" "This is the first book that promises to tell the deep, dark secrets of computer arithmetic, and it delivers in spades. It contains every trick I knew plus many, many more. A godsend for library developers, compiler writers, and lovers of elegant hacks, it deserves a spot on your shelf right next to Knuth.""--Josh Bloch" "When I first saw the title, I figured that the book must be either a cookbook for breaking into computers (unlikely) or some sort of compendium of little programming tricks. It's the latter, but it's thorough, almost encyclopedic, in its coverage." "--Guy Steele These are the timesaving techniques relished by computer hackers--those devoted and persistent code developers who seek elegant and efficient ways to build better software. The truth is that much of the computer programmer's job involves a healthy mix of arithmetic and logic. In "Hacker's Delight," veteran programmer Hank Warren shares the tricks he has collected from his considerable experience in the worlds of application and system programming. Most of these techniques are eminently practical, but a few are included just because they are interesting and unexpected. The resulting work is an irresistible collection that will help even the most seasoned programmers better their craft. Topics covered include: A broad collection of useful programming tricks Small algorithms for common tasksPower-of-2 boundaries and bounds checkingRearranging bits and bytesInteger division and division by constantsSome elementary functions on integersGray codeHilbert's space-filling curveAnd even formulas for prime numbers! This book is for anyone who wants to create efficient code. "Hacker's Delight" will help you learn to program at a higher level--well beyond what is generally taught in schools and training courses--and will advance you substantially further than is possible through ordinary self-study alone. 0201914654B06272002

This book is an all-in-one source of information for programming the Second-Generation Intel Xeon Phi product family also called Knights Landing. The authors provide detailed and timely Knights Landingspecific details, programming advice, and real-world examples. The authors distill their years of Xeon Phi programming experience coupled with insights from many expert customers Intel Field Engineers, Application Engineers, and Technical Consulting Engineers to create this authoritative book on the essentials of programming for Intel Xeon Phi products. "Intel(r) Xeon Phi Processor High-Performance Programming" is useful even before you ever program a system with an Intel Xeon Phi processor. To help ensure that your applications run at maximum efficiency, the authors emphasize key techniques for programming any modern parallel computing system whether based on Intel Xeon processors, Intel Xeon Phi processors, or other high-performance microprocessors. Applying these techniques will generally increase your program performance on any system and prepare you better for Intel Xeon Phi processors. A practical guide to the essentials for programming Intel Xeon Phi processorsDefinitive coverage of the Knights Landing architecturePresents best practices for portable, high-performance computing and a familiar and proven threads and vectors programming modelIncludes real world code examples that highlight usages of the unique aspects of this new highly parallel and high-performance computational productCovers use of MCDRAM, AVX-512, Intel(r) Omni-Path fabric, many-cores (up to 72), and many threads (4 per core)Covers software developer tools, libraries and programming modelsCovers using Knights Landing as a processor and a coprocessor"
