Efficient operating system scheduling for symmetric multi-core architectures in CPU scheduling”

Abstract

As multi-core architectures begin to emerge in every area of computing, operating system scheduling that takes the peculiarities of such architectures into account will become mandatory. Due to architectural differences to traditional multi-processors, such as shared caches, memory controllers and smaller cache sizes available per computational unit, it does not suffice to simply schedule tasks on multi-core processors in the same way as on SMP systems. It will be the responsibility of the operating system to spare the programmer as much platform-specific knowledge as possible and optimize overall performance by employing intelligent and configurable scheduling mechanisms. In this paper we will discuss about multi core architecture with the help of no. of scheduling mechanisms.
