Contemporary distributed file systems are monolithic and only support single file abstractions. Nowadays, as Sai-Lai Lo explains, network storage devices have to accommodate new information media such as digital audio and video, with data radically different from the traditional text and binary code that contemporary file systems are optimized for. In this book, the author shows how, by combining new and traditional media, information can be recorded and presented in the most suitable way, and the value of a piece of information can be further enhanced by linking together related pieces. However, composite data and cross-reference between data items raise a number of system issues that have not been addressed properly before. Lo defines a new multiservice storage architecture that meets the needs of existing and emerging applications and can support multiple file abstractions. He also explores a number of related design issues. Researchers in the areas of distributed systems, network multimedia and network storage services will enjoy this book.
This unique text/reference describes an exciting and novel approach to supercomputing in the DataFlow paradigm. The major advantages and applications of this approach are clearly described, and a detailed explanation of the programming model is provided using simple yet effective examples. The work is developed from a series of lecture courses taught by the authors in more than 40 universities across more than 20 countries, and from research carried out by Maxeler Technologies, Inc. Topics and features: presents a thorough introduction to DataFlow supercomputing for big data problems; reviews the latest research on the DataFlow architecture and its applications; introduces a new method for the rapid handling of real-world challenges involving large datasets; provides a case study on the use of the new approach to accelerate the Cooley-Tukey algorithm on a DataFlow machine; includes a step-by-step guide to the web-based integrated development environment WebIDE.
The transportation and storage of fresh fruits and vegetables is an international operation where technology must be used to ensure that produce reaches the consumer in the best possible condition. The use of controlled atmosphere storage has great potential to reduce the postharvest use of chemicals, maintain nutritional quality and organoleptic characteristics and reduce physical losses.
