Abstract

This paper extends a previous model for computer system configuration planning developed by the authors. The problem is to optimally select the CPU speed, the device capacities, and file assignments so as to maximize throughput subject to a fixed cost constraint. We advocate solving this essentially discrete problem in continuous variables followed by an appropriate discretization. The discretization error thus committed is analyzed in detail.
