Número de Páginas: 463

Innovations in hardware architecture, like hyper-threading or multicore processors, mean that parallel computing resources are available for inexpensive desktop computers. In only a few years, many standard software products will be based on concepts of parallel programming implemented on such hardware, and the range of applications will be much broader than that of scientific computing, up to now the main application area for parallel computing. Rauber and Rünger take up these recent developments in processor architecture by giving detailed descriptions of parallel programming techniques that are necessary for developing efficient programs for multicore processors as well as for parallel cluster systems and supercomputers. Their book is structured in three main parts, covering all areas of parallel computing: the architecture of parallel systems, parallel programming models and environments, and the implementation of efficient application algorithms. The emphasis lies on parallel programming techniques needed for different architectures.

Structured Parallel Programming

Autor: Michael Mccool , James Reinders , Arch Robison

Número de Páginas: 434

Programming is now parallel programming. Much as structured programming revolutionized traditional serial programming decades ago, a new kind of structured programming, based on patterns, is relevant to parallel programming today. Parallel computing experts and industry insiders Michael McCool, Arch Robison, and James Reinders describe how to design and implement maintainable and efficient parallel algorithms using a pattern-based approach. They present both theory and practice, and give detailed concrete examples using multiple programming models. Examples are primarily given using two of the most popular and cutting edge programming models for parallel programming: Threading Building Blocks, and Cilk Plus. These architecture-independent models enable easy integration into existing applications, preserve investments in existing code, and speed the development of parallel applications. Examples from realistic contexts illustrate patterns and themes in parallel algorithm design that are widely applicable regardless of implementation technology. The patterns-based approach offers structure and insight that developers can apply to a variety of parallel programming models Develops a...

Parallel Programming and Compilers

Autor: Constantine D. Polychronopoulos

Número de Páginas: 253

The second half of the 1970s was marked with impressive advances in array/vector architectures and vectorization techniques and compilers. This progress continued with a particular focus on vector machines until the middle of the 1980s. The major ity of supercomputers during this period were register-to-register (Cray 1) or memory-to-memory (CDC Cyber 205) vector (pipelined) machines. However, the increasing demand for higher computational rates lead naturally to parallel comput ers and software. Through the replication of autonomous processors in a coordinated system, one can skip over performance barriers due technology limitations. In princi ple, parallelism offers unlimited performance potential. Nevertheless, it is very difficult to realize this performance potential in practice. So far, we have seen only the tip of the iceberg called "parallel machines and parallel programming". Parallel programming in particular is a rapidly evolving art and, at present, highly empirical. In this book we discuss several aspects of parallel programming and parallelizing compilers. Instead of trying to develop parallel programming methodologies and paradigms, we often focus on more advanced...

Parallel Programming Using C++

Autor: Gregory V. Wilson , Paul Lu

Número de Páginas: 796

Foreword by Bjarne Stroustrup Software is generally acknowledged to be the single greatest obstacle preventing mainstream adoption of massively-parallel computing. While sequential applications are routinely ported to platforms ranging from PCs to mainframes, most parallel programs only ever run on one type of machine. One reason for this is that most parallel programming systems have failed to insulate their users from the architectures of the machines on which they have run. Those that have been platform-independent have usually also had poor performance. Many researchers now believe that object-oriented languages may offer a solution. By hiding the architecture-specific constructs required for high performance inside platform-independent abstractions, parallel object-oriented programming systems may be able to combine the speed of massively-parallel computing with the comfort of sequential programming. Parallel Programming Using C++ describes fifteen parallel programming systems based on C++, the most popular object-oriented language of today. These systems cover the whole spectrum of parallel programming paradigms, from data parallelism through dataflow and distributed shared...

Parallel Programming with Co-arrays

Autor: Robert W. Numrich

Número de Páginas: 157

Parallel Programming with Co-Arrays describes the basic techniques used to design parallel algorithms for high-performance, scientific computing. It is intended for upper-level undergraduate students and graduate students who need to develop parallel codes with little or no previous introduction to parallel computing. It is also intended as a reference manual for researchers active in the field of scientific computing. All the algorithms in the book are based on partition operators. These operators provide a unifying principle that fits seemingly disparate techniques into an overall framework for algorithm design. The book uses the co-array programming model to illustrate how to write code for concrete examples, but it emphasizes that the important concepts for algorithm design are independent of the programming model. With these concepts in mind, the reader can write algorithms in different programming models based on personal taste and comfort.

From cloud computing to smartphones, today's highest-growth software environments depend on parallel programming. That's why parallel programming is increasingly viewed as a foundational job skill expected of every professional developer. However, parallel computing requires traditional application developers to think and work differently; that's why it's so often viewed as difficult. In Parallel Programming Patterns, three leading experts cut through the complexity, showing how to "think parallel," and offering practical solutions to many of the challenges you'll encounter. Drawing on immense experience programming parallel systems and teaching others to do so, the authors cover all this, and more: What you need to know about concurrency in parallel programs, parallel architecture, and the jargon of parallel computing How to find concurrency and decompose tasks and data How to select and work with algorithm and supporting structures How to work with implementation mechanisms for UE management, synchronization, and communication Getting started with OpenMP, MPI, and concurrent programming in Java

Parallel Processing and Parallel Algorithms

Autor: Seyed H Roosta

Número de Páginas: 590

Motivation It is now possible to build powerful single-processor and multiprocessor systems and use them efficiently for data processing, which has seen an explosive ex pansion in many areas of computer science and engineering. One approach to meeting the performance requirements of the applications has been to utilize the most powerful single-processor system that is available. When such a system does not provide the performance requirements, pipelined and parallel process ing structures can be employed. The concept of parallel processing is a depar ture from sequential processing. In sequential computation one processor is in volved and performs one operation at a time. On the other hand, in parallel computation several processors cooperate to solve a problem, which reduces computing time because several operations can be carried out simultaneously. Using several processors that work together on a given computation illustrates a new paradigm in computer problem solving which is completely different from sequential processing. From the practical point of view, this provides sufficient justification to investigate the concept of parallel processing and related issues, such as...

En la naturaleza se presentan infinidad de problemas susceptibles de estudio. La complejidad de un gran número de estos problemas es tan alta que se deben recurrir a modelos físicos, matemáticos, computacionales, etc. para poder tratar y estudiar los efectos relacionados con cada casuística del problema. Un modelo matemático, o físico, constituye una descripción teórica del fenómeno a estudiar. Este modelo que describe el problema se usa para construir el modelo computacional del fenómeno. Un modelo computacional es un modelo limitado ya que las características de la computadora son limitadas. Tratar un problema computacionalmente a menudo encuentra restricciones temporales que hacen impracticable el estudio o los resultados. La solución para tratar estos modelos sometidos a estudio es el emplear computadoras de altas prestaciones (ampliar las restricciones computacionales del modelo) y emplear técnicas de codificación (traducción de los modelos matemático, físico al modelo computacional) específicas del campo de la supercomputación. El reciente avance experimentado por las arquitecturas de computadores hace que los procesadores se hayan convertido en...

A Comparative Study of Parallel Programming Languages: The Salishan Problems

Autor: J.t. Feo

Número de Páginas: 397

As execution speeds reach the physical limits of single cpu computers, the only hope of achieving greater computing power is with parallel systems. Researchers have proposed countless new programming languages, but their differences, similarities, strengths, weaknesses and problem domains are subtle and often not well understood. Informed comparison of parallel languages is difficult. This volume compares eight parallel programming languages based on solutions to four problems. Each chapter includes a description of the language's philosophy, semantics and syntax, and a solution to each problem. By considering solutions rather than language features or theoretical properties, the gap is bridged between the language specialists and users. Both professionals and students in the fields of computer and computational science will find the discussions helpful and understandable.
