Fault-tolerance rotational scheduling algorithm of real-time tasks in heterogeneous distributed systems
Kailong Zhang · 2008
A real-time scheduling model which includes some formal descriptions of heterogeneous tasks and processor resources is stu-died and presented in distributed systems.A rotational scheduling algorithm is brought forth based on the primary copy/backup redundant technique.The simulation experiment illustrates that the algorithm effectively improved utilization ratio of resources and enhanced the overall performance of the heterogeneous distributed systems.
