A compositional parallel program is a program constructed by composing component programs in parallel, where the composed program inherits properties of its components. In this paper, we describe a small extension of C++ called Compositional C++ or CC++ which is an object-oriented notation that supports compositional parallel programming. CC++ integrates different paradigms of parallel programming: data-parallel, task-parallel and object-parallel paradigms;imperative and declarative programming;shared memory and message-based programs. CC++ is designed to be transportable across a range of MIMD architectures. © Springer-Verlag Berlin Heidelberg 1993.

My parallel-programming education began in earnest when I joined Sequent Computer Systems in late 1990. This education was both brief and effective: within a few short years, my co-workers and I were breaking new ground [MG92, MS93, MS98].1 Nor was I alone: Sequent habitually hired new-to-parallelism engineers and had them producing competent parallel code within a few months. Nevertheless, more than two decades later, parallel programming is perceived to be difficult to teach and learn. Is parallel programming an exception to the typical transitioning of technnology from impossible to expert-only to routine to unworthy of conscious thought? Copyright © 2012 ACM.

We present a set of primitive program schemes, which together with just two basic combining forms provide a suprisingly expressive parallel programming language. The primitive program schemes (called tropes) take the form of parameterised conditional rewrite rules, and the computational model is a variant of the Gamma style, in which computation proceeds by nondeterministic local rewriting of a global multiset. We consider a number of examples which illustrate the use of tropes and we study the algebraic properties of the sequential and parallel combining forms. Using the examples we illustrate the application of these properties in the verification of some simple program transformations. © Springer-Verlag Berlin Heidelberg 1993.

parallel programming is the future of computer science. Now days shift to parallel processing makes it even more useful. This research effort aims at helping parallelism education on real life target systems, using production oriented software tools. On its beginning, a survey of software environments for parallel programming is presented. The surveyed software environments are categorized according to their main function. An identity is synthesized for each environment by software and project attributes. Based on it and a set of proper criteria there are selected two groups of tools, those of primary and those of secondary interest for this research. An analysis of functional characteristics is performed for both groups. From the first group an open source software environment is chosen as the basis platform that will be enriched with education oriented enhancements. The characteristics analysis is exploited for the proposal of a research and development framework. Its target is the support of parallel programming, on real life target systems, using production oriented software environments. © 2010 IEEE.

parallel programming can provide higher computational performance over a sequential implementation by making use of the many cores available in parallel systems. However, the parallel-capable devices introduce complexity into the programming model. Current parallel programming API's such as OpenCL and CUDA provide interfaces to the parallel devices, but are complex and result in code which includes cross-cutting components, such as setting up the parallel programming context, compiling the parallel kernel, and transferring data between the host and device memory spaces when the kernel is executed. A C++ Aspect-Oriented based parallel programming (CAPP) framework is developed, using AspectC++ and OpenCL, which defines aspects to remove the cross-cutting components from the C++ code. The aspects set up the OpenCL context, compile the OpenCL kernel, and manage the data transfer between the memory spaces each time a kernel is executed. The aspects are woven into the C++ code before compilation, rather than at run time, which improves performance. An interface is provided for executing OpenCL kernels from the C++ code, essentially providing parallel programming in C++. The framework was applied to the SAXPY and Black-Scholes option pricing problems. Computational performance was, on average, 1.4-7% slower than the OpenCL implementation and up to 9 times faster than the sequential C++ implementation for the Black-Scholes problem. The amount of code was greatly reduced from the OpenCL implementation, and the resulting CAPP framework C++ code was simple and modular, resembling the sequential C++ implementation code. The amount of CAPP code required for the examples was found to be comparable to that of C++ AMP, another parallel programming framework. © 2015 ACM.

Structured parallel programming models based on parallel design patterns are gaining more and more importance. Several state-of-the-art industrial frameworks build on the parallel design pattern concept, including Intel TBB and Microsoft PPL. In these frameworks, the explicit exposition of parallel structure of the application favours the identification of the inefficiencies, the exploitation of techniques increasing the efficiency of the implementation and ensures that most of the more critical aspects related to an efficient exploitation of the available parallelism are moved from application programmers to framework designers. The very same exposition of the graph representing the parallel activities enables framework designers to emplace efficient autonomic management of non functional concerns, such as performance tuning or power management. In this paper, we discuss how autonomic management features evolved in different structured parallel programming frameworks based on the algorithmic skeletons and parallel design patterns. We show that different levels of autonomic management are possible, ranging from simple provisioning of mechanisms suitable to support programmers in the implementation of ad hoc autonomic managers to the complete autonomic managers whose behaviour may be programmed using high level rules by the application programmers. © 2019 IEEE.

parallel programming FOR A CHESS ENDGAME DATABASE

引用

SOFTWARE-PRACTICE & EXPERIENCE 1980年第6期10卷 475-487页

作者： MESSERSCHMIDT, HJ Department of Applied Mathematics University of the Witwatersrand Johannesburg South Africa

This paper presents a parallel implementation in APL of an algorithm to set up a database for the KR K -endgame in chess. It shows clearly the techniques necessary to achieve the parallelism and thereby proves that APL can be a valuable productivity increasing aid in this kind of Artificial Intelligence (AI)-research. The complete APL-functions are given in the Appendix. Both reversed pigeon hole and bit map techniques are used. Move generation is table driven with a new technique to cater for the blockage of sliding pieces like a rook. In order to maintain parallelism ‘if’ statements are avoided and extensive use is made of compression and identity elements.

Concurrent Collections (CnC)[8] is a declarative parallel language that allows the application developer to express their parallel application as a collection of high-level computations called steps that communicate via single-assignment data structures called items. A CnC program is specified in two levels. At the bottom level, an existing imperative language implements the computations within the individual computation steps. At the top level, CnC describes the relationships (ordering constraints) among the steps. The memory management mechanism of the existing imperative language manages data whose lifetime is within a computation step. A key limitation in the use of CnC for long-running programs is the lack of memory management and garbage collection for data items with lifetimes that are longer than a single computation *** the goal here is the same as that of classical garbage collection, the nature of problem and therefore nature of the solution is distinct. The focus of this paper is the memory management problem for these data items in CnC. We introduce a new declarative slicing annotation for CnC that can be transformed into a reference counting procedure for memory management. Preliminary experimental results obtained from a Cholesky example show that our memory management approach can result in space reductions for CnC data items of up to 28 relative to the baseline case of standard CnC without memory management. © 2009 ACM.
