Study of the Model for Fault Tolerant Scheduling in Heterogeneous Distributed Real Time Systems

研究了基于异构分布式系统的实时容错调度算法 ,同构分布式系统中的处理机完全相同 ,而在异构分布式系统中各个处理机均不相同 ,各个处理机有不同的处理能力和不同的健壮性 .提出了可靠性成本概念 ,建立了一个基于异构分布式系统实时容错调度模型 .基于该模型 ,设计了一种实时容错调度算法 ,算法在不增加系统硬件成本的情况下 ,提高了实时分布式系统的可靠性 .

heterogeneous distributed systems have different processors and each processor has different capability and robusticity. The concept of reliability cost is presented, and a model of real time fault tolerant scheduling based on heterogeneous distributed systems given. A fault tolerant scheduling algorithms is also put forward, which can enhance the realiability of distributed system without increasing the cost of hardware.
