Available in PDF, EPUB and Kindle. Book excerpt: As disk arrays become widely used, tools for modeling and analyzing the performance of disk arrays become increasingly important. In particular, accurate performance models and systematic analysis techn iques, combined with a thorough understanding of the expected workload, are invaluable in both configuring and designing disk arrays. Unfortunately, disk arrays, like many parallel systems, are difficult to model and analyze because of \fIqueueing\fR and \fIfork-join synchron ization\fR. In this dissertation, we present an analytic performance model for non- redundant disk arrays and a new technique based on \fIutilization profiles\fR for analyzing the performance of redundant disk arrays. In both cases, we provide applications of our work. We use the analytic model to derive an equation for the optimal size of data striping in disk arrays, and we apply utilization profiles to analyze the performance of RAID- II, our second disk array prototype. The results of the analysis are used to answer several performance related questions about RAID-II and to compare the performance of RAID-II to RAID-I, our first disk array prototype.

Download or read book Performance Modeling for Computer Architects written by C. M. Krishna and published by John Wiley & Sons. This book was released on 1995-10-14 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: As computers become more complex, the number and complexity of the tasks facing the computer architect have increased. Computer performance often depends in complex way on the design parameters and intuition that must be supplemented by performance studies to enhance design productivity. This book introduces computer architects to computer system performance models and shows how they are relatively simple, inexpensive to implement, and sufficiently accurate for most purposes. It discusses the development of performance models based on queuing theory and probability. The text also shows how they are used to provide quick approximate calculations to indicate basic performance tradeoffs and narrow the range of parameters to consider when determining system configurations. It illustrates how performance models can demonstrate how a memory system is to be configured, what the cache structure should be, and what incremental changes in cache size can have on the miss rate. A particularly deep knowledge of probability theory or any other mathematical field to understand the papers in this volume is not required.

Download or read book Analytical Performance Modeling for Computer Systems Third Edition written by Tay Y.C. and published by Springer Nature. This book was released on 2022-06-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to analytical performance modeling for computer systems, i.e., writing equations to describe their performance behavior. It is accessible to readers who have taken college-level courses in calculus and probability, networking, and operating systems. This is not a training manual for becoming an expert performance analyst. Rather, the objective is to help the reader construct simple models for analyzing and understanding the systems that they are interested in. Describing a complicated system abstractly with mathematical equations requires a careful choice of assumptions and approximations. They make the model tractable, but they must not remove essential characteristics of the system, nor introduce spurious properties. To help the reader understand the choices and their implications, this book discusses the analytical models for 40 research papers. These papers cover a broad range of topics: GPUs and disks, routers and crawling, databases and multimedia, worms and wireless, multicore and cloud, security and energy, etc. An appendix provides many questions for readers to exercise their understanding of the models in these papers.
