Title: Queuing model analysis of the Fujitsu VP2000 with dual scalar architecture

Abstract

This paper reports on a queuing model analysis which is given for the performance evaluation of a dual scalar processor (DSP), which is composed to two scalar units and one vector unit. The performance evaluation is the three different processor models with equivalent hardware capacity: homogeneous DSP (DSP1), heterogeneous DSP (DSP2), and multiprocessor (MP), with particular attention given to the case of short vector lengths. It is found that the performance of DSP1 is preferable to that of MP for most actual workloads, and in particular for the work-load of the Japan Atomic Energy Research Institute. The effect of the dual scalar capacity, that is, of attaching a secondary scalar unit, is also investigated. It is shown that the throughput of DSP1 is about 1.8 times that of the uniprocessor, for a vectorization ratio of 90%.
