Fwd: Forthcoming Boost.Fiber review
by Nat Goodspeed 18 Dec '13

18 Dec '13

Hi all, The review of Boost.Fiber by Oliver Kowalke is scheduled from Monday, January 6th to January 12th. ----------------------------------------------------- About the library: Boost.Fiber provides a framework for micro-/userland-threads (fibers) scheduled cooperatively. The API contains classes and functions to manage and synchronize fibers similar to Boost.Thread. Each fiber has its own stack. A fiber can save the current execution state, including all registers and CPU flags, the instruction pointer, and the stack pointer and later restore this state. The idea is to have multiple execution paths running on a single thread using a sort of cooperative scheduling (versus threads, which are preemptively scheduled). The running fiber decides explicitly when it should yield to allow another fiber to run (context switching). Boost.Fiberinternally uses coroutines from Boost.Coroutine <http://ok73.funpic.de/boost/libs/coroutine/index.html>; the classes in this library manage, schedule and, when needed, synchronize those coroutines. A context switch between threads usually costs thousands of CPU cycles on x86, compared to a fiber switch with a few hundred cycles. A fiber can only run on a single thread at any point in time. docs: http://ok73.funpic.de/boost/libs/fiber/doc/html/index.html<http://ok73.ok.funpic.de/boost/libs/coroutine/doc/html/> git: https://github.com/olk/boost-fiber src: http://ok73.ok.funpic.de/boost.fiber.zip<http://ok73.ok.funpic.de/boost.coroutine.zip> --------------------------------------------------- Naturally, you need not wait until the review formally opens to start reviewing the Fiber library. Please always state in your review whether you think the library should be accepted as a Boost library! Additionally please consider giving feedback on the following general topics: - What is your evaluation of the design? - What is your evaluation of the implementation? - What is your evaluation of the documentation? - What is your evaluation of the potential usefulness of the library? - Did you try to use the library? With what compiler? Did you have any problems? - How much effort did you put into your evaluation? A glance? A quick reading? In-depth study? - Are you knowledgeable about the problem domain?

C++Now 2014: Call for Submissions, Updated deadlines
by Hartmut Kaiser 09 Dec '13

09 Dec '13

Updated submission dates! Please see below! ============================================== C++ Now Conference 2014 Aspen CO, USA, May 12-17, 2014, www.cppnow.org ============================================== For the full announcement online, please see here: http://cppnow.org/2013/10/21/2014-call-for-submissions/ Call for Submissions -------------------- We invite you to submit session proposals to the 3rd annual C++Now Conference (Aspen CO, USA, May 12-17, 2014). Building upon the resounding success of C++Now 2013 and five years of BoostCon, C++Now 2014 will present leading speakers from the whole C++ community. The C++Now Conference is dedicated to discussion and education about C++, an open and free language and standard. Our Conference will focus on discussion and education about open source software usage and developments in the C++ developer and user community. To reflect the breadth of the C++ and Boost communities, the conference includes sessions aimed at three constituencies: C++ and Boost end-users, hard-core Boost library and tool developers, and researchers pushing the boundaries of computation. The program fosters interaction and engagement within and across those groups, with an emphasis on hands-on, participatory sessions. As a multi-paradigm language, C++ is a melting pot where the most compelling ideas from other programming communities are blended in powerful ways. Historically, some of the most popular sessions at C++Now have highlighted these concepts, from DSLs to functional programming to transactional memory and more. Bring your C#, Python, Ruby or Haskell influences to bear in an environment that will broaden their exposure. At C++Now 2014 we would like to focus on the now established C++11 standard and the new, upcoming C++14 and how those standards are and will shape C++'s future. However, by no means is this intended to restrict the topics of proposals we hope to see. Any other topic related to C++ as outlined below is perfectly fine for submission. Important dates --------------- New proposal submissions due: December 22th, 2013. Proposals decisions sent (tentative program available): February 15th, 2014. Fully scheduled program available: February 28th, 2014. Best Presentation Awards ------------------------ We know how much effort it takes to prepare talks for our conference. For this reason we will award the best The awards will be given based on the audience's voting. Each award will include the author's name listed on the cover of the C++Now website for that year and a plaque containing all the C++Now conference information. Session topics -------------- Topics of interest include, but are not restricted to, the following: * C++11/14 and how it changes life for users and library writers * General tutorial sessions on C++11/14, the C++11/14 Standards library, and one or more Boost libraries * Parallelism in the new C++11/14 standard * Parallel, distributed and GPGPU topics relating to C++ * In-depth sessions on using specific Boost libraries * Case studies on using Boost * Experts panels * Advanced sessions on implementation techniques used within Boost libraries * Development workshops to extend or enhance existing Boost libraries * Workshops on design process * Infrastructure workshops such as Build tools, Website, Testing * Concepts and Generic Programming * Hardware and infrastructure presentations focused on how libraries can make better use of the technology * Software development tools and their application to C++ and or Boost * Other topics likely to be of great interest to C++ users and developers Interactive and collaborative sessions are encouraged, as this is the style of learning and participation that has proven most successful at such events. Sessions can be tutorial based, with an emphasis on interaction and participant involvement, or workshop based, whether hands-on programming or paper-based, discussion-driven collaborative work. Session formats --------------- Presentations Presentations focus on a practitioner's ideas and experience with anything relevant to C++11 or C++14, Boost and users. Panels Panels feature three or four people presenting their ideas and experiences relating to C++11 or C++14 and Boost's relevant, controversial, emerging, or unresolved issues. Panels may be conducted in several ways, such as comparative, analytic, or historic. Tutorials Tutorials are sessions at which instructors teach conference participants specific skills relevant to C++11 or C++14 and Boost. Workshops Workshops provide an active arena for advancements in Boost-relevant topics. Workshops provide the opportunity for experienced practitioners to develop new ideas about a topic of common interest and experience. Author's Corner Presentations These were introduced at BoostCon 2008, and were a great success. They are short (30 minute) sessions, focusing on tips on usage and design. In addition, we're looking to uncover the hidden design gems in Boost libraries. Tool Vendors Presentations We actively encourage tool vendors and ISP's to submit proposals for a special Tool Vendors Session Track aimed at products related to Boost and C++ (compilers, libraries, tools, etc.). Other formats may also be of interest. Don't hold back a proposal just because it doesn't fit into a pigeonhole. Submitting a proposal --------------------- Standard sessions are 90 minutes. You may submit a proposal for fractions or multiples of 90-minutes. Fractional proposals will be grouped into 90 minute sessions covering related topics. Longer sessions, such as tutorials and classes, will be assigned three hour (i.e. half day), or six hour (i.e. full day) time slots. Please include: * The working title. * Type of session: presentation, panel, tutorial, workshop, authors corner, vendor track, other. * A paragraph or two describing the topic covered, suitable for the conference web site. * Proposed length: 10-20 minute short talks, 45 minutes, 90 minutes, half day, full day. * Alternate lengths, if you are willing to make adjustments: 10-20 minute short-talks, 45 minutes, 90 minutes, half-day, full day. * Audience: users, developers, both. * Level: basic, intermediate, advanced. * A biography, suitable for the conference web site. * A photo of about 150 x 150 * Your public contact information (twitter handle, blog, website, google plus, etc.) * Your contact information (will not be made public). Submission details ------------------ All submissions should be made through the EasyChair conference management system: http://www.easychair.org/conferences/?conf=cppnow2014. If you have not already registered at EasyChair, you will need to do so in order to submit your proposal. All submissions will go through a peer review process.
