ParM:基于国产处理器的异构并行编程模型

随着算力需求的增长，各种国产异构计算设备不断出现，这些设备都有其专用的编程模型，开发者需要根据不同设备的架构特点在专用的编程模型上进行开发，导致开发出的代码在设备间不具有可移植性。近年来国外已经出现了支持多种计算设备的统一异构并行编程模型，但针对国产设备的异构编程模型的研究和实现还比较少。针对该问题，开发了一套性能可移植的异构编程模型ParM。该编程模型以C++库的形式提供，屏蔽了大量的底层实现细节，降低了并行编程难度。该编程框架目前支持的后端设备有x86 CPU、NVIDIA GPU、华为鲲鹏处理器和华为昇腾AI处理器，并且对各种后端设备进行了性能优化。在各种设备上的性能测试表明，ParM编程模型的性能可以达到原始代码的90%以上。

适合机群OpenMP系统的制导扩展

OpenMP以其易用性和支持增量并行的特点成为共享存储体系结构的编程标准．机群OpenMP系统在机群上实现了OpenMP计算环境，它将OpenMP的易编程性和机群的可扩展性结合起来，是很有意义的．OpenMP的编程方式主要有循环级和SPMD两种，其中循环级方式易于编程而SPMD方式难于编程．然而在机群OpenMP系统中获得高性能OpenMP程序，必需采用SPMD方式．该文描述了适合机群OpenMP系统的一个简单的OpenMP制导扩展子集(包括数据分布制导、循环调度模式)，并在机群OpenMP系统OpenMP／JIAJIA上进行了实现．应用测试表明，利用这些制导扩展进行编程，既保持循环级方式的易编程性又获得与SPMD方式相当的性能，是有效的编程方式．

Visual programming with analogical representations: Inspirations from a semiotic analysis of comics

Analogical representations based on pictures of domain objects can be used in visual programming to provide a close mapping between the program and the resulting runtime display, which can make programming easier for children and other users. The use of graphical rewrite rules with before and after pictures is an example of this approach. Graphical rewrite rules have some similarities with comics strips, which also use picture sequences of graphical objects to describe dynamics in a static form. However, the visual language of comics is not used to its full potential in visual programming. We discuss how a semiotic analysis of comics can be used to address some of the limitations of graphical rewrite rules. We use a visual programming system we have designed to illustrate that comic strips can express more general computations and be more intuitive and flexible than traditional graphical rewrites. Our conclusion is that the visual language of comics has a strong potential for increasing the expressiveness and flexibility of visual programming with analogical representations of domain objects, while maintaining a direct mapping between the program representation and the runtime representation.

DPOS: A metalanguage and programming environment for parallel processing

This paper describes and illustrates a structured programming metalanguage (DPOS) and graphical programming environment for generating and debugging high-level distributed MIMD parallel programs. DPOS introduces an innovative message-passing model and also recursive graphical definition of parallel process networks. It also provides programming and debugging at the meta language level that is portable across implementation languages. The initial development focus of DPOS is to provide a parallel development system for Lisp-based, symbolic and artificial intelligence programs as part of the MAYFLY parallel processing project. The DPOS environment also generates source code and provides a simulation system for graphical debugging and animation of the programs in graph form.

Avoiding Knotty Structures in Design: Schematic Functional Programming

Designers in general have used diagrams and sketches to help in the process of creation. This is particularly so for system designers whose output is a set of programs. It would seem reasonable that the conversion of diagrams directly into a program would be desirable and yet the work of Green and Petre [3–4, 13] and Citrin [2] has placed doubt on the viability of graphical programming notations. Some of this work is reviewed in this paper. The use of secondary notation and the matc–mismatch hypothesis is reconsidered in the light of functional programming. It is proposed that much of the criticism of graphical notation is due to the imperative (or process orientated) nature of programming. Many of the limitations observed in using graphical notation are lifted when functional programming is used. Eight engineering dimensions and four engineering relationships (coherences) are proposed to describe programming environments (including notation). The source of ‘knotty structures’ is identified as embedded ‘if then else’ or ‘if’ statements. On analysing both imperative and functional programs it was found that imperative programs used an order of magnitude larger number of ‘if’s than functional programs. The key to the success of a functional language as a general representation as well as its coherence with a graphical notation comes from its unique extensibility. Support for these arguments is drawn from examples of a schematic programming language used for industrial scale projects. It is concluded that the marriage between a functional language and its graphical representation overcomes most of the original criticisms of graphical programming. It is demonstrated that this combination makes a viable and expressive tool for industrial-sized applications.     

A graphical development and debugging environment for parallel programs

To provide high-level graphical support for PVM (Parallel Virtual Machine) based program development, a complex programming environment (GRADE) is being developed. GRADE currently provides tools to construct, execute, debug, monitor and visualize message-passing parallel programs. It offers a high-level graphical programming abstraction mechanism to construct parallel applications by introducing a new graphical language called GRAPNEL. GRADE also provides the programmer with the same graphical user interface during the program design and debugging stages. A distributed debugging engine (DDBG) assists the user in debugging GRAPNEL programs on distributed memory computer architectures. Tape/PVM and PROVE support the performance monitoring and visualization of parallel programs developed in the GRADE environment.
