Integrated Design and Performance Steering of Real-Time Systems

分布式实时系统通常非常复杂。它们由不同的系统组成，旨在执行受许多限制的任务，包括面对动态环境变化的时间限制。为了应对这些挑战，提出了一个统一的、可扩展的、基于编译器的复杂实时系统设计和工程框架，其研究目标如下：-设计一个系统工程框架，该框架包括一种系统规范语言和多种问题解决方法，以及它们之间的自动映射。-发现现有的用于并行和分布式、异类系统的在线性能可视化工具的共同属性，以及收集作为实时中间件的在线性能分析和可视化所需的属性。利用这些研究结果，设计一个全面的性能和分析框架，作为高级扩展的基础。-以便于复杂实时系统的在线系统操纵/重新配置的方式，将系统工程和在线性能和分析框架整合在一起。综合方法应该是半自动的，并允许对从目标系统收到的仪器数据进行算法和视觉分析，以利用解决问题的工具。

Distributed real-time systems are often very complex. They are composed of heterogeneous systems intended to perform tasks subject to many constraints, including time constraints in the face of dynamic environmental changes. In order to meet these challenges, a unifying, extensible, compiler-based framework is proposed for the design and engineering of complex real-time systems, with the following research objectives:- To devise a systems engineering framework that includes a systems specification language and multiple problem-solving approaches, as well as an automated mapping between them.- To discover common properties of extant on-line performance visualization tools for parallel and distributed, heterogeneous systems, as well as gather desired properties of the on-line performance analysis and visualization as a real-time middleware. Using the findings, to devise a comprehensive performance and analysis framework as a basis for advanced extensions.- To integrate the systems engineering and on-line performance and analysis frameworks in a way that facilities on-line system steering/reconfiguration of complex real-time systems. The integrated approach should be semi-automated, and allow algorithmic and visual analyses of instrumentation data received from the target system to utilize problem-solving tools.
