Available in PDF, EPUB and Kindle. Book excerpt: Rotational position optimization disk scheduling algorithms utilize seek distance versus rotational distance information implemented as rpo tables (arrays) which are stored in flashmemory within each disk drive. We consider a novel representation scheme for this information reducing the required flashmemory by a factor of more than thirty thereby reducing the manufacturing cost per drive. We present simulation results showing the throughput for conservative and aggressive versions of the scheme as well as comparative results with the standard production drives not using these results.

Download or read book Aggressive Centralized and Distributed Scheduling of Disk Requests written by Bruce L. Worthington and published by . This book was released on 1995 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "Disk request scheduling is a critical element of high- performance computer system design. Previous disk scheduling research is insufficient because it uses simplistic or outdated disk models, unrepresentative workloads, and inadequate performance metrics. This dissertation explores the disk scheduler design space and provides guidelines for computer system engineers. Host-based and disk-based centralized scheduling are compared with distributed scheduling, a new paradigm with cost, complexity, and performance advantages. In distributed scheduling, individual disk schedulers located at multiple points along the I/O path cooperate to make scheduling decisions. Scheduler implementations are evaluated using a detailed simulator containing validated models of state-of-the-art host systems, controllers, buses, and disk drives. The simulator is driven with extensive traces of real-world system and disk activity, and it reports system performance metrics (e.g., application run times) in addition to traditional disk subsystem metrics (e.g., mean request response times). It is shown that for the best system performance, scheduling algorithms must incorporate system-level information (e.g., request priorities). Scheduling algorithms that focus on reducing seek delays do not need extensive disk-specific information. Finally, algorithms must exploit a disk's on-board cache to achieve the lowest disk service times. Additional guidelines are provided for dealing with disk drive command queues, sequential disk request optimizations, and different on-board cache configurations."

Book excerpt: Useful for Campus Recruitments, UGC-NET and Competitive Examinations— ISRO, DRDO, HAL, BARC, ONGC, NTPC, RRB, BHEL, MTNL, GAIL and Others 28 Years’ GATE Topic-wise Problems and Solutions In today’s competitive scenario, where there is a mushrooming of universities and engineering colleges, the only yardstick to analyze the caliber of engineering students is the Graduate Aptitude Test in Engineering (GATE). It is one of the recognized national level examination that demands focussed study along with forethought, systematic planning and exactitude. Postgraduate Engineering Common Entrance Test (PGECET) is also one of those examinations, a student has to face to get admission in various postgraduate programs. So, in order to become up to snuff for this eligibility clause (qualifying GATE/PGECET), a student facing a very high competition should excel his/her standards to success by way of preparing from the standard books. This book guides students via simple, elegant and explicit presentation that blends theory logically and rigorously with the practical aspects bearing on computer science and information technology. The book not only keeps abreast of all the chapterwise information generally asked in the examinations but also proffers felicitous tips in the furtherance of problem-solving technique. Various cardinal landmarks pertaining to the subject such as theory of computation, compiler design, digital logic design, computer organisation and architecture, computer networks, database management system, operating system, web technology, software engineering, C programming, data structure, design and analysis of algorithms along with general aptitude verbal ability, non-verbal aptitude, basic mathematics and discrete mathematics are now under a single umbrella. HIGHLIGHTS OF THE BOOK • Systematic discussion of concepts endowed with ample illustrations • Adequate study material suffused with pointwise style to enhance learning ability • Notes are incorporated at several places giving additional information on the key concepts • Inclusion of solved practice exercises for verbal and numerical aptitude to guide the students from practice and examination point of view • Points to ponder are provided in between for a quick recap before examination • Prodigious objective-type questions based on the GATE examination from 1987 to 2014 along with in-depth explanation for each solution from stem to stern • Every solution lasts with a reference, thus providing a scope for further study • Two sample papers for GATE 2015 are incorporated along with answer keys WHAT THE REVIEWERS SAY “Professor Dasaradh has significantly prepared each and every solution of the questions appeared in GATE and other competitive examinations and many individuals from the community have devoted their time to proofread and improve the quality of the solutions so that they become very lucid for the reader. I personally find this book very useful and only one of its kind in the market because this book gives complete analysis of the chapterwise questions based on the previous years’ examination. Moreover, all solutions are fully explained, with a reference to the concerned book given after each solution. It definitely helps in the elimination of redundant topics which are not important from examination point of view. So, the students will be able to reduce the volume of text matter to be studied. Besides, solutions are presented in lucid and understandable language for an average student.” —Dr. T. Venugopal, Associate Professor, Department of CSE, JNTUH, Jagtial “Overall, I think this book represents an extremely valuable and unique contribution to the competitive field because it captures a wealth of GATE/PGECET examination’s preparation experience in a compact and reusable form. This book is certainly one that I shall turn into a regular practice for all entrance examinations’ preparation guides. This book will change the way of preparation for all competitive examinations.” —Professor L.V.N. Prasad, CEO, Vardhaman College of Engineering, Hyderabad “I began to wish that someone would compile all the important abstracting information into one reference, as the need for a single reference book for aspirants had become even more apparent. I have been thinking about this project for several years, as I have conducted many workshops and training programs. This book is full of terms, phrases, examples and other key information as well as guidelines that will be helpful not only for the students or the young engineers but also for the instructors.” —Professor R. Muraliprasad, Professional Trainer, GATE/IES/PSU, Hyderabad The book, which will prove to be an epitome of learning the concepts of CS and IT for GATE/PGECET examination, is purely intended for the aspirants of GATE and PGECET examinations.

Book excerpt: Over the past two decades, there has been a huge amount of innovation in both the principles and practice of operating systems Over the same period, the core ideas in a modern operating system - protection, concurrency, virtualization, resource allocation, and reliable storage - have become widely applied throughout computer science. Whether you get a job at Facebook, Google, Microsoft, or any other leading-edge technology company, it is impossible to build resilient, secure, and flexible computer systems without the ability to apply operating systems concepts in a variety of settings. This book examines the both the principles and practice of modern operating systems, taking important, high-level concepts all the way down to the level of working code. Because operating systems concepts are among the most difficult in computer science, this top to bottom approach is the only way to really understand and master this important material.
