Design of a process scheduler with guaranteed resource allocation

Cluster computing and multimedia are two different classes of applications emerging in recent general computing development. However, such application poses different kind of requirement on processing power where traditional time-sharing process schedulers could not deliver. Processing power delivery in such scheduler is not guaranteed neither in terms of amount nor timing. To cope with this, a process scheduler with guaranteed service has to be employed. In this paper, we will present the design of a guaranteed process scheduler by adapting the concept of contractual computing.
