The Group ( Systems Technology, Emergent Para llelism, and Algorithm Research) is an international research group with the goal of promoting the development of scalable parallel applications by providing a community for ideas, a framework for collaboration, and a platform for communicating these concepts to the broader community. The main contributors to HPX in the Group are researchers from 's and the 's.
For a full list of people working in this group and participating in writing this documentation see. This documentation is automatically generated for HPX (from Git commit: ) by the Boost and documentation tools.
And can be found in the collection of. The development of High Performance ParalleX ( HPX) started back in 2007. At that point, Hartmut Kaiser became interested in the work done by the ParalleX group at the, a multi-disciplinary research institute at.
The ParalleX group was developing a new and experimental execution model for future high performance computing architectures called ParalleX. The first implementations were crude at best, and we had to dismiss those designs entirely. However, over time we learned quite a bit about how to design a parallel distributed runtime system which implements the ideas of ParalleX.
Our goal is to create a high quality, freely available, open source implementation of the ParalleX model for conventional systems, such as classic Linux based Beowulf clusters or multi-socket highly parallel SMP nodes. At the same time, we want to have a very modular and well designed runtime system architecture which would allow us to port our implementation onto new computer system architectures.
We want to use real world applications to drive the development of the runtime system, coining out required functionalities and converging onto an stable API which will provide a smooth migration path for developers. The API exposed by HPX is modelled after the interfaces defined by the C11 ISO standard and adheres to the programming guidelines used by the collection of C libraries. From the very beginning, this endeavour has been a group effort. In addition to a handful of interested researchers, there have always been graduate and undergraduate students participating in the discussions, design, and implementation of HPX.
In 2011 we decided to formalize our collective research efforts by creating the group. Stands for Systems Technology, Emergent Para llelism, and Algorithm Research, which describes the three main focal points we center our work around. To learn more about and ParalleX, see. Some icons are used to mark certain topics indicative of their relevance.
These icons precede some text to indicate. We have had over 800 commits since the last release and we have closed over 65 tickets (bugs, feature requests, etc.). With the changes below, HPX is once again leading the charge of a whole new era of computation.
By intrinsically breaking down and synchronizing the work to be done, HPX insures that application developers will no longer have to fret about where a segment of code executes. That allows coders to focus their time and energy to understanding the data dependencies of their algorithms and thereby the core obstacles to an efficient code. Here are some of the advantages of using HPX.
HPX is solidly rooted in a sophisticated theoretical execution model - ParalleX. HPX exposes an API fully conforming to the C11 and the draft C14 standards, extended and applied to distributed computing.
Everything programmers know about the concurrency primitives of the standard C library is still valid in the context of HPX. It provides a competitive, high performance implementation of modern, future-proof ideas which gives an smooth migration path from todays mainstream techniques. There is no need for the programmer to worry about lower level parallelization paradigms like threads or message passing; no need to understand pthreads, MPI, OpenMP, or Windows threads, etc. There is no need to think about different types of parallelism such as tasks, pipelines, or fork-join, task or data parallelism.
The same source of your program compiles and runs on Linux, BlueGene/Q, Mac OS X, Windows, and Android. The same code runs on shared memory multi-core systems and supercomputers, on handheld devices and Intel® Xeon Phi™ accelerators, or a heterogeneous mix of those.
A major API breaking change for this release was introduced by implementing hpx:: future and hpx:: sharedfuture fully in conformance with the. While hpx:: sharedfuture is new and will not create any compatibility problems, we revised the interface and implementation of the existing hpx:: future. For more details please see the. To avoid any incompatibilities for existing code we named the type which implements the std:: future interface as hpx:: uniquefuture. For the next release this will be renamed to hpx:: future, making it full conforming to. A large part of the code base of HPX has been refactored and partially re-implemented.
The main changes were related to. The threading subsystem: these changes significantly reduce the amount of overheads caused by the schedulers, improve the modularity of the code base, and extend the variety of available scheduling algorithms. The parcel subsystem: these changes improve the performance of the HPX networking layer, modularize the structure of the parcelports, and simplify the creation of new parcelports for other underlying networking libraries.
The API subsystem: these changes improved the conformance of the API to, extend and unify the available API functionality, and decrease the overheads created by various elements of the API. The robustness of the component loading subsystem has been improved significantly, allowing to more portably and more reliably register the components needed by an application as startup. This additionally speeds up general application initialization. We added new API functionality like hpx:: migrate and hpx:: copycomponent which are the basic building blocks necessary for implementing higher level abstractions for system-wide load balancing, runtime-adaptive resource management, and object-oriented checkpointing and state-management. We removed the use of C11 move emulation (using Boost.Move), replacing it with C11 rvalue references. This is the first step towards using more and more native C11 facilities which we plan to introduce in the future. We improved the reference counting scheme used by HPX which helps managing distributed objects and memory.
This improves the overall stability of HPX and further simplifies writing real world applications. The minimal Boost version required to use HPX is now V1.49.0. This release coincides with the first release of (V0.1.0), the first implementation of the.
Here is a list of the important tickets we closed for this release. Ported HPX to BlueGene/Q. Improved HPX support for Xeon/Phi accelerators. Reimplemented hpx:: bind, hpx:: tuple, and hpx:: function for better performance and better compliance with the. Added hpx:: memfn.
Reworked hpx:: whenall and hpx:: whenany for better compliance with the ongoing C standardization effort, added heterogeneous version for those functions. Added hpx:: whenanyswapped. Added hpx:: copy as a precursor for a migrate functionality. Added hpx:: getptr 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 hpx:: getlocalityname allowing to retrieve the name of any of the localities for the application. Added support for more flexible thread affinity control from the HPX command line, such as new modes for - hpx: bind ( 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.
