| 摘 要： | 为解决跨自治域的网络任务调度中的安全性和容错问题，提出了基于网格安全和容错的网格任务调度算法，并对用户任务的安全需求和资源的信任等级进行匹配，在系统安全等级较低且网络和主机可能失效的网格环境中进行容错任务调度。该算法根据网格系统的安全等级，自适应调整任务备份数，并对失败的任务重新调度。仿真结果表明，该算法可以有效提高不安全网格环境下的任务调度成功率，具有很好的容错性和可扩展性。

| Abstract: | To deal with security and fault-tolerant problems in network task scheduling cross administrative domains,a Security-Aware and Fault-Tolerant Scheduling(SAFTS) algorithm was proposed which scheduled the jobs by matching the user job's security demands and resource trust levels.In risky and failure-prone grids,SAFTS was robust due to its rescheduling mechanism and adaptive replication of jobs.Furthermore,the number of the replications of the jobs was changing adaptively according to the dynamic of grid secur... |
