摘要
基于优先级的线程池模型为实时中间件提供控制处理器、网络和存储资源的手段和方法,是目前实时中间件中的研究重点.笔者从使用排队理论的分析模型对线程池进行模拟着手,分析了RTStarBus中基于优先级的线程池模型的局限性,提出了一种高效可适配的线程池模型.测试结果表明,该线程池模型能够灵活地适应更大范围的突发请求,可大大提高实时中间件处理大量突发请求的性能.
Thread pool model based on priority, since it's capable of providing methods to its control processor, network and saving resource has become a focus in the research of real-time middleware. After simulating thread pool using analysis model based on queue theory, the scarcity of thread pool based on priority in RTStarBus, was found out, and an efficient adaptive thread pool model was putforward. The result of the test indicated it is adaptive and flexible to wide ranging of concurrent request number, and could improve performance of the real-time middleware.
