IEEE Standard for Scalable Coherent Interface (SCI)


Book Description

Abstract: The scalable coherent interface (SCI) provides computer-bus-like services but, instead of a bus, uses a collection of fast point-to-point unidirectional links to provide the far higher throughput needed for high-performance multiprocessor systems. SCI supports distributed, shared memory with optional cache coherence for tightly coupled systems, and message-passing for loosely coupled systems. Initial SCI links are defined at 1 Gbyte/s (16-bit parallel) and 1 Gb/s (serial). For applications requiring modular packaging, an interchangeable module is specified along with connector and power. The packets and protocols that implement transactions are defined and their formal specification is provided in the form of computer programs. In addition to the usual read-and-write transactions, SCI supports efficient multiprocessor lock transactions. The distributed cache-coherence protocols are efficient and can recover from an arbitrary number of transmission failures. SCI protocols ensure forward progress despite multiprocessor conflicts (no deadlocks or starvation). Keywords: bus architecture, bus standard, cache coherence, distributed memory, fiber optic, interconnect, I/O system, link, mesh, multiprocessor, network, packet protocol, ring, seamless distributed computer, shared memory, switch, transaction set.

On-line Monitoring Systems and Computer Tool Interoperability


Book Description

Ludwig (Institut fur Informatik, Ruprecht-Karls-Universitat Heidelberg, Germany) and Miller (computer science, U. of Wisconsin, US) present five papers examining the construction and methodology of tools for debugging and performance analysis in parallel programs. After a review of the past decade's work in debuggers and performance analyzers, papers look a tool infrastructure, an operational tool environment for multi-thread and multi-process debugging and execution visualization, multi-execution performance tuning, and the specification of performance properties of parallel applications using compound events.

Information Engineering and Applications


Book Description

In past twenty years or so, information technology has influenced and changed every aspect of our lives and our cultures. Without various IT-based applications, we would find it difficult to keep information stored securely, to process information and business efficiently, and to communicate information conveniently. In the future world, ITs and information engineering will play a very important role in convergence of computing, communication, business and all other computational sciences and application and it also will influence the future world's various areas, including science, engineering, industry, business, law, politics, culture and medicine. The International Conference on Information Engineering and Applications (IEA) 2011 is intended to foster the dissemination of state-of-the-art research in information and business areas, including their models, services, and novel applications associated with their utilization. International Conference on Information Engineering and Applications (IEA) 2011 is organized by Chongqing Normal University, Chongqing University, Shanghai Jiao Tong University, Nanyang Technological University, University of Michigan and the Chongqing University of Arts and Sciences, and is sponsored by National Natural Science Foundation of China (NSFC). The objective of IEA 2011 is to will provide a forum for engineers and scientists in academia, industry, and government to address the most innovative research and development . Information Engineering and Applications provides a summary of this conference including contributions for key speakers on subjects such as technical challenges, social and economic issues, and ideas, results and current work on all aspects of advanced information and business intelligence.




Advances in High Performance Computing


Book Description

Most of the papers in this volume were presented at the NATO Advanced Research Workshop High Performance Computing: Technology and Application, held in Cetraro, Italy from 24 to 26 of June, 1996. The main purpose of the Workshop was to discuss some key scientific and technological developments in high performance computing, identify significant trends and defme desirable research objectives. The volume structure corresponds, in general, to the outline of the workshop technical agenda: general concepts and emerging systems, software technology, algorithms and applications. One of the Workshop innovations was an effort to extend slightly the scope of the meeting from scientific/engineering computing to enterprise-wide computing. The papers on performance and scalability of database servers, and Oracle DBMS reflect this attempt We hope that after reading this collection of papers the readers will have a good idea about some important research and technological issues in high performance computing. We wish to give our thanks to the NATO Scientific and Environmental Affairs Division for being the principal sponsor for the Workshop. Also we are pleased to acknowledge other institutions and companies that supported the Workshop: European Union: European Commission DGIII-Industry, CNR: National Research Council of Italy, University of Calabria, Alenia Spazio, Centro Italiano Ricerche Aerospaziali, ENEA: Italian National Agency for New Technology, Energy and the Environment, Fujitsu, Hewlett Packard-Convex, Hitachi, NEC, Oracle, and Silicon Graphics-Cray Research.

Towards Teracomputing - Proceedings Of The Eighth Ecmwf Workshop On The Use Of Parallel Processors In Meteorology


Book Description

The demand for more and more computer power in numerical weather prediction and meteorological research is as strong as ever. Previously, the world meteorological community tried to meet this demand by exploiting parallelism. In this field, the European Centre for Medium-Range Weather Forecasts has established itself as the central venue for bringing together operational weather forecasters, climate researchers and parallel computer manufacturers to share their experiences through a series of workshops held every other year. This book reports on the latest such workshop. It gives an excellent overview of the latest achievements in this field. The demand for and the developments towards Teracomputing, the next order of magnitude in meteorological supercomputing, are given particular attention.
