Book Description
Dealing with system problems—from user login failures to server crashes--is a critical part of a system administrator's job. A down system can cost a business thousands of dollars per minute. But there is little or no information available on how to troubleshoot and correct system problems; in most cases, these skills are learned in an ad-hoc manner, usually in the pressure-cooker environment of a crisis. This is the first book to address this lack of information.The authors (both experienced Tru64 UNIX support engineer for Compaq) systematically present the techniques and tools needed to find and fix system problems. The first part of the book presents the general principles and techniques needed in system troubleshooting. These principles and techniques are useful not only for UNIX system administrators, but for anyone who needs to find and fix system problems. After this foundation, the authors describe troubleshooting tools used in the UNIX environment. The remainder of the book covers specific areas of the Tru64 UNIX operating system in detail: listing common problems, their causes, how to detect them, and how to correct them. Each chapter includes a "Before You Call Support" section that details the most important things to check and correct before it's necessary to call Compaq technical support. The authors also include decision trees to help the reader systematically isolate particular problem types.· "Before You Call Tech Support" sections·Tables and diagrams for quick access to precise data·Decision trees to help choose the best way to troubleshoot a particular problem

Book Description
Understanding ASPs: The new Internet business.Application Service Providers (ASPs) appeal to small businesses by offering a wide variety of web-hosted software programs including e-commerce, communications, project management, financial, word processing and human resourse applications. ASPs offer inexpensive use of software and the ability to share access among people in different locations. There is a huge buzz in the computing industry about ASPs and many ISPs (Internet Service Providers) are gearing up to become ASPs. These companies are in need of a guide - this is the first book to focus on how a company can become an ASP.ASP Configuration Handbook: A Guide for ISPs covers all the business issues surrounding the transformation of an Internet Service Provider to an Application Service Provider, as well as the technical issues associated with offering applications to customers.

Book Description
The first book to describe how Microsoft's Component Object Model (COM) can be supported on computer systems other than Windows. Drawing on Compaq's groundbreaking work of porting COM/DCOM to its OpenVMS and Tru64 UNIX Alpha platforms, COM Beyond Microsoft explains how the COM standard can help enterprises integrate their applications across a heterogeneous computing environment. This book details the innovative COM support now native on Tru64 UNIX and OpenVMS and reveals how developers can exploit COM on OpenVMS and COM on Tru64 UNIX to create portable software components that run virtually unchanged on OpenVMS, Tru64 UNIX, Windows NT, Windows 2000, and other major computing platforms. COM Beyond Microsoft highlights the business and technical benefits of implementing distributed and portable COM applications, especially versus other strategies and technologies such as CORBA and Java. The book explains the APIs, utilities, libraries and run-time environments developers must understand to create COM applications for OpenVMS and Tru64 UNIX. It also contains implementation and configuration techniques for running COM programs on Tru64 UNIX and OpenVMS. COM Beyond Microsoft uniquely explains a controversial topic of major interest to organizations and developers in an enterprise computing context. First book on a controversial topic critically important to many large organizations Authors are among few in industry with relevant experience

Book Description
A step-by-step guide to parallelizing cem codes The future of computational electromagnetics is changing drastically as the new generation of computer chips evolves from single-core to multi-core. The burden now falls on software programmers to revamp existing codes and add new functionality to enable computational codes to run efficiently on this new generation of multi-core CPUs. In this book, you'll learn everything you need to know to deal with multi-core advances in chip design by employing highly efficient parallel electromagnetic code. Focusing only on the Method of Moments (MoM), the book covers: In-Core and Out-of-Core LU Factorization for Solving a Matrix Equation A Parallel MoM Code Using RWG Basis Functions and ScaLAPACK-Based In-Core and Out-of-Core Solvers A Parallel MoM Code Using Higher-Order Basis Functions and ScaLAPACK-Based In-Core and Out-of-Core Solvers Turning the Performance of a Parallel Integral Equation Solver Refinement of the Solution Using the Conjugate Gradient Method A Parallel MoM Code Using Higher-Order Basis Functions and Plapack-Based In-Core and Out-of-Core Solvers Applications of the Parallel Frequency Domain Integral Equation Solver Appendices are provided with detailed information on the various computer platforms used for computation; a demo shows you how to compile ScaLAPACK and PLAPACK on the Windows® operating system; and a demo parallel source code is available to solve the 2D electromagnetic scattering problems. Parallel Solution of Integral Equation-Based EM Problems in the Frequency Domain is indispensable reading for computational code designers, computational electromagnetics researchers, graduate students, and anyone working with CEM software.
