Abstract
Energy conservation is an important issue. In a multi-core and multi-processor system, some system resources are shared by processors, such as memory and processor’s cache resources. When processors attempt to access shared resources at the same time, if processors cannot get the required shared resources immediately, it will result in the performance degradation and increased power consumption. In this paper, we have proposed a mechanism named energy-efficient scheduling which arranges tasks to run on processor cores in an appropriate way to avoid the access contention of shared resources and to save energy without sacrificing system performance too much.
The proposed energy-efficient scheduling is implemented in Linux kernel 2.6.33. The main work of implementation includes modification to the Linux kernel scheduler, the setting of the processor frequency, and the implementation of the system call for setting parameters of the system resources. Experimental results demonstrate that our energy-efficient scheduling can effectively save energy while avoiding the resource contention among processor cores to remain good performance.
