摘要

本文介绍了一种新的用于并行程序设计的高级控制机制。特殊的同步器进程收集有关应用程序并行进程状态的信息，并使用时间间隔时间戳构造强一致的全局状态。基于一致的全局状态，同步器评估同步和执行控制谓词。因此，同步/控制信号被发送到应用程序进程。这些信号可以触发异步计算的激活或取消。所提出的同步框架与消息传递系统集成，并包含在GRADE图形并行程序设计环境中。讨论了该系统的体系结构和实现方法。

Graphical design tool for parallel programs with execution control based on global application states

New high-level control mechanisms for design of parallel programs are introduced in the paper. Special synchronizer processes collect information on application parallel process states and construct strongly consistent global states, using time interval timestamps. Based on consistent global states, synchronization and execution control predicates are evaluated by the synchronizers. As a result, synchronization/control signals are sent to application processes. The signals can trigger asynchronous computation activation or cancellation. The proposed synchronization framework is integrated with a message passing system and included into GRADE graphical parallel program design environment. Architecture and implementation aspects of such system are discussed.
