    Scientific Programming and Computer Architecture

    A variety of programming models relevant to scientists explained, with an emphasis on how programming constructs map to parts of the computer.What makes computer programs fast or slow? To answer this question, we have to get behind the abstractions of programming languages and look at how a computer really works. This book examines and explains a variety of scientific programming models (programming models relevant to scientists) with an emphasis on how programming constructs map to different parts of the computer's architecture. Two themes emerge: program speed and program modularity. Throughout this book, the premise is to "get under the hood," and the discussion is tied to specific programs. The book digs into linkers, compilers, operating systems, and computer architecture to understand how the different parts of the computer interact with programs. It begins with a review of C/C++ and explanations of how libraries, linkers, and Makefiles work. Programming models covered include Pthreads, OpenMP, MPI, TCP/IP, and CUDA.The emphasis on how computers work leads the reader into computer architecture and occasionally into the operating system kernel. The operating system studied is Linux, the preferred platform for scientific computing. Linux is also open source, which allows users to peer into its inner workings. A brief appendix provides a useful table of machines used to time programs. The book's website (https://github.com/divakarvi/bk-spca) has all the programs described in the book as well as a link to the html text

    Performance analysis for wireless G (IEEE 802.11G) and wireless N (IEEE 802.11N) in outdoor environment

    Get PDF
    This paper described an analysis the different capabilities and limitation of both IEEE technologies that has been utilized for data transmission directed to mobile device. In this work, we have compared an IEEE 802.11/g/n outdoor environment to know what technology is better. The comparison consider on coverage area (mobility), throughput and measuring the interferences. The work presented here is to help the researchers to select the best technology depending of their deploying case, and investigate the best variant for outdoor. The tool used is Iperf software which is to measure the data transmission performance of IEEE 802.11n and IEEE 802.11g

    A resource-based view of the firm : integrating the role of IT as a strategic resource - an empirical study of South African personal financial services (Assurance) firms, 1999-2003

    Includes bibliographical references (p. 502-531).This research explores an "inside the black box" view on how IT enables sustainable competitive advantage. Most researchers have investigated IT competitive competencies that make up a firm's strategic framework to understand competitive advantage. However, Resource-Based Theory (RBT) probes into the inner workings of a firm, suggesting that a firm's IT assets and resources are the basis of a firm's "rare" core competencies to compete successfully. Using RBT and research in the economics, strategy, and IT literatures, an initial "Framework of Sustainability" was created, against which the case studies were conducted. This framework was used as foundation to develop semi-structured questionnaires in which 45, 90 minute (on average) interviews were conducted with managers in the four firms. Both internal and external documents about the firms and the industry were used as sources of corroborating evidence. In addition, a "bottoms up" view was obtained with evidence gathered from a short questionnaire and focus groups discussions held with 178 staff employees in the four firms
