Linux 2.6 Fair Strategy Based Scheduler and Its Application Analysis
LU Jian-d · Microcomputer Information · 2010
Traditional Linux 2.4 schedulers existed some defects and several Linux 2.6 kernel distributions adopted either O (1) or CFS scheduler early and late,which obviously improving the original performance of CPU scheduling. Either O (1) or CFS scheduler has its own characteristics. This paper analyzed and compared these schedulers in depth,especially focused on parsing CFS scheduling. The implementation of various scheduling strategy and its appropriate application have also been thoroughly discussed by this author.
