Available in PDF, EPUB and Kindle. Book excerpt: Supercomputers play a significant and growing role in a variety of areas important to the nation. They are used to address challenging science and technology problems. In recent years, however, progress in supercomputing in the United States has slowed. The development of the Earth Simulator supercomputer by Japan that the United States could lose its competitive advantage and, more importantly, the national competence needed to achieve national goals. In the wake of this development, the Department of Energy asked the NRC to assess the state of U.S. supercomputing capabilities and relevant R&D. Subsequently, the Senate directed DOE in S. Rpt. 107-220 to ask the NRC to evaluate the Advanced Simulation and Computing program of the National Nuclear Security Administration at DOE in light of the development of the Earth Simulator. This report provides an assessment of the current status of supercomputing in the United States including a review of current demand and technology, infrastructure and institutions, and international activities. The report also presents a number of recommendations to enable the United States to meet current and future needs for capability supercomputers.

Download or read book A Scientist's and Engineer's Guide to Workstations and Supercomputers written by Rubin H. Landau and published by Wiley-Interscience. This book was released on 1992-12-25 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: A scientist’s and engineer’s guide to Workstations and Supercomputers Crack the Unix code and put its power to work for you. If you’re seeking such clear-cut guidance, your search will end with the first Unix survival manual designed specifically for practicing scientists and engineers like you. Avoiding the narrower concerns and complicated jargon of computer science, this guide shows you how to master the complexities of accomplishing computer projects—from start to finish—predominantly under a Unix operating system. With the help of clarifying examples and tutorials, you’ll learn how to write and organize files and programs as well as run, debug, and visualize the results of scientific programs on workstations and supercomputers. At the same time, you’ll discover how to complete these projects while working on other systems and on other versions of Unix. This user-friendly guide offers you the basics on Unix commands and on setting up and using workstations, and goes on to simplify the once-daunting tasks of transferring files between workstations and adjusting X Windows. You’ll also gain a solid grasp of more advanced Unix tools, such as its sophisticated editing, filing, and debugging capabilities, and of programming computers with differing architectures. Complete with accompanying computer disk packed with practice programs and data files, this book will increase your creativity, productivity, and effectiveness on the job by demonstrating how you can quickly learn to wield one of your most formidable tools—the Unix system. Covers all major versions of Unix and systems from major hardware vendors, including: System V, BSD, IBM’s AIX, SUNOS, HP-UX, Unicos.

Download or read book Supercomputers in Theoretical and Experimental Science written by Jozef T. Devreese and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The International Workshop on "The Use of Super computers in Theoretical Science" took place from July 30 till August 1, 1984, at the Conference Center of the "Priorij Corsendonk", close to the city of Antwerpen, Belgium. During the past decade computational science has developed itself to a third methodology besides the experimental and theoretical sciences. This remarkable evolution was only possible due to a drastic increase of the computational power of present day computers. Indeed, computational physics and chemistry as such is certainly not new, but it was only during the past ten years or so that realistic problems could be solved numerically to a sufficient degree of accuracy. During this workshop the state-of-the-art in high speed computation was presented by a team of lecturers who are well known for their competence in this field. It is a pleasure to thank several organizations and companies who made this workshop possible. First of all, the main sponsors: the Belgian National Science Found ation (NFWO-FNRS) and the "Universitaire Instelling Ant werpen". Next, the co-sponsors: Agfa-Gevaert N. V., Control Data Belgium and the Belgian Ministry of Education. Special thanks are due to Dr. P.E. Van Camp and Drs. H. Nachtegaele for the practical organization of this workshop. I would also like to thank Mrs. H. Evans for typing the manuscripts and for preparing the author and subject index. v Last but not least I express my gratitude to Mr.

Download or read book Supercomputers and Their Performance in Computational Fluid Dynamics written by Kozo Fujii and published by Springer Science & Business Media. This book was released on 2013-03-08 with total page 209 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercomputer technologies have evolved rapidly since the first commercial-based supercomputer, CRAY-1 was introduced in 1976. In early 1980's three Japanese super computers appeared, and Cray Research delivered the X-MP series. These machines including the later-announced CRAY-2 and NEC SX series created one generation of supercomputers, and the market was spread dramatically. The peak performance was higher than 1 GFLOPS and the compiler improvement was remarkable. There appeared many articles and books that described their architecture and their performance on The late 1980's saw a new generation of supercomputers. several benchmark problems. Following CRAY Y-MP and Hitachi S-820 delivered in 1988, NEC announced SX-3 and Fujitsu announced the VP2000 series in 1990. In addition, Cray Research announced the Y-MP C-90 late in 1991. The peak performance of these machines reached several to a few ten's GFLOPS. The hardware characteristics of these machines are known, but their practical performance has not been well documented so far. Computational Fluid Dynamics (CFD) is one of the important research fields that have been progressing with the growth of supercomputers. Today's fluid dynamic re search cannot be discussed without supercomputers and since CFD is one of the im portant users of supercomputers, future development of supercomputers has to take the requirements of CFD into account. There are many benchmark reports available today. However, they mostly use so called kernels. For fluid dynamics researchers, benchmark test on real fluid dynamic codes are necessary.
