Synopsis

This book delves into a problem in computer science - that of performance evaluation in computer systems - and proposes a sound methodology to address it. The author presents queuing network models as cost-effective tools for performance evaluation. The insights presented in this book enhance our understanding of priority scheduling models and their limitations, using shadow CPU-based techniques. The author provides an optimal approximation to the priority model, which is pessimistic for the performance of the high priority class and admits a product form solution. The book also includes a suboptimal model that is computationally efficient and outperforms the original shadow CPU technique.
