A status update for the work done on OpenMP for Clang/LLVM and future directions presented at the 2014 LLVM Developers' Meeting. The slides are also available here.

OpenMP* Support in Clang/LLVM: Status Update and Future Directions

OpenMP is a well-known and widely used API for shared-memory parallelism. Support for OpenMP in Clang/LLVM compiler is currently under development. In this talk, we will present current status of OpenMP support, what is done and what remains to be done, technical details behind OpenMP implementation. Also, we will elaborate on accelerators and pragma-assisted SIMD vectorization, introduced in the latest 4.0 edition of the OpenMP standard.

A preview what is going into C++17 after the recent Standards Committee meeting. 

GoingNative 32: Sneak Preview of C++17

By Gabriel Ha

From the article: 

Join us with ISO Committee member (and Microsoft as well, of course =P) Gabriel Dos Reis, who graciously took the time to give us the inside scoop of some things that made it into C++17, as well as things that got taken out. All this is fresh off the press of the most recent C++ Standards Meeting...

Efficiency with Algorithms, Performance with Data Structures -- Chandler Carruth

By George Ryan | Dec 2, 2014 08:38 AM | Tags: performance c++14 c++11

At the recent CppCon 2014, Chandler Carruth gave a great talk on using Modern C++ for writing high-performance applications. 

Efficiency with Algorithms, Performance with Data Structures

by Chandler Carruth

From the video introduction:

C++ programmers throughout the industry have an insatiable desire for writing high performance code. Unfortunately, even with C++, this can be really challenging. Over the past twenty years processors, memory, software libraries, and even compilers have radically changed what makes C++ code fast. Even measuring the performance of your code can be a daunting task. This talk will dig into how modern processors work, what makes them fast, and how to exploit them effectively with modern C++ code.

CppCon videos now even more widely available via Channel 9

This just in on CppCon.org:

Video Availability Increased

As of today, CppCon 2014 session videos are available on Channel 9 at: http://channel9.msdn.com/Events/CPP/C-PP-Con-2014

The videos were originally made available and are still available on the CppCon YouTube channel at: https://www.youtube.com/CppCon

After posting the videos on YouTube, we received requests for additional availability from countries where YouTube is not available. We’ve worked with Channel 9 to be an additional hosting site. Channel 9 is available in countries where YouTube is not, so this helps us in our goal of supporting C++ developers all over the world.

Channel 9 also supports downloading the sessions in a number of formats, including audio only, for offline use.

The CppCon 2014 conference videos feature are over 100 sessions of C++ content from many of the world’s best C++ experts, all professionally recorded and edited by Bash Films. We are grateful to both YouTube and Channel 9 for hosting our content.

How Microsoft is taking on the cross-platform challenge with Office -- Mary Jo Foley

Modern C++, modern apps:

How Microsoft is taking on the cross-platform challenge with Office

by Mary Jo Foley

Summary: Microsoft's Office team has a new approach designed to allow it to share more of Office's code across not just Windows, but also Android, iOS and the Web.

Note: This is a 50-minute version of the same talk given at CppCon in two one-hour sessions. After presenting this at CppCon, Igor was invited to present the information also at Facebook's @Scale.

See also Dropbox's CppCon talk about how Dropbox uses a similar architecture, and moved to C++ to enable a single cross-platform source base after initially having written separate apps in Java for Android and Objective-C for iOS.

From the article:

Zaika talked about Microsoft's Office cross-platform architecture strategy at the recent Facebook @Scale conference. ... In his 50-minute session, Zaika detailed how Microsoft is building Office across Windows, Apple, Android and the Web by using C++. ...

The goal is to maintain a shared core of intellectual property — the guts of Office — all written in C++ and keep that shared core as large as possible. By doing this, risks of document corruption are reduced. On top of that core, there is a set of native UX application programming interfaces. ...

The goal of "write once, run anywhere" which technologies like Java, Flash and HTML5 were designed to try to solve by pushing the level of abstraction as low as possible or making application programming interfaces (APIs) very broad sounded good, Zaika said, but ended up creating impedance mismatch. Compatibility and interoperability problems, among others, arose. "Either you blew up, or the OS (operating system) blew up," Zaika said. ...

With a common C++ core, a thin native UX layer and evolving PALs, Microsoft is building its Office apps so they work on different OSes with fairly little tweaking required. Zaika cited PowerPoint as an example, noting that only four percent of its tens of millions of lines are unique to the WinRT/Universal version of Office (the touch-first Office release some of us have been calling "Gemini"). If the XAML code is excluded, the amount of shared code is 98.6 percent he said. The PowerPoint for Android code base includes 95 percent shared code, Zaika said.

At CppCon last month, InformIT recorded this video interview. It has now been posted: 

A Video Interview with Herb Sutter on C++ Standards

with Brian Overland

From the synopsis:

Herb Sutter ... talks with Brian Overland about how the standards committee evaluates proposals, the importance of being egoless, how to submit a proposal to the standards committee, why the committee decided to update the standard every three years, and the adoption of C++ in cross-platform mobile apps.

From the CppCon blog:

2014 Videos Online

We are announcing the CppCon Channel on YouTube with the first uploads of our video from CppCon 2014.

Our first videos feature our three keynote presentations from Bjarne Stroustrup, Mark Maimone, and Mike Acton; as well as our opening and closing plenary sessions from Scott Meyers and Herb Sutter. 

Over the next few weeks we’ll be uploading videos of most of the conference sessions including panels, lightning talks, and over one hundred sessions from the six tracks that made up the core of our conference program. The first two of our regular session uploads are from Michael Caisse and Thomas Rodgers.

We’d like to thank the speakers for allowing these sessions to be recorded and shared and Bash Films for the production of these videos.

A Conversation with Bjarne Stroustrup, Carl Hewitt, and Dave Ungar -- Charles Torre

An appetizer while the CppCon videos are being processed, we are pleased to link to this interview on Channel 9:

A Conversation with Bjarne Stroustrup, Carl Hewitt, and Dave Ungar

by Charles Torre

What happens when you put three titans of programming language design and computing in a room and turn a camera on to capture what takes place?

That's the thought experiment that led to this conversation with C++ language creator Bjarne Stroustrup, Self language creator Dave Ungar, and actor model creator Carl Hewitt. Thank goodness all three of them were present at Lang.NEXT 2014. Many topics are covered, as you can imagine. It's best that you find some quality time to watch, listen, and learn from some true masters. This is a long conversation and there is great programming history herein!

This is a rare (and very candid) gathering of some of the best minds in the programming world today.

Huge thanks to Bjarne, Carl, and Dave for spending over an hour to make conversation in real time. The topics naturally evolved out of the random and it was an honor to be in the room with such wonderful people who've had such a huge impact on programming.

Tune in. Enjoy.
