Load balance scheduling for performance asymmetric multicore processors
XU Yuan-cha · Computer Engineering and Science · 2013
Given the same chip area,performance asymmetric multicore processor outperforms symmetric multicore processor in potential performance per watt.This requires reasonable operating system scheduling.To address this issue,based on Linux scheduling framework,a comprehensive heterogeneity-aware load balance policy is proposed.This policy can ensure load-balance-first and there is no need to define threshold to classify programs.The experimental result shows that both load balance and heterogeneity-aware are guaranteed.
