摘要

并行高性能计算作为许多应用程序的计算平台正在获得发展势头。近年来,并行计算机的软件支持研究主要集中在科学和信息处理应用方面。很少有人关注并行机器对实时嵌入式系统的要求。本文对并行计算机实时系统软件设计中的一些重要问题进行了探讨。本文讨论了并行体系结构上实时系统的形式化规范语言。为此,我们提出了并行实时规范语言(presel)。我们讨论了presel所基于的计算模型、它的语法、语义和适用性。presel通过提供结构化的时序结构、通信原语和显式并行结构扩展了现有的代数模型。

A specification language for parallel real-time systems
Parallel high-performance computing is gaining momentum as a computing platform for many applications. In recent years, the research in software support for parallel computers has mainly addressed scientific and information processing applications. Very little attention has been paid to real-time embedded system requirements on parallel machines. This research investigates some important issues related to designing real-time system software for parallel computers. In this paper, we discuss a formal specification language for real-time systems on parallel architectures. Towards this end we propose the Parallel REal Time SpEcification Language (PRETSEL). We discuss the computation model on which PRETSEL is based, its syntax, its semantics, and its applicability. PRETSEL extends existing algebraic models by providing structured timing constructs, communication primatives and explicit parallelism constructs.<>
