Abstract : The objective of this study is to assess the applicability of analytic techniques to the INFOPLEX database computer. This report builds on earlier work which has used simulation to evaluate the performance of the INFOPLEX data storage hierarchy. Simulation, though accurate, is not cost effective for exploring different design alternatives. Preliminary results from this study indicate that cost effective tools can be developed to analyze different architecture designs so that optimal design alternatives can be identified early in the design process. The model used in this report produces ceiling throughput to systems under investigation for overhead due to unbalanced flow is ignored. Tighter bounds can be obtained by including the unbalanced flow into analytic models. (Author)
