Abstract:

A new heuristic process scheduling strategy was proposed on the basis of a memory sharing mechanism. Based on software defined networking (SDN) architecture, A workload model and a memory energy consumption model were designed. Two heuristic process scheduling algorithms were designed to save the memory energy consumption. The algorithms come from physical memory nodes. The key idea of the above proposed algorithms is to achieve the largest sharing ratio of memory which assures workload balance through scheduling processes reasonably. The least number of active memory nodes means the least memory energy consumption of data center. Simulations verify that these strategies can reduce the energy consumption effectively.

Key words: memory energy consumption, software defined networking, process sheduling algorithm
