An Approach to the GRM Performance Analysis by Asymptotic Approximation

概要

An approach is presented to analyze the performance of a system with the General Resources Manager(GRM). The GRM is a periodical modifier of resource allocation priorities for throughput/response improvements in multiprogrammed computer systems. Because of the complexity, its scheduling effect has so far been investigated by only simulations or measurements. This paper first considers the system with constant priorities and develops a new approximation technique, termed the Asymptotic Model. Simulations results show the validity of the model for the prediction of response times under priority scheduling disciplines and limited degree of multiprogramming. Secondly, based on the model, the control policy of the GRM is discussed. Furthermore a way to predict the performance under the GRM control policy is introduc0d. The approach presented reveals very little of GRM's dynamic behavior. For the full analysis of the GRM much work remains to be done. However, some essential properties of the GRM are considered successfully demonstrated by the use of the model.
