Visualization and analysis tools, techniques, and algorithms have undergone a rapid evolution in recent decades to accommodate explosive growth in data size and complexity and to exploit emerging multi- and many-core computational platforms. High Performance Visualization: Enabling Extreme-Scale Scientific Insight focuses on the subset of scientific visualization concerned with algorithm design, implementation, and optimization for use on today's largest computational platforms. The book collects some of the most seminal work in the field, including algorithms and implementations running at the highest levels of concurrency and used by scientific researchers worldwide. After introducing the fundamental concepts of parallel visualization, the book explores approaches to accelerate visualization and analysis operations on high performance computing platforms. Looking to the future and anticipating changes to computational platforms in the transition from the petascale to exascale regime, it presents the main research challenges and describes several contemporary, high performance visualization implementations. Reflecting major concepts in high performance visualization, this book unifies a large and diverse body of computer science research, development, and practical applications. It describes the state of the art at the intersection of scientific visualization, large data, and high performance computing trends, giving readers the foundation to apply the concepts and carry out future research in this area.

This book offers rides over the entire Lake Champlain region, from the southern tip of the lake at the birthplace of the U.S. Navy in Whitehall, New York, to its northernmost bay in Quebec, west to Lake Placid and extending east to the charming college town of Middlebury. Charles Hansen, who has been riding and organizing bicycle tours in the area for two decades, has researched and ridden these routes to create a book that will serve all cyclistsfrom the hardcore roadie who wants the challenge of an 82-mile ride through the eastern Adirondacks, to the casual rider or family looking for a scenic and largely flat afternoon outing. Several multiple day-tours are described, including the Lake Placid Weekender that starts from Burlington and provides a highly scenic and satisfying two-day ride for touring cyclists. Route notes are provided for The Grand Tour, a nine-day circumnavigation of the entire lake with a rest day in Montreal, as well as shorter variations on this tour. From 25 Bicycle Tours in the Lake Champlain Region you'll learn much about the rich history of the region as well as find out about tourism organizations, lodging, museums, and attractions along the way. 30 black & white photos, 25 maps.
