Supercomputing

The Grid is an emerging infrastructure that will fundamentally change the way we think about-and use-computing. The word Grid is used by analogy with the electric power grid, which provides pervasive access to electricity and has had a dramatic impact on human capabilities and society. Many believe that by allowing all components of our information technology infrastructure-computational capabilities, databases, sensors, and people-to be shared flexibly as true collaborative tools the Grid will have a similar transforming effect, allowing new classes of applications to emerge.

CMS

An open-source content management system (CMS) like Drupal can be a great resource for anyone who would like to develop and maintain a website. In the past, in order to make a website, you had to manually assemble all the files and develop a fair amount of technical expertise; however, a CMS can automate and significantly simplify many parts of the process. Adding content to a site is easy with Drupal, including text and pictures. The book walks you through the process with step-by-step examples. Features Explores everything needed to help beginners start creating and maintaining a website with the latest version of Drupal. Provides complete coverage of all the essential features of Drupal 7. Helps you develop technical and critical skills to navigate the fast-moving world of CMS. A content management system (CMS) can automate and simplify many website tasks. It can make it easier to create and maintain a site, as an alternative to manually creating one. There are a variety of CMS systems, and Drupal is one of the best. The book is designed for beginners, so you don't necessarily need to know anything about code or websites; it's an opportunity to explore what it's like to create a website. Using a CMS like Drupal requires a hosting account, and the book shows how "quick install" tools help make it easier to install Drupal software. As with any kind of software, there are updates and important security issues; the book discusses what you need to do, in easy-to-understand language. One of the great strengths about CMS systems like Drupal is the flexibility you have to change things around as you like on your site. It used to be that when you wanted to make any changes to your site, you'd need to painstakingly change the code on every page; now, you can use an interface to drag and drop various features into place on your website's page. CMS systems like Drupal make it a lot easier to try a new look and feel for your site, using "Themes." You can download and enable new themes, and customize them, to get your site looking how you like. The book discusses the options and limitations of CMS systems, and also talks about the question: at what point would you need to work with a designer There are a variety of modules and wizards that you can use to add new features to your site. An example is a free tool from Google that allows you to create a panel with automated news. You can choose what type of news to have Google look for, and the latest items are automatically displayed on your site as they become available. It's a nice way to have fresh content. Later chapters talk about promoting your website on social media, such as making a post on Facebook that introduces your site to your friends. Readers are also introduced to making a Facebook page, which can be a nice complement to your own website. One way to connect social media to your website is to make a Facebook page, and then make posts on it, to tell people who like your page about your website, and to update them with articles that you've added to your site. One of the things you might like to try when making your website is to promote it on Facebook with a Facebook ad. They're easy to create, and fun. The book has an introduction to "social advertising," including Facebook and Google ads. From the Introduction What You'll Find in This Book This book contains an easy-to-understand introduction to related concepts, and a series of step-by-step examples that can help you learn how to use Drupal to create and maintain a website. The coverage includes using a "quick-install" Web hosting account, which can greatly reduce the complexity of installing Drupal. (Drupal software is free, but you need a monthly Internet hosting account to run it.) Who This Book Is For You'll find that this book is written with beginners in mind; no prior expertise is required, except some familiarity with how to browse the Internet and use a PC. For example, in order to help build confidence and experience, an early chapter introduces readers to Google Sites (a basic alternative to Drupal), which is entirely free and can be a good place to start learning about content management systems. Like any software, Drupal is not perfect, and its limitations are discussed openly, with suggestions especially suited for beginners on how to overcome them. How This Book Is Organized The first part of the book introduces the reader to content management systems, including taking a look at Google Sites, to help build confidence. This section also provides an introduction to opensourcecms.com, where you can try a live demo of an open source CMS, and takes a look at a live Drupal site, to provide further exposure to CMS concepts. The second part is focused on starting an account, installing Drupal with a timesaving "one-click" installation tool, and covering important basics such as security and basic configuration. Then the reader is introduced to adding content to the site, which includes learning about various modules that can add additional features and functions. The third part introduces some techniques and concepts for promoting a site once it is created, using social networks and social advertising.

Cloud computing

Continuing to stretch the boundaries of computing and the types of problems computers can solve, high performance, cloud, grid computing have emerged to address increasingly advanced issues by combining resources. Cloud, Grid and High Performance Computing: Emerging Applications offers new and established perspectives on architectures, services and the resulting impact of emerging computing technologies. Intended for professionals and researchers, this publication furthers investigation of practical and theoretical issues in the related fields of grid, cloud, and high performance computing.

High Performance Computing

This book is a "must" for anyone who needs to worry about computer performance, either as a software developer or as a buyer. But it also provides valuable insights for those among us who do relatively little programming and run mostly third-party application software. Even if you never touch a line of code, High Performance Computing will give you a feel for how the most recent generation of computer hardware works. If you work with computers, you owe it to yourself to understand the new directions that workstation architecture has taken in the last half decade, including RISC-based workstation architectures like DEC Alpha/AXP, the IBM RS/6000 and the HP 9000/700 series.This book covers everything, from the basics of modern workstation architecture, to structuring benchmarks, to squeezing more performance out of critical applications. It also explains how optimizing compilers work: it discusses what a good compiler can do for you and, more important, what you have to do yourself. The author also discusses techniques for improving memory access patterns and taking advantage of parallelism. The book closes with a look at the high-performance future: parallel computers, including exotic distributed memory multiprocessors, and the more "garden-variety" shared memory processors that are already appearing on people's desktops.High Performance Computing pays special attention to memory issues; perhaps the most important story in high performance computing (and one you're not likely to be told by vendors) is the increasing disparity between CPU speeds and memory speeds.Another valuable section of the book discusses the benchmarking process: how to evaluate a computer's performance. Kevin Dowd discusses several of the "standard" industry benchmarks, explaining what they measure and what they don't. He also explains how to set up your own benchmark: how to structure the code, how to measure the results, and how to interpret them.

programación

Este libro se ha diseñado para que sea todo lo comprensible y accesible que es posible teniendo en cuenta que es un libro de Java. En él va a encontrar tanto Java como quepa en sus páginas. Java no es un lenguaje de programación ordinario: inspira devoción, pasión, exaltación y excentricidad (no se menciona exasperación ni frustración). Esperemos que lo que Java tiene que ofrecer le resulte irresistible al igual que ha ocurrido con otros muchos programadores (de hecho, la programación en Java es uno de los conocimientos más lucrativos que se pueden tener hoy en día).

Acerca de este libro Este libro se desarrolló conforme enseñaba MATLAB y otros lenguajes de computación a es-tudiantes nuevos de ingeniería en la Salt Lake community College. Me sentía frustrada por la falta de un texto que "comenzara desde el principio”. Aunque había muchos libros de referencia muy abarcadores, todos suponían un nivel elevado de matemáticas y conocimientos de computación que mis estudiantes no tenían. Además, debido a que MATLAB fue adoptado en sus orígenes por profesionales de los campos de procesamiento de señales e ingeniería eléctrica, la mayoría de dichos textos daban ejemplos principalmente de dichas áreas, enfoque que no se adaptaba a un currículo general de ingeniería. Este texto comienza con álgebra básica y muestra cómo se puede usar MATLAB para resolver problemas de ingeniería de un rango amplio de disciplinas. Los ejemplos proceden de conceptos que se introducen en las primeras clases de química y física, y de las clases de ingeniería de los primeros semestres. Se utiliza de manera consistente una metodología estándar para resolver problemas.
