Chip Multi Processing aware Linux Kernel Scheduler

Recent advances in semiconductor manufactur-ing and engineering technologies have led to the inclusion of more than one CPU core in a single physical processor package. This, pop-ularly 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) capabil-ities, like Intel R © Hyper-Threading Technology which allows a processor to present itself as two logical processors, resulting in best use of ex-ecution 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.
