多处理机系统的一种实时容错调度算法

A Real-Time Fault-Tolerance Scheduling Algorithm in Multiprocessor Systems

实时容错调度算法是实时系统容错研究中的重要问题。提出了一种多处理机系统的实时任务容错调度算法.该算法结合了基版本/副版本(Primary/Backup)方法和三模冗余(TMR)方法,以保证在一个节点机失效时,任务可以在其截止时限内完成。

Real -Time Fault- Tolerance Scheduling Algorithm is an important problem in fault- tolerance studies of real - time system. A fault - tolerance scheduling algorithm for real - time tasks is presented in this paper. It consists of Primary/Backup and TMR and can generate schedules that can tolerate one processor failure.
