MSc in Computer Science Term Hilary Term 2010  (16 lectures) Overview Many challenges arise during the design and implementation of concurrent and distributed programs. The aim of this course is to understand those challenges, and to see techniques for tackling them. The main paradigm to be considered is message passing concurrency, where independent processes, with private variables, interact by passing messages. Learning outcomes At the end of the course students are expected to understand: The conceptual foundations of concurrent programming, and A variety of effective ways of structuring concurrent and distributed programs. Prerequisites Students should have an understanding of CSP, e.g. as taught in the Concurrency course. Students should also have a good understanding of Object Oriented Programming, e.g. as taught in the Michaelmas Term OOP course. Students who have learnt either CSP or OOP elsewhere should discuss their experience with the lecturer before taking this course. The course will have a number of practicals, to allow students to gain experience with concurrent programming. These practicals will use Scala; background reading on the language will be suggested.

Issues in Concurrent Programming var addthis_pub="ychandras"; Issues in Concurrent Programming Introduction The term concurrent programming usually refers to the kind of programming required to support simultaneous activities in a software application. Such a definition is somewhat broad, and indeed concurrent programming can refer to a variety of programming models. For example, multi-processor systems, parallel systems, distributed systems as well as uni-processor systems with simulated concurrency - all these platforms support concurrent programming. In this article, we take particular emphasis on the uni or multi- processor system with actual or simulated concurrency. Many of the issues we handle here are general and can be applied to the other systems as well. Concurrent programming, as we take focus here, is the set of techniques and tools used in programming concurrent activities that dynamically share information with one another. Note that dynamic information sharing is an important criteria. Otherwise programming two different programs running on two different machines would qualify as concurrent programming under an indiscriminate definition.

ConcurrentProgramming.org exists to provide information, libraries, and advice on topics related to concurrent programming. Feel free to browse, use, and contribute to this site. What is ConcurrentProgramming If you are new to software development, you may be asking yourself what is ConcurrentProgramming? We consider ConcurrentProgramming to be the act of developing software which may execute certain actions in parallel. I stress the may in the above statement. Applications need to efficiently use the resources provided by the system executing the application. Concurrent applications need to determine the most efficient execution method. The astute reader may ask, what do you mean by efficient? Well, that depends. Efficient could mean total execution time. It could also mean maximized throughput. Could it mean memory consumption? You bet. When I say the word efficient, it takes on different meanings depending upon the context of the application. Thus, Concurrent Programming is the process of developing applications that maximize efficiency on systems with the ability to execute various numbers of concurrent actions.

This is clearly of increasing importance due to multi-core. This includes a tutorial of the entire set of Windows and .NET APIs required to write concurrent programs. Interspersed among the tutorial are many difficult-to-discover internal details about how things work. Because so much of the threading and synchronization features of the platform are Windows-general, I try to focus on the general behavior first and the API details of native and managed code second. That are also several practical parallelism algorithms and data structures used for illustration, and best practices and practical topics like debugging and performance. My goal was to treat readers to enough computer-sciency material so that they understand the rich history and evolution of concurrency, but to avoid too much formalism so that professional developers aren’t overwhelmed with theory that isn't directly relevant to actual programming.

Concurrent Programming in Erlang J. Armstrong, R. Virding, C. Wikström, M. Williams 2:nd Edition Prentice Hall, 1996, ISBN 0-13-508301-X Erlang is a concurrent functional programming language designed for programming large industrial real-time systems. Erlang is dynamically typed and has a pattern matching syntax. Functions are defined using recursion equations. Erlang provides explicit concurrency, has asynchronous message passing and is relatively free from side effects. Distributed Erlang programs can run transparently on cross-platform multi-vendor systems. The language has primitives for detecting run-time errors and for dynamic code replacement (i.e. changes to code can be made in a running real-time system, without stopping system). Erlang has real-time GC, modules and a foreign language interface. Erlang was developed at the Ellemtel Telecommunication Systems Laboratories and is used within Ericsson for product development and prototyping. Part I. Programming.

WARNING: UNATTENDED SOFTWARE These web pages and associated software are no longer being maintained. You are welcome to browse and download, but no support is available. The SR Programming Language SR (Synchronizing Resources) is a language for writing concurrent programs. The main language constructs are resources and operations. Resources encapsulate processes and variables they share; operations provide the primary mechanism for process interaction. SR provides a novel integration of the mechanisms for invoking and servicing operations. Consequently, all of local and remote procedure call, rendezvous, message passing, dynamic process creation, multicast, and semaphores are supported. SR also supports shared global variables and operations. SR has been used at a number of universities and labs for course work and research projects involving concurrent programming. It has been used in concurrent programming courses to reinforce concepts with small programming projects and with larger projects such as experiments with parallel algorithms, replicated databases, distributed simulations, and parts of distributed operating systems such as file systems and command interpreters. SR has also been used as a tool in several masters theses and doctoral dissertations to conduct experiments in parallel and distributed programming and to implement larger systems such as a system for mixed language programming, one for distributed implementation of graph algorithms, experiments with load balancing algorithms, and experiments with upcall program structures.
