Chemical Searching on an Array Processor: No. 2 (Computers & Chemical Structure Information S.) - Hardcover
Synopsis
Reports on a research project undertaken in the Department of Information Studies at the University of Sheffield, into the processing of chemical structures by a parallel process know as a distributed array processor. Begins by reviewing the current understanding of chemical structure processing, the underlying graph theory, the nature of algorithms, and the hardware and software of parallel computing systems. Then describes in detail the development and testing of a variety of algorithms to match device characteristics. Double spaced with wide margins. Annotation copyright Book News, Inc. Portland, Or.

Synopsis
One of the aspects of research and development in science and technology is seen when newly developed informatics technologies are applied to an area where such advances are clearly needed. One such example is the application of supercomputers to molecular dynamics. Another is the use of advanced graphics displays for the visulaization of molecular, and biomolecular, structure. This book describes another such example: the application of parallel processing hardware to retrieval from databases of chemical structure information. It is no mere coincidence that the examples quoted, including the present one, relate to the chemical domain. The application of informatics to chemistry has been particularly frutiful, and builds upon the well-developed information systems which have served chemistry, and related sciences, for more than a century.
The readiness with which chemical knowledge may be systematized and formalized, by means of nomenclatures, notations and formulae has provided an opportunity, unique among the sciences, for the application of systems and techniques of documentation and informatics In particular, it is the ubiquitousness of the chemical structure diagram representation, a complete and unambiguous description of a substance, which may be both represented by computer graphics, and stored and retrieved according to the formalisms of graph theory, which underlies the sophisticated computer-based chemical information systems developed over the past decades. It is this unifying factor which forms the common link between the books of this series. The handling of chemical information, on this basis, has provided a test-bed for many experimental and newly developed informatics systems, both hardware and software. The chemical inforamtion environment provides both a test for the new systems themselves, in an environment often somewhat removed from their designers' original conceptions, and also the potential of novel and valuable capabilities for chemists and chemical inforamtion specialists.In particular, advances made in chemical intimidation systems have often been transferred at a later stage to more general information processing situations. This book describes the application of a novel type of computer hardware, a Distributed Array Processor, providing a parallel processing capability, to chemical structure information. Parallel processing hardware, universally hailed as one of the fundamental components of future information processing systems, made slower headway than expected in the database retrieval context. Terence Wilson's studies, reported here, give a unique insight, not merely in to the the theoretical and practical issues involved in the use of this kind of computer system for information retrieval. The value of this book goes beyond its exposition of the advantages, and associated of parallel hardware of this type in chemical information systems, valuable though these detailed and thorough analyses and experiments are. They also throw a more general light on the applicability of these systems for data processing in the wider context."About this title" may belong to another edition of this title.
