Metascheduling: an elixir for performance-tuning of compound sessions based on the CM-resource model

Abstract

Continuous media (CM) applications have very critical performance requirements. System resources (CPU, file systems, networks etc) have to be steered to deliver maximum performance. However, a big question mark springs up when it comes to reservation of these resources in an efficient manner. The concept of metascheduling is proposed which serves non-real-time clients just as well as real-time ones. The quintessential pillar of metascheduling, the CM-resource model is captured to the core in this paper. This model extends a mathematical treatment to the concepts of 'workload' and 'delay', proposes a pseudo code for reservation of multi-resources and describes the necessaries of compound sessions and its parameters. This paper not only converges on performance but also focuses on CM-resource model's support to various communication topologies
