The STE||AR Group has released V0.9.8 of HPX -- A general purpose parallel C++ runtime system for applications of any scale.

HPX V0.9.8 Released

The newest version of HPX (V0.9.8) is now available for download! Please see here for the release notes.

HPX now exposes an API fully conforming to the concurrency related parts of the C++11 and the draft C++14 standards, extended and applied to distributed computing.

From the announcement:

• A large part of the code base of HPX has been refactored and partially re-implemented: the threading and networking subsystems have been improved in performance, modularity, and robustness, the API was improved for closer conformance to the concurrency related parts of the C++11 and C++14 draft standards and the upcomming Concurrency TS.
• We added new API functionality like hpx::migrate and hpx::copy_component which are the basic building blocks necessary for implementing higher level abstractions for system-wide load balancing, runtime-adaptive resource management, and object-oriented check-pointing and state-management.
• We improved the distributed reference counting scheme used by HPX which helps managing distributed objects and memory.

CppCon 2014 Registration Open: September 7-12, Bellevue, WA, USA

The Standard C++ Foundation is very pleased to announce the first annual CppCon.

Registration is now open for CppCon 2014 to be held September 7–12, 2014 at the Meydenbauer Center in Bellevue, Washington, USA. The conference will start with the keynote by Bjarne Stroustrup titled "Make Simple Tasks Simple!"

CppCon is the annual, week-long face-to-face gathering for all C++ users. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in the beautiful Seattle neighborhood and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.

What you can expect at CppCon:

• Invited talks and panels: The CppCon keynote by Bjarne Stroustrup will start off a week full of insight from some of the world’s leading experts in C++. Still have questions? Ask them at one of CppCon’s panels featuring those at the cutting edge of the language.

• Presentations by the C++ community: What do embedded systems, game development, high frequency trading, and particle accelerators have in common? C++, of course! Expect talks from a broad range of domains focused on practical C++ techniques, libraries, and tools.

• Lightning talks: Get informed at a fast pace during special sessions of short, less formal talks. Never presented at a conference before? This is your chance to share your thoughts on a C++-related topic in an informal setting.

• Evening events and “unconference” time: Relax, socialize, or start an impromptu coding session.

CppCon’s goal is to encourage the best use of C++. The conference is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to support the C++ software developer community and promote the understanding and use of modern, standard C++ on all compilers and platforms.

HPX version 0.9.7 released -- STE||AR Group, LSU

By Hartmut Kaiser | Nov 13, 2013 04:25 PM | Tags: performance parallelism distributed computing concurrency c++14 c++11

The STE||AR Group at Loisiana State University has released V0.9.7 of HPX -- A general purpose parallel C++ runtime system for applications of any scale.

HPX V0.9.7 Released

The newest version of HPX (V0.9.7) is now available for download! Over the past few months...

From the announcement:

• Ported HPX to BlueGene/Q
• Improved HPX support for Intel Xeon Phi® accelerators.
• Reimplemented hpx::bind, hpx::tuple, and hpx::function for better performance and better compliance with the C++11 Standard. Added hpx::mem_fn.
• Reworked hpx::when_all and hpx::when_any for better C++ compliance. Added hpx::when_any_swapped.
• Added hpx::copy as a precursor for a migrate functionality, added hpx::get_ptr allowing to directly access the memory underlying a given component.
• Added the hpx::lcos::broadcast, hpx::lcos::reduce, and hpx::lcos::fold collective operations.
• Added support for more flexible thread affinity control from the HPX command line, such as new modes (balanced, scattered, compact), improved default settings when running multiple localities on the same node.
• Added experimental executors for simpler thread pooling and scheduling. This API may change in the future as it will stay aligned with the ongoing C++ standardization efforts.
• Massively improved the performance of the HPX serialization code. Added partial support for zero copy serialization of array and bitwise-copyable types.
• General performance improvements of the code related to threads and futures.
