Abstract: "Memory latency is becoming an increasingly important performance bottleneck, especially in multiprocessors. One technique for tolerating memory latency is multithreading, whereby we switch between threads upon expensive cache misses. In contrast with previous work on multithreading, we explore a new approach that is software-controlled rather than hardware-controlled. To implement software-controlled multithreading, we use informing memory operations to quickly trap upon cache misses to a miss handler which performs the actual thread switching in software. Our experimental results demonstrate that software-controlled multithreading can result in significant performance gains on a shared-memory multiprocessor, with the majority of applications speeding up by 10% or more, and one application speeding up by 16%. In addition, we find that by selectively applying a register partitioning optimization to reduce the thread-switching overhead, we can increase the overall speedups to as much as 25%. Given the much simpler hardware support required by our scheme, and the fact that its software overheads are expected to become less and less expensive over time relative to memory latencies, software-controlled multithreading is [sic] attractive alternative to traditional hardware-based schemes."

This book aims at developing a reader’s thorough understanding of the challenges and opportunities of two categories of networks, namely k-covered wireless sensor networks and k-barrier covered wireless sensor networks. It presents a variety of theoretical studies based on percolation theory, convexity theory, and applied computational geometry, as well as the algorithms and protocols that are essential to their design, analysis, and development. Particularly, this book focuses on the cover, sense, and inform (CSI) paradigm with a goal to build a unified framework, where connected k-coverage (or k-barrier coverage), sensor scheduling, and geographic data forwarding, gathering, and delivery are jointly considered. It provides the interested reader with a fine study of the above networks, which can be covered in introductory and advanced courses on wireless sensor networks. This book is useful to senior undergraduate and graduate students in computer science, computer engineering, electrical engineering, information science, information technology, mathematics, and any related discipline. Also, it is of interest to computer scientists, researchers, and practitioners in academia and industry with interest in these two networks from their deployment until data gathering and delivery.
