| 摘 要： | 同时多线程处理器允许多个线程同时执行,一方面提高了处理器的性能,另一方面也为通过线程冗余执行来容错提供了支持.冗余多线程结构将线程复制成两份,二者独立执行,并比较结果,从而实现检错或者容错.冗余多线程结构主要采用ICOUNT调度策略来解决线程间资源共享问题.然而这种策略有可能造成"饥饿"现象,并降低处理器吞吐率.提出一...

| Abstract: | The simultaneous multithreading technique permits multiple issues from different threads simultaneously,which provides nature support for fault-tolerance by executing threads redundantly.Redundant multithreading(RMT)copies each thread into two copies that performances independently,and the corresponding results from the two threads are compared for detecting or tolerating faults.Most RMT structures adopt ICOUNT thread scheduling,which may suffer from long instruction latency.Long latency instructions may st... |
