Abstract:The frequency of CPU has boosted in recent years to meet the requirement of modern application on compute performance. However, the "Moore Law" can't be maintained only by increasing the frequency of single chip, the homogeneous multi-core system has appeared to compensate this insufficient. With the support of homogenous multi-core processors, the chip puts multiple processors with same status and structure together to minimize the cost of performance improving, load balancing and fault tolerance. The performance of parallel system is doubling when combining with appropriate software. In this paper, our research is focused on the multi-core task scheduling along with the changes in processor architecture from operating system level. The system uses hybrid scheduling which is composited of independent inter-cluster scheduling and unified inner-cluster scheduling. We do some deep analyzing on multi-core scheduling theory and implementation strategy from different aspects, including scheduling model, scheduling algorithm, dispatch algorithm and scheduling occasion. The experiment results prove the correctness and schedulability of the algorithms.
