Summary:On CMP, programs commonly interference with each other. But for programs co-running on CMP, serious performance dropdown is not expected. With the growth of the program’s size, program’s contention for limited shared resources in the system will become increasingly intense, and the resulting impact on system performance will be even more pronounced. How to allocate and share limited shared resources among programs is a very important problem. In this paper we propose a new method to ensure the fairness of program’s performance on CMP. The share resource CPU and memory are included in our study. Meanwhile, the Linux resource management tool Cgroups is used to realize our idea. By the resource we profiled and the tool support, we realize a reasonable resource dividing method to ensure the fairness of program’s performance. The reasonable resource dividing method include three Engine. The experiment result show that making use of the fairness resource dividing method proposed by our paper, compared with operating system scheduling, program’s performance difference can be largely reduced.
