一种基于监听-目录两层协议的一致性处理方法及系统
摘要:
本发明涉及计算机技术领域,特别涉及一种基于监听‑目录两层协议的一致性处理方法及系统。在CC‑NUMA系统中,Local节点中局部Cache一致性处理部件接收来自处理器的一次请求和Home节点的监听请求,一次请求和监听请求在各自的队列中向一致性处理流水线申请仲裁;轮转仲裁上流水线的一次请求或二次请求可进行地址冲突判断,无地址冲突的请求直接写入目录;写入目录的请求依据目录中存储的数据块副本状态和拥有者情况,对一次请求或监听请求进行局部一致性处理,由目录管理一次请求或监听请求所派生的二次请求、访存请求。本发明减少了资源冲突,快照处理不需要寄存请求内容、实现简单、减少硬件资源开销。(56)对比文件Qiong Li.A GPDMA-based DistributedShared I/O Solution for CC-NUMASystem.2008 The 9th InternationalConference for Young ComputerScientists.2008,全文.Daecheol You.Automotive Multi-ChipSystem with Cache Coherent Interconnectfor Pipelined Parallel Applications.2023IEEE International Conference on ConsumerElectronics (ICCE).2023,全文.John Chapin.Memory system performanceof UNIX on CC-NUMAmultiprocessors.Proceedings of the 1995ACM SIGMETRICS joint internationalconference on Measurement and modeling ofcomputer systems.1995,全文.Qiong Li等.A GPDMA-based DistributedShared I/O Solution for CC-NUMA System.2008 The 9th International Conference forYoung Computer Scientists.2008,全文.Daecheol You等.Automotive Multi-ChipSystem with Cache Coherent Interconnectfor Pipelined Parallel Applications.2023IEEE International Conference on ConsumerElectronics (ICCE).2023,全文.John Chapin等.Memory systemperformance of UNIX on CC-NUMAmultiprocessors.Proceedings of the 1995ACM SIGMETRICS joint internationalconference on Measurement and modeling ofcomputer systems.1995,全文.张峻等.CC-NUMA系统中一种块传输通讯机制的设计与实现.计算机工程与科学.2008,全文.刘妍等.多处理器高速缓存一致性分析与评价.科技信息(科学教研).2008,全文.
