Predictable Management of System Resources for Linux

Overview

In current operating systems, a process acts both as a protection domain and as a resource principal. This paper tries to investigate how this model fits into a Linux framework, especially, in the soft real time context. It shows that this model allows to allocate resources in a predictable manner and hence can be used for scheduling soft real-time tasks like multimedia. This paper also provides a framework in Linux which allows privileged users to have their own schedulers for scheduling a group of activities so that they can make use of the domain knowledge about the applications.
