In the late s, hardware designers developed multiple processor machines. This presented not only a challenge for operating systems designers but also an opportunity that application programmers could exploit.

To hamess the chal- lenge, people developed synchronization primitives such as semaphores and monitors to simplify the programmer's task. By the mids, people came to appreciate the necessity of using formal methods to help control the inherent complexity of concurrent programs. Computer networks were introduced in the late s and early s.

The Arpanet supported wide-area computing, and the Ethernet established local-area networks. Networks gave rise to distributed programming, which was a major topic of the s and became even more important in the s.

The essence of distributed programming is that processes interact by means of message passing rather than by reading and writing shared variables. Now, at the dawn of a new century, we have seen the emergence of mas- sively parallel processing—in which tens, hundreds, or even thousands of proces- sors are used to solve a single problem.

Concurrent hardware is more prevalent than ever, and concurrent programming is more relevant than ever. This is my third book, another attempt to capture a part of the history of concurrent programming.

My first book—Concurrent Programming: Principles and Practice, published in —gives a broad, reference-level coverage of the period between and , Because new problems, programming mecha- nisms, and formal methods were significant topics in those decades, the book focuses on them.

My second book—The SR Programming Language: Concurrency in Prac- tice, published in —summarizes my work with Ron Olsson in the late s and early s on a specific language that can be used to write concurrent pro- grams for both shared- and distributed-memory machines.

The SR book is prag- matic rather than formal, showing how to solve numerous problems in a single programming language. I have drawn heavily from material in the Concurrent Programming book, but I have completely rewritten every section that I have retained and have rewritten examples to use pseudo-C rather than SR.

Thave added new material throughout, especially on parallel scientific program- ming. Ihave also included case studies of the most important languages and soft- ware libraries, with complete sample programs. Finally, I have a new vision for the role of this book—in classrooms and in personal libraries. A New Vision and Role Parallel and distributed computing are today pervasive concepts. As usual in computer science, advances have been led by hardware designers, who keep building bigger, faster, more powerful computers and communication networks.

For the most part, they are succeeding—witness the stock market! New computers and networks create new challenges and opportunities, and for once software designers are no longer all that far behind.

These software products are specifically designed to take advantage of concurrency in hardware and applications. In short, much of the computing world is now concurrent! Preface vii Reflecting the history of the topic, operating systems courses lead the way— covering topics like multithreading, communication protocols, and distributed file systems.

Architecture courses cover multiprocessors and networks, Compilers courses cover compilation issues for parallel machines. Theory courses cover models for parallel computing. Algorithms courses cover parallel algorithms. Database courses cover locking and distributed databases. Graphics courses make use of parallelism for rendering and ray tracing. The list goes on. In addi- tion, concurrent computing has become a fundamental tool in a wide range of science and engineering disciplines.

Whenever a topic in com- puting has become pervasive, as concurrency surely has, we have added founda- tion courses to provide students with basic knowledge of a topic. Similarly, whenever a topic has become well understood, as concurrency now is, we have migrated the topic to the core curriculum. Ihave tried to cover those aspects of parallel and distributed computing that I think every computer science student should know.

This includes basic princi- ples, programming techniques, major applications, implementations, and perfor- mance issues. Each case study describes relevant parts of the language or library and then presents a com- plete sample program. In addition, summarize several additional languages, models, and tools for parallel scientific computing in Chapter On the other hand, no single book can cover everything—and still be afford- able—so students and instructors may wish to augment this text with others.

The Historical Notes and the References at the end of each chapter describe additional material and provide pointers for further study. Content Overview This book contains 12 chapters.

Chapter 1 summarizes basic concepts of concur- rency, hardware, and applications. The last section of Chapter 1 summarizes the programming notation that is used in the text.

Part describes con- current programming mechanisms that use shared variables, and hence that are directly suitable for shared-memory machines. Chapter 2 introduces fundamental concepts of processes and synchronization; the chapter uses a series of examples to illustrate the key points and ends with a discussion of the formal semantics of concurrency.

Understanding the semantic concepts will help you understand parts of later chapters, but it should also be sufficient to refer back to them when necessary. Chapter 3 shows how to implement and use locks and barriers; it also describes data parallel algorithms and a parallel programming technique called a bag of tasks. Chapter 4 describes semaphores and gives numerous examples of how to use them. Semaphores were the first high-level concurrent programming mechanism and remain one of the most important.

Chapter 5 covers monitors in detail. Monitors were introduced in a seminal paper, somewhat lost favor in the s and early s, but have regained importance with the Java language. Finally, Chapter 6 describes how to implement processes, semaphores, and moni- tors on both uniprocessors and multiprocessors.

Part 2 covers distributed programming, in which processes communicate and synchronize by means of messages. Chapter 7 describes message passing using send and receive primitives. It shows how to use these primitives to program filters which have one-way communication , clients and servers which have two-way communication , and interacting peers which have back and forth communication. Chapter 8 examines two additional communication primitives: remote procedure call RPC and rendezvous.

With these, a client process initi- ates a communication by issuing a cal1—which is implicitly a send followed by a receive; the communication is serviced either by a new process RPC or by a rendezvous with an existing process. Chapter 9 describes several paradigms for process interaction in distributed programs.

Finally, Chapter 10 describes how to implement message passing, RPC, and rendezvous. That chapter also shows how to implement what is called a distributed shared memory, which supports a shared-memory programming model in a distributed environment.

Part 3 covers parallel programming, especially for high-performance scien- tific computations. Many other kinds of parallel computations are described in earlier chapters and in the exercises of several chapters. Parallel programs are written using shared variables or message passing; hence they employ the techniques described in Parts 1 and 2.

Chapter 11 examines the three major classes of scientific computing applications: grid, particle, and matrix computations. These arise in simulating modeling physical and biological- systems; matrix computations are also used for such things as eco- nomic forecasting. Chapter 12 surveys the most important tools that are used to write parallel scientific computations: libraries Pthreads, MPI, and OpenMP , parallelizing compilers, languages and models, and higher-level tools such as metacomputations.

The end of each chapter provides historical notes, references, and an exten- sive set of exercises. The historical notes summarize the origin and evolution of each topic and how the topics relate to each other.

The notes also describe the papers and books listed in the reference section. The exercises explore the topics covered in each chapter and also introduce additional applications.

Foundations of Multithreaded, Parallel, and Distributed Programming

Distributed computing is a field of computer science that studies distributed systems. A distributed system is a system whose components are located on different networked computers , which communicate and coordinate their actions by passing messages to one another from any system. Three significant characteristics of distributed systems are: concurrency of components, lack of a global clock , and independent failure of components. A computer program that runs within a distributed system is called a distributed program and distributed programming is the process of writing such programs. Distributed computing also refers to the use of distributed systems to solve computational problems.

Greg Andrews teaches the basic ideas of multithreaded, parallel and allotted computing and relates them to the implementation and function approaches. He offers the proper breadth of themes and helps those discussions with an emphasis on functionality. Show description.

Parallelism and distribution of processing; software bus concept; patterns in software design. The course provides an in-depth discussion of the software systems with multiple processes and of the relationship between concurrency and distribution of processes. The concept of the software bus, the existing standards, and the issues associated with their implementation are covered. Academic dishonesty will be "rewarded" with a grade of "F".

Ни у кого не вызывало сомнений, что Стратмор любит свою страну. Он был известен среди сотрудников, он пользовался репутацией патриота и идеалиста… честного человека в мире, сотканном из лжи. За годы, прошедшие после появления в АНБ Сьюзан, Стратмор поднялся с поста начальника Отдела развития криптографии до второй по важности позиции во всем агентстве. Теперь только один человек в АНБ был по должности выше коммандера Стратмора - директор Лиланд Фонтейн, мифический правитель Дворца головоломок, которого никто никогда не видел, лишь изредка слышал, но перед которым все дрожали от страха.

Ну и порядки. Звук мотора, похожий на визг циркулярной пилы, заставил его повернуться. Парень крупного сложения и прильнувшая к нему сзади девушка въехали на стоянку на стареньком мотоцикле Веспа-250. Юбка девушки высоко задралась от ветра, но она не обращала на это ни малейшего внимания.

Они держали ее что было сил, но сопротивление оказалось чересчур сильным и створки снова сомкнулись. - Подождите, - сказала Сьюзан, меняя позицию и придвигаясь ближе.  - Хорошо, теперь давайте.
