摘　　要：在总结各种体系结构级容错措施的技术特点以及目前的研究现状和发展趋势的基础上,论述了冗余多线程(RMT)体系结构研究的时代背景、典型架构设计方法和存在的问题,以及今后研究的方向和发展趋势.提出了今后应该从资源分配和线程调度的角度对RMT进行研究,提升其整体处理能力,包括:提高RMT的容错能力;降低容错运行所需要的软、硬件代价;以及提高资源利用的效率和公平性,缓解多线程并行对资源需求的巨大压力.The technical features and research tendencies of various architectural level fault-tolerant schemes are summarized first,based on which,a systemic discourse upon the redundant multithreading（RMT） architecture is presented from the aspects of its background,typical design and problems,research directions and development tendencies.Investigating the RMT from the view of resource allocating and thread scheduling is proposed so as to boost the overall performance,including： enhancing the fault-tolerant ability,reducing the software and hardware implementation cost and improving the efficiency,elevating the resource efficiency and fairness,and alleviating the huge resource pressure caused by multiple threads.
