Have you registered for CppCon 2017 in September? Don’t delay – Registration is open now.
While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:
Improving Performance Through Compiler Switches...
by Tim Haines
Summary of the talk:
Much attention has been given to what modern optimizing compilers can do with your code, but little is ever said as to how to make the compiler invoke these optimizations. Of course, the answer is compiler switches! But which ones are needed to generate the best code? How many switches does it take to get the best performance? How do different compilers compare when using the same set of switches? I explore all of these questions and more to shed light on the interplay between C++ compilers and modern hardware drawing on my work in high performance scientific computing.
Enabling modern optimizing compilers to exploit current-generation processor features is critical to success in this field. Yet, modernizing aging codebases to utilize these processor features is a daunting task that often results in non-portable code. Rather than relying on hand-tuned optimizations, I explore the ability of today's compilers to breathe new life into old code. In particular, I examine how industry-standard compilers like those from gcc, clang, and Intel perform when compiling operations common to scientific computing without any modifications to the source code. Specifically, I look at streaming data manipulations, reduction operations, compute-intensive loops, and selective array operations. By comparing the quality of the code generated and time to solution from these compilers with various optimization settings for several different C++ implementations, I am able to quantify the utility of each compiler switch in handling varying degrees of abstractions in C++ code. Finally, I measure the effects of these compiler settings on the up-and-coming industrial benchmark High Performance Conjugate Gradient that focuses more on the effects of the memory subsystem than current benchmarks like the traditional High Performance LinPACK suite.

A post about an application of the new Metaclasses proposal.
Metaclasses for embedded domain specific languages
by Simon Brand
From the article:
Metaclasses are a proposed feature to C++ which will allow the creation of abstractions over classes and the extension of the language’s type definition system. Templates are a powerful host for other languages, and metaclasses only make them more so.

Episode 108 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Christopher Di Bella to talk about his experience teaching C++ and his proposed changes to Concepts.
CppCast Episode 108: Teaching Concepts with Christopher Di Bella
by Rob Irving and Jason Turner
About the interviewee:
Christopher Di Bella will soon be a Runtime Technology Engineer at Codeplay, and was previously university tutor (teaching assistant) for the course 'Advanced C++ Programming', at the University of New South Wales, Australia. He is an avid C++ programmer, and also enjoys film, board games, and snowboarding in his spare time.

Complete set up of a project:
Modern C++ CI
by Juan Medina
From the article:
Modern C++ is great, some people are even calling it a new language, but is not only the language what is evolving the tool-chain is getter better, so doing continuous integration for cross platform projects is simple and effective.
I decide to do a simple project using some of the C++14 features and following the C++ Core Guidelines whenever its possible. The result is available in this repository.

What’s the point of coroutines?
A more realistic coroutine
by Kirit Sælensminde
From the article:
Having gotten something working, we still have a small problem. We have a coroutine that we can start, and we can choose when to suspend it, but we can't yet resume it.
The coroutines TS describes a class
std::experimental::coroutine_handlewhich is our interface to the coroutine itself. It's a template which is supposed to be told the promise_type we're using...

Meeting C++ exists now for 5 years, lets celebrate on the blog:
5 years of Meeting C++
by Jens Weller
From the article:
Just a little bit more then 5 years ago, Meeting C++ went public. Since then, it has been a wild ride and huge success. Today, Meeting C++ reaches over 50k in social media, the conference it self has grown from 150 to 600 in its 5 editions...

A reminder from the CppCon blog:
Early bird registration ends this weekend
by Jon Kalb
From the post:
No matter when you register for CppCon 2017, you be able to meet with:
- over a thousand other professional C++ engineers, including book, blog, and library authors, standards committee members, compiler and other tool implementers, and teachers and trainers;
- scores of the best presenters in the industry; and
- exhibitors from all over the world
and attend:
- five days of six or seven tracks of peer-reviewed presentations,
- daily plenary talks from recognized industry leaders,
- multiple lightning talk sessions,
- expert panels and special sessions,
- poster presentations, and
- social events.
But if you do it this week, you save more than enough money to join us at the Boeing Future of Flight Field Trip.
To help you decide, here is this year’s promo video:
