Multi-processor File-System Performance Modelling

The introduction of parallelism has brought forth new and diverse approaches to architecture and algorithm design. Furthermore, the measurement and prediction of performance, while varying the many design parameters, has become a more complex issue. In this paper we describe a simulation tool which is used to estimate the performance in an ongoing Parallel Database project. The tool consists of two major layers. In this paper we will focus on the file-system layer. This layer models current and future file-system configurations running on a multi-processor architecture. We illustrate the power of the tool by varying a small number of the tool's input parameters and demonstrating how they effect the system's performance. PROJECT BACKGROUND With the increased usage of Relational technology, the database user community is demanding highly usable and portable products, combined with acceptable performance. Database Decision Support applications, which involve considerable manipulation of ..
