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.

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.

CppCon 2015 Integrating generators EDSL's for Spirit X3 (WIP)--Feliple Magno de Almeida

Integrating generators EDSL's for Spirit X3 (WIP)

by Feliple Magno de Almeida

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Based on the presentation I made on C++Now 2015 for Developing EDSL's for Boost.Spirit V2, present the development of generators for Boost.Spirit X3 (next version of boost spirit) and how that can be used for higher abstraction EDSL's while, through template metaprogramming, create parsers and generators automatically from the same grammar, using CORBA format as an example, while dealing with endianness, alignment and asymmetric grammars. This work is based on the library mORBid (https://github.com/expertisesolutions...) and (https://github.com/expertisesolutions...).

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.”

CppCast Episode 63: IncludeOS with Alfred Bratterud

Episode 63 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Alfred Bratterud, CEO of IncludeOS to discuss Microservice applications with the IncludeOS platform.

CppCast Episode 63: IncludeOS with Alfred Bratterud

by Rob Irving and Jason Turner

About the interviewee:

Alfred has been doing research towards IncludeOS since 2013, and got a PhD scholarship based on the early work in 2014. The IEEE CloudCom paper introducing the IncludeOS prototype was published in 2015 and he spun out a startup around IncludeOS in 2016, in collaboration with Oslo and Akershus university college (the largest institution for engineering education in Norway). He's currently focusing 100% on developing IncludeOS from research experiment to a production ready platform for cloud services.

Alfred holds BSc and MSc in computer science, with focus on logic and computability, from the university of Oslo. He has 10+ years of industrial programming experience, mostly in web services. He's been working at Oslo university college since 2011, teaching various subjects ranging from operating systems, sysadmin and firewalls to web development. He started learning C++ when he took over a C++ course at the college in 2011. A very good year to start C++.

Organizational Leadership with Modern C++

by Kevin Kostrzewa & Johm Wyman

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

With the "C++ Renaissance" it is imperative that the technical leadership prove their mettle to lead a large organization into adopting modern practices and idioms.

In this talk, John and Kevin will discuss various techniques that they have employed to help drive their large development organization (~ 75 software engineers) towards a culture of modernization - some techniques that have worked well, and some that have not.

This will not be a discussion on specifics and nuances of the language. This is more a "fuzzy" discussion on what it means to be both at the forefront of the language and a leader / champion for your peers.
