Abstract:Based on the base/deputy version of the technology,this paper proposed a fault-tolerant scheduling algorithm for a static process.It put forwarda new design model, proposed and analyzed the HDAL (heterogeneous distributed-system actual load) algorithm.Earlier a similar fault-tolerant scheduling algorithm for load-balancing to address the failure to sort through after the occurrence of load-balancing scheduling problem.The algorithm differed from the previous algorithm was not dependent sorting cases through the introduction of control of the process to solve the load balancing scheduling problem, and the algorithm was load balanced to a certain extent, with a controllable. Finally through simulation experiments,the following significant conclusions: busy in the business of heterogeneous systems HDAL algorithm resource-efficient than in the past has better load balancing, and scheduling speed advantages are obvious.......
