Resource Proportional Software Design For Emerging Systems

Efficiency is a crucial concern across computing systems, from the edge to the cloud. Paradoxically, even as the latencies of bottleneck components such as storage and networks have dropped by up to four orders of magnitude, software path lengths have progressively increased due to overhead from the very frameworks that have revolutionized the pace of information technology. Such overhead can be severe enough to overshadow the benefits from switching to new technologies like persistent memory and low latency interconnects. Resource Proportional Software Design for Emerging Systems introduces resource proportional design (RPD) as a principled approach to software component and system development that counters the overhead of deeply layered code without removing flexibility or ease of development. RPD makes resource consumption proportional to situational utility by adapting to diverse emerging needs and technology systems evolution. Highlights: Analysis of run-time bloat in deep software stacks, an under-explored source of power-performance wastage in IT systems Qualitative and quantitative treatment of key dimensions of resource proportionality Code features: Unify and broaden supported but optional features without losing efficiency Technology and systems evolution: Design software to adapt with changing trade-offs as technology evolves Data processing: Design systems to predict which subsets of data processed by an (analytics or ML) application are likely to be useful System wide trade-offs: Address interacting local and global considerations throughout software stacks and hardware including cross-layer co-design involving code, data and systems dimensions, and non-functional requirements such as security and fault tolerance Written from a systems perspective to explore RPD principles, best practices, models and tools in the context of emerging technologies and applications This book is primarily geared towards practitioners with some advanced topics for researchers. The principles shared in the book are expected to be useful for programmers, engineers and researchers interested in ensuring software and systems are optimized for existing and next generation technologies. The authors are from both industry (Bhattacharya and Voigt) and academic (Gopinath) backgrounds.

This book addresses the question of how system software should be designed to account for faults, and which fault tolerance features should provide for highest reliability. With this third edition of Software Design for Resilient Computer Systems, the book is thoroughly updated to contain the newest advice regarding software resilience. With a new introductory chapter, the new edition is ideal for researchers and industry professionals. In the book, the authors first show how system software interacts with the hardware to tolerate faults. They analyze and further develop the theory of fault tolerance to understand the diverse ways to increase the reliability of a system, with special attention on the role of system software in this process. They introduce the theory of redundancy and its use for construction of a subsystem through generalised algorithm of fault tolerance (GAFT) and apply it to distributed systems. The book’s approach is applied to various hardware subsystems: different structures of RAM and processor cores and demonstrates exceptional performance reliability and energy efficiency. This third edition devotes substantial attention to system software for modern computers, including run time systems, supporting algorithms of recovery and their analysis, language aspects and ways to improve reconfigurable and parallel computing. Due to the wide-reaching nature of the content, this book applies to a host of industries and research areas, including military, aviation, intensive health care, industrial control, and space exploration.

This title allows students to do systems analysis and design right from the start. Examples and cases are drawn from actual systems projects that enable students to learn in the context of solving problems, much like the ones they will encounter on the job. A blend of traditional development and current techniques, such as client-server and object-oriented development, graphical user interfaces, and electronic data interchange are provided. The clear writing style makes systems analysis and design easy to understand.
