-ever global C++ developer survey. Based on its success, we have decided to run these surveys about twice a year to learn about C++ usage generally across industries or in specific current domains.

This time, we focus on the domain of cloud-related software. As the name suggests, it's a one-pager:

C++ Developer Survey "Lite", 2018-08: C++ and Cloud

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 will be open for one week.

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

Announcing “trivially relocatable”

by Arthur O’Dwyer

From the article:

Frequent users of Compiler Explorer, a.k.a. godbolt.org, may have noticed that a few days ago a new compiler appeared in its dropdown menu. “x86-64 clang (experimental P1144)” is a branch of Clang which I have patched to support the concept of “trivially relocatable types,” as described in my C++Now 2018 talk and as proposed for standardization in my upcoming paper P1144 “Object relocation in terms of move plus destroy” (coauthored with Mingxin Wang)...
