Chip Multi Processing aware Linux Kernel Scheduler

Recent advances in semiconductor manufacturing and engineering technologies have led to the inclusion of more than one CPU core in a single physical processor package. This, popularly know as Chip Multi Processing (CMP), allows multiple instruction streams to execute at the same time. CMP is in addition to today's Simultaneous Multi Threading (SMT) capabilities, like Intel Hyper-Threading Technology which allows a processor to present itself as two logical processors, resulting in best use of execution resources. With CMP, today's Linux Kernel will deliver instantaneous performance improvement. In this paper, we will explore ideas for further improving peak performance and power savings by making the Linux Kernel Scheduler CMP aware.
