Transforming Real-Time Task Graphs to Improve Schedulability

标签：http   graph   insert   [1]   blog   bsp   model   art   ice   

Basic idea: 

insert artificial delays to the release times of certain vertices of a task graph to get a new graph with a smoother workload, while still meeting the timing constraints of the original task graph.

Contribution:

the proposed method can make a significant number of task systems that was originally unschedulable to become schedulable.

在这里，将job v3延后一个时间单元释放，使得不可调度的序列变为可调度。
