基于预留缓存的并发访问及多任务并行支撑技术研究

Research on Concurrent Data Access and Multi-Task Execution Support Technology Based on Reserved Cache

摘要:

在航天装备在役考核试验执行中,对于存在时空重叠的多个任务以及子任务,需要应用并行执行支撑技术。本文以典型航天装备在役考核综合评估任务为对象,从任务流层面和数据流层面,采用基于预留缓存的多线程并行并发技术,对多任务进行并行处理和执行。依托自主研发的航天装备在役考核综合评估系统,对本文方法进行了验证。系统运行结果表明,采用本文的多任务并行执行支撑技术可以高效快速地对大纲设计、数据采集等多个过程进行并发执行控制,对多源数据进行并行处理计算,有效提高了在役考核试验执行和综合评估的效率。

Abstract:

Multi-Task Concurrent Execution Technology (MTCET) is applied to support time-space-overlapped tasks and subtasks of analysis and evaluation for In-Service Inspection of Space Equipment. Concurrent technology based on Multi-thread and reserving cache is adapted to execute multi-task in the aspects of both task flow and data flow of overall assessment of Space Equipment. The method is verified based on the self-developed Overall Evaluating System of Space Equipment, whose result shows that several processes such as outline design and data collection can be concurrently executed and controlled effectively by applying presented multi-task concurrent execution technology, and multi-source data can be processed and calculated concurrently, which lifts the efficiency of in-service inspection test and overall evaluation.
