The STE||AR Group has released V1.4 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.4 Released

The newest version of HPX (V1.4) is now available for download! This release focuses on performance and stability improvements. Please see here for the full release notes.

    HPX is a general purpose parallel C++ runtime system for applications of any scale. It implements all of the related facilities as defined by the C++ Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 parallel algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the C++ Concurrency TS, Parallelism TS V2, data-parallel algorithms, executors, and many more. It also extends the existing C++ Standard APIs to the distributed case (e.g. compute clusters) and for heterogeneous systems (e.g. GPUs).

    HPX seamlessly enables a new Asynchronous C++ Standard Programming Model that tends to improve the parallel efficiency of our applications and helps reducing complexities usually associated with parellism and concurrency.

HPX version 0.9.99 released -- STE||AR Group

By Hartmut Kaiser | Jul 18, 2016 05:28 AM | Tags: performance parallelsim heterogeneous computing distributed computing c++17 c++14 c++11

The STE||AR Group has released V0.9.99 of HPX -- A general purpose parallel C++ runtime system for applications of any scale.

HPX V0.9.99 Released

The newest version of HPX (V0.9.99) is now available for download! Please see here for the release notes.

HPX exposes an API fully conforming to the concurrency related parts of the C++11/C++14/C++17 standards, extended and applied to distributed and heterogeneous computing, and aligned with the ongoing standardization discussions.

From the announcement:

• Version 1.0 approaches! This release is significant as HPX is nearly feature complete. Over the next several months we will continue to test and polish HPX’s API and documentation. The feedback and experience gained from the community’s utilization of this release will provide guidance on where to add the finishing touches for V1.0.
• We have put a lot of effort into improving the overall performance and stability of the library. Applications written using HPX have shown to outperform equivalent applications which are based on more conventional parallelization methods.
• In this release we finished the implementation of transparent migration of components to another locality (e.g. physical compute-node). It is now possible to trigger a migration operation without ‘stopping the world’ for the object to migrate. HPX will make sure that no work is being executed on the object while it is moved and that all subsequently scheduled work for the migrated object will be transparently forwarded to the new locality. The global address of the migrated object does not change, thus the application will not have to be changed in any way to support this new functionality.

HPX version 0.9.11 released -- STE||AR Group

By Hartmut Kaiser | Nov 13, 2015 05:32 AM | Tags: performance parallelism experimental distributed computing c++14 c++11

The STE||AR Group has released V0.9.11 of HPX -- A general purpose parallel C++ runtime system for applications of any scale.

HPX V0.9.11 Released

The newest version of HPX (V0.9.11) is now available for download! Please see here for the release notes.

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

From the announcement:

• In this release our team has focused on developing higher level C++ programming interfaces which simplify the use of HPX in applications and ensure their portability in terms of code and performance. We paid particular attention to align all of these changes with the existing C++ Standard or with the ongoing standardization work. Other major features include the introduction of executors and various policies which enable customizing the ‘where’ and ‘when’ of task and data placement.
• This release consolidates many of the APIs exposed by HPX. We introduced a new uniform way of creating (local and remote) objects, we added distribution policies allowing to manage and customize data placement and migration, we unified the way various types of parallelism are made available to the user.

HPX version 0.9.8 released -- STE||AR Group

By Hartmut Kaiser | Mar 24, 2014 02:57 PM | Tags: performance parallelism distributed computing concurrency c++14 c++11

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.
