Download or read book Parallel R written by Q. Ethan McCallum and published by "O'Reilly Media, Inc.". This book was released on 2011-10-21 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: It’s tough to argue with R as a high-quality, cross-platform, open source statistical software product—unless you’re in the business of crunching Big Data. This concise book introduces you to several strategies for using R to analyze large datasets, including three chapters on using R and Hadoop together. You’ll learn the basics of Snow, Multicore, Parallel, Segue, RHIPE, and Hadoop Streaming, including how to find them, how to use them, when they work well, and when they don’t. With these packages, you can overcome R’s single-threaded nature by spreading work across multiple CPUs, or offloading work to multiple machines to address R’s memory barrier. Snow: works well in a traditional cluster environment Multicore: popular for multiprocessor and multicore computers Parallel: part of the upcoming R 2.14.0 release R+Hadoop: provides low-level access to a popular form of cluster computing RHIPE: uses Hadoop’s power with R’s language and interactive shell Segue: lets you use Elastic MapReduce as a backend for lapply-style operations

Download or read book Parallel Programming written by Thomas Rauber and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Innovations in hardware architecture, like hyper-threading or multicore processors, mean that parallel computing resources are available for inexpensive desktop computers. In only a few years, many standard software products will be based on concepts of parallel programming implemented on such hardware, and the range of applications will be much broader than that of scientific computing, up to now the main application area for parallel computing. Rauber and Rünger take up these recent developments in processor architecture by giving detailed descriptions of parallel programming techniques that are necessary for developing efficient programs for multicore processors as well as for parallel cluster systems and supercomputers. Their book is structured in three main parts, covering all areas of parallel computing: the architecture of parallel systems, parallel programming models and environments, and the implementation of efficient application algorithms. The emphasis lies on parallel programming techniques needed for different architectures. The main goal of the book is to present parallel programming techniques that can be used in many situations for many application areas and which enable the reader to develop correct and efficient parallel programs. Many examples and exercises are provided to show how to apply the techniques. The book can be used as both a textbook for students and a reference book for professionals. The presented material has been used for courses in parallel programming at different universities for many years.

Download or read book Parallel Scientific Computing in C and MPI written by George Em Karniadakis and published by Cambridge University Press. This book was released on 2003-06-16 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerical algorithms, modern programming techniques, and parallel computing are often taught serially across different courses and different textbooks. The need to integrate concepts and tools usually comes only in employment or in research - after the courses are concluded - forcing the student to synthesise what is perceived to be three independent subfields into one. This book provides a seamless approach to stimulate the student simultaneously through the eyes of multiple disciplines, leading to enhanced understanding of scientific computing as a whole. The book includes both basic as well as advanced topics and places equal emphasis on the discretization of partial differential equations and on solvers. Some of the advanced topics include wavelets, high-order methods, non-symmetric systems, and parallelization of sparse systems. The material covered is suited to students from engineering, computer science, physics and mathematics.

Book excerpt: R is a wonderful thing, indeed: in recent years this free, open-source product has become a popular toolkit for statistical analysis and programming. Two of R's limitations -- that it is single-threaded and memory-bound -- become especially troublesome in the current era of large-scale data analysis. It's possible to break past these boundaries by putting R on the parallel path. Parallel R will describe how to give R parallel muscle. Coverage will include stalwarts such as snow and multicore, and also newer techniques such as Hadoop and Amazon's cloud computing platform.

Download or read book Parallel Perspectives written by Holly Gordon and published by City Point Press. This book was released on 2020-10-06 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: The eye-arresting images in this original contemporary art book feature two popular mediums, painting and photography. Although the art is inspired by the Long Island landscape, its visual appeal in artists’ interpretations of locations is universal. Paired with the dialog of the artists, the narrative becomes an intimate conversation with the reader. Combining life, loss, serendipity and art, it portrays two artists, whose conceptually similar work evolved independently until social media brought them together. Their collaboration continues to produce treasures of stunning, memorable beauty. The improbable pairing of Holly Gordon, photographer from Bay Shore, Long Island, and Ward Hooper, painter from Northport, Long Island, is a symbiotic match. Their artistic relationship is an affirmation of the human spirit in an age where most can’t seem to detach from objects. These two contemporary artists discovered a serendipitous connection to the earlier American artistic and personal alliance of Arthur Dove and Helen Torr, whose work was inspired by the same Long Island locations. The past thus joined the present, deepening Gordon and Hooper’s bond, both personally and geographically. In Gordon and Hooper’s intimate relationship there is a sense of empathy, connection, and mutual discovery that is invincible. Ward Hooper and Holly Gordon understand that the meaning of their journey extends beyond themselves. Their camaraderie and brilliant exposition beckons others to do the same and thereby reach their own heights in art and life. The transformative journey that unfolds centers on art as a positive force that ultimately unites two creative spirits. I found the imagery captivating and the text inspirational. Learning about how these two people from different art disciplines came together to help heal and enrich each others’ lives (and create wonderful imagery throughout the process) made me appreciate my life and relationships even more. The book may even encourage you to create something new, or collaborate with someone you already know...or someone who is out there waiting to be a part of your “Light's Journey.” -- Andrew Darlow, Photographer, Educator and Author ......A love story of friendship and renewal. Holly and Ward were meant to meet to discover their connection through art and nature. Two wonderful artists exploring life together through the warmth of colors, brush and lens strokes and subjects they created separately at different times and then together revealing their deep passion for life, friendship and art. --Charlee M. Miller, Executive Director, Art League of Long Island, Dix Hills, N.Y. Parallel Perspectives: The Brush/Lens Project gives us seamlessly created images that work on many levels: They pay attention to tiny details yet pulse with large swaths of vibrant color. They look like paintings — but they could be photographs, and vice versa. These are eye-arresting scenes, a visual harvest of the natural beauty that surrounds us, creating lasting sights that celebrate what talented artists have always quested for: the light. Holly Gordon finds images and builds digital layers that blend an unflinching assessment by a documentary photographer and environmentalist with a painterly sensitivity; Ward Hooper’s loose brushstrokes capture the ever-shifting light and shadow through watercolors that are as elusive as the light. Their collaboration continues to produce treasures of stunning, memorable beauty.—Annie Wilkinson Blachley’s features and cover stories have been published by The New York Times, Los Angeles Times, and national and regional newspapers and magazines. She is a copy editor and columnist for the Long Island Press and writes several monthly columns for Long Island Woman Magazine
