Abstract

Conventional process schedulers in operating systems control the sharing of the CPU resources among processes using a fixed scheduling policy, in which the utilization of a computer system (e.g., a real-time or a time-sharing system) is a major concern rather than content or behaviour of a process. As a result, the CPU resource is likely to be used in an inefficient manner, or the processing time of a process may be extended unnecessarily. Therefore, we proposed a process' behaviour-based scheduler in oder to reduce the processing time and the process switching cost. More specifically, our scheduler allows a process to continue its execution even though its time-slice has already expired, when it is predicted from an advanced knowledge called PFS (Program Flow Sequence) that the process needs a little bit more CPU time before it voluntarily relinquishes the CPU. In this paper, we present the experimental evaluation of our proposed scheduler.
