Parallelizing the C++ Standard Template Library

by Grant Mercer & Danial Bourgeois

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

As the era of frequency scaling comes to an end, multi-core parallelism has become an essential focal point in computational research. Mainstream languages, however, have not yet adapted to take full advantage of parallelism provided by the hardware. While new languages such as Rust and Swift are catching on and implementing multi-core algorithms in their libraries, C++ has only started to do so. A parallel Standard Library could bring with it many positive features that users can begin taking advantage of.

This talk will focus around two standards proposals, N4409 and N4406. N4409 outlines the details of a parallel Standard Library and features of these new parallel algorithms. The complementary N4406 outlines abstractions to take advantage of various mechanisms for parallel execution. We will cover the reasons why the new Standard Library would be beneficial to C++ users and our experience implementing these algorithms in HPX. The presentation will address what exactly the two proposals define, the challenges we faced, and the results we collected. In addition, we will discuss extensions made to these proposals and the C++11/14 standard in HPX to support these semantics in a distributed environment.

CppChat - Slashing on C++--Jon Kalb

The first video of CppChat is here:

CppChat - Slashing on C++

by Jon Kalb

From the description:

A live conversation about the latest in the C++ world. This week we'll be talking about Oulu, C++17, CppCon, and the latest conversations on C++.

We'll be featuring Bryce Adelstein Lelbach, Michael Caisse, and Jon Kalb. Bryce will be overflowing about his trip to Oulu, Jon will be overflowing about CppCon, and Michael will keep us on track.

This is our first time so it is likely to be very rough. But you'll join us for the content, not the polish.

Meeting C++ 2016: closing keynote & full schedule

With the announcement of the closing keynote the full schedule for Meeting C++ 2016 stands!

Closing keynote & full schedule of Meeting C++ 2016

by Jens Weller

From the article:

Since mid of June the program of the 5th Meeting C++ conference was taking shape. With the selection of the talks it was also clear in which tracks they go, so that the schedule it self was almost ready, except a last detail: the closing keynote.

The closing keynote will be held by Louis Dionne on "C++ metaprogramming: evolution and future directions".

Red Hat at the ISO C++ Standards Meeting (June 2016, Oulu): Library--JWAKELY

Red Hat at the ISO C++ Standards Meeting (June 2016, Oulu): Library

by JWAKELY

From the article:

The recent WG21 meeting in Oulu, Finland, was an especially busy one for the Library Working Group. Every day was spent working through the list of proposals intended for inclusion in C++17, and we also had three “evening” sessions that ran well past the evening (until nearly midnight, although the sun was still up to trick us into working late)...

Red Hat at the ISO C++ Standards Meeting (June 2016, Oulu): Core Language

by Jason Merrill

From the article:

It was quite a trek to get to Oulu, Finland for the June 2016 C++ Standards Committee meeting, but we were warmly received and the meeting went well once we arrived. We had very pleasant weather most of the week, and it was fun to experience the midnight sun, even though it played havoc with my sleep schedule.

Red Hat at the ISO C++ Standards Meeting (June 2016, Oulu): Parallelism and Concurrency--Torvald Rie

Red Hat at the ISO C++ Standards Meeting (June 2016, Oulu): Parallelism and Concurrency

by Torvald Riegel

From the article:

Several Red Hat engineers recently attended the JTC1/SC22/WG21 C++ Standards Committee meetings in Oulu, Finland.  This post focuses on the sessions of SG1 (the standards committee sub-group 1 – for concurrency and parallelism) as well as on coroutines-related sessions. Jason already gave an overview of the meeting in his post.

CppCon 2015 Large Scale C++ with Modules: What You Should Know--Gabriel Dos Reis

Large Scale C++ with Modules: What You Should Know

by Gabriel Dos Reis

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

“Modules” are a frequently requested and long-awaited feature by C++ programmers. In a nutshell, the idea is to have a direct language support for (a) expressing the boundaries and dependencies of a program component; (b) isolating source codes from macro vagaries; (c) scaling compile time, especially for large projects, given the ubiquity of “headers-only” template libraries; (d) spur innovation and deployment of semantics-aware developer tools.

This presentation will focus on three major points: (1) the design of the module proposal currently being considered by the C++ standards committee (design goals, properties, constraints); (2) implementations currently under way; and (3) early user experience and migration.

Modules directly address a problem (scalability) listed as one of the three major areas where C++17 is expected to significantly improve daily experience of the working C++ programmer. Naturally, this feature is also on the top ten list of C++17 functionalities Bjarne Stroustrup put forward in his “Thought on C++17.”

CppCon 2015 functional: What's New, And Proper Usage--Stephan T. Lavavej

functional: What's New, And Proper Usage

by Stephan T. Lavavej

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

functional gained lots of machinery in C++11, with further changes in C++14 and C++17. This talk will cover what's new in 11/14/17, focusing on how to use it properly. For example, you've probably used std::function, but do you know the criteria for activating the Small Functor Optimization? (It's not just being small!) We'll also look at bind(), mem_fn(), C++17's invoke(), and more.

Haskell Design Patterns for Genericity & Asynchronous Behavior

by Sherri Shulman

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

The paper explores some of Haskell's support for genericity through type classes, Functors, Monads, and Continuations and their impact on lanugages such as C++, Scala, and Rust. We explore these language features and consider alternatives that have been proposed to existing language features, including Object Algebras, GADTs, Open data types, open pattern matching, and extensions to Haskell's type system that impact the type inference algorithm and decidability. We use a number of case studies to demonstrate what proposed solutions look like in the target languages, considering how easy they are to use and how well the solutions integrate with existing linguistic features.
