San Diego Committee Meeting: A Trip Report

by Corentin Jabot

From the article:

As I left Rapperswil earlier this year, I said very firmly that I would not go to the San Diego Meeting.

Crossing an ocean to work on C++ 12 hours a day for a week is indeed madness.

And so naturally, I found myself in a San Diego hotel straight from the 60s, to do some C++ for a week. With the exception of the author of this blog, all people there are incredibly smart and energetic, and so a lot of great work was done...

Trip Report: Freestanding in San Diego--Ben Craig

Trip Report: Freestanding in San Diego

by Ben Craig

From the article:

All three are dealing with "freestanding". I've been working for the last year or so trying to redefine freestanding in a way that would be useful to more people. I have personal experience using C++ in various operating system kernels / drivers, and a bit of experience working on micro controllers and digital signal processors, so that's where my papers focused. At the CppCon 2018 SG14 meeting, some GPU companies have said that my definitions are useful for their architectures (with some tweaks), and I've heard from several other people that my definitions are even useful in some environments where performance and determinism are key, even when there is an OS. I'm still trying to figure out if and how to incorporate all these groups into one thing that could get standardized.

I pitched "Freestanding Proposal" at my first WG21 meeting was November of 2017 in Albuquerque. I was an unknown then. San Diego was my third WG21 meeting. All the papers and interviews and trip reports have now made it where people were asking me about freestanding quite frequently. There were a few times I got stopped while walking around by someone I had never talked to before, and they knew who I was, and asked about freestanding. I found this very flattering. I'm thrilled (and terrified) that my work is getting such visibility...

The Amazing Performance of C++17 Parallel Algorithms, is it Possible?--Bartlomiej Filipek

The Amazing Performance of C++17 Parallel Algorithms, is it Possible?

by Bartlomiej Filipek

From the article:

With the addition of Parallel Algorithms in C++17, you can now easily update your “computing” code to benefit from parallel execution. In the article, I’d like to examine one STL algorithm which naturally exposes the idea of independent computing. If your machine has 10-core CPU, can you always expect to get 10x speed up? Maybe more? Maybe less? Let’s play with this topic.

Sourcetrail 2018.4 released

Sourcetrail is a cross-platform visual source explorer based on LLVM/Clang LibTooling

Sourcetrail 2018.4 released

by Eberhard Gräther

From the article:

Sourcetrail 2018.4 features big improvements on indexing performance and reduced memory consumption. The new tab bar in the application window allows for opening multiple symbols simultaneously, just like in a web browser. Also, new type-use edges were added to the graph visual, to make exploration of types easier when templates are involved.

A beginner's look at smart pointers in modern C++

New (!) ways of memory management.

A beginner's look at smart pointers in modern C++

by Triangles @ Internal Pointers

From the article:

Pointers in C and C++ languages are wild beasts. They are extremely powerful, yet so dangerous: a little oversight may wreak havoc on your whole app. Smart pointers were born to fix such annoyances. They provide automatic memory management: when a smart pointer is no longer in use, that is when it goes out of scope, the memory it points to is deallocated automatically.

 

Trip report: Fall ISO C++ standards meeting (San Diego) -- Herb Sutter

Fresh from last week's standards meeting:

Trip report: Fall ISO C++ standards meeting (San Diego)

by Herb Sutter

From the article:

On Saturday November 10, the ISO C++ committee completed its fall meeting in San Diego, California, USA, hosted with thanks by Qualcomm. This was the biggest ISO C++ meeting in our 29-year history, with some 180 people at the meeting, representing 12 nations...

Because this is one of the last meetings for adding features to C++20, we gave priority to proposals that might make C++20, and we adopted a number of them for C++20...

HPX V1.2 released -- STE||AR Group

By Hartmut Kaiser | Nov 13, 2018 08:22 AM | Tags: performance parallelism heterogeneous computing distributed computing c++17 c++14 c++11

The STE||AR Group has released V1.2 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.2 Released

The newest version of HPX (V1.2) is now available for download! Please see here for the release notes. This release is the first in our more frequent release schedule. We are aiming to produce one release every six months in an effort to get new features and stable releases out to users more quickly.

    HPX exposes an API fully conforming to the parts of the C++11/C++14/C++17 standards that are related to parallelism and concurrency, extended and applied to distributed and heterogeneous computing, and aligned with the ongoing standardization discussions.

    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 which tends to improve the parallel efficiency of our applications and helps reducing complexities usually associated with parellism and concurrency.

 

2018 San Diego ISO C++ Committee Trip Report

By Adrien Hamelin | Nov 12, 2018 01:29 PM | Tags: experimental

The report is here!

2018 San Diego ISO C++ Committee Trip Report

From the article:

The ISO C++ Committee met in San Diego, California ���� last week to continue work on the next International Standard (IS), C++20. This meeting was the last meeting to consider new proposals for C++20, but existing proposals like modules (on track) and coroutines (questions remain) that are in flight but not merged can still make C++20. We’ll make our final decisions about major language features at the next meeting.
