Hybrid approach for scheduling on multicore processors that can effectively integrate the advantage of global scheduling and partitioning scheduling, becoming one of the hottest issues in real-time scheduling. Meanwhile, different from single-core, multicore architecture in the form of a variety of hierarchical shared caches, efficient cache usage on multicore platforms can greatly improve the scheduling efficiency. This paper proposes an improved hybrid approach for scheduling real-time tasks on multicore platforms, a multicore platform is partitioned into clusters that share a L2 cache, tasks which access a common region of memory are statically assigned to a same cluster, and those task are encouraged to co-scheduling in those cluster using improved global EDF algorithm. Simulation shows that this algorithm can improve the cache performance.
