However, the current Java specification does not adequately provide for the protection of shared resources or for deadlock detection, two of the most common problems arising from parallel programs. The ability to solve these problems is crucial for Java concurrent programming.

Crossroads Extending Java to Support Shared Resource Protection and Deadlock Detection in Threads Programming by Anita J. Van Engen Michael K. Bradshaw Nathan Oostendorp Abstract Java threads enable programmers to write parallel programs very easily and conveniently. However, the current Java specification does not adequately provide for the protection of shared resources or for deadlock detection, two of the most common problems arising from parallel programs. The ability to solve these problems is crucial for Java concurrent programming. In this paper, we introduce and implement a model that can aid in writing parallel programs by providing shared resource protection and deadlock detection. Introduction The increasing use of parallel systems and programs in many different fields has brought new attention to how threads cooperate and share data. Parallel programs are used in such critical and sensitive environments as database operation and manipulation, data collection and system maintenance tasks. With an increasing emphasis being placed on the World Wide Web and on platform-independent tools, Java is positioned to become the language of choice for many applications, including parallel programming. While it provides some solid facilities for basic threads programming, Java does not adequately provide for shared resource protection or have the ability to detect deadlock. Adequate Java support for these features would make Java threads even more effective for parallel programming.

Lyric is a concurrent programming language, which is under development at Myricom for use on multicomputers based on Myricom's LANai chipset. While every effort is being made to provide prototype software and documentation consistent with the future versions of lyric, the prototype software and documentation provided here are subject to change without notice. Compiler The lyric compiler, which is a modified version of gcc-2.7.2 is available as a gzipped tar file The lyric compiler is installed just as gcc using prefix to specify where the compiler should be installed, as follows: configure prefix= prefix make install Only the SPARC architecture is currently supported. This installation process has only be tested under SunOS4.1.3 using Gnu make. Installation might work under Solaris on a SPARC, but this hypothesis is untested. For some newer flavors of SunOS, you must use instead of make install . Please report any installation problems to Myricom's lyric maintainers at lyric@myri.com The Lyric compiler source contains the lyric runtime system library and all header files needed to compile and run lyric programs, and should install them automatically. In the runtime system included with this compiler, "Class processes" are not implemented exactly as described in the lyric documentation below. Classes are implemented as objects rather than processes. Consequently, you may only invoke class methods synchronously, and class objects cannot use the active/passive mechanisms. This discrepancy does not affect the examples presented in the documentation, but can cause fatal runtime-system errors if these class objects attempt to send messages larger than about 100 bytes. (Instance processes may send any size message, however, within the limits of available memory.)

(c) 2002 Mulle kybernetiK - text by Nat! Concurrent Programming, a quick refresher As you know, you should protect shared mutable data with locks as explained in Cocoa/TasksAndConcepts/ProgrammingTopics/Multithreading . Even just incrementing a global variable is not thread safe at all. This one C-instruction is actually executed with three or more PPC instructions that look similar or identical to this: lwz r11,0(r9) addi r0,r11,1 stw r0,0(r9) While each PPC instruction is executed there is a possibility that an interrupt occurs. The processing of this thread will then be suspended and the processor's attention will be focused on another thread. This other thread might very well now execute the same code trying to access the same global variable! To show how this can be disastrous, lets examine two cases where two threads execute the same code. In the first example the context switch to the second thread is harmless, because the increment statements have completed:

55. Concurrent Programming In ML (Abstract) concurrent programming in ML (Abstract). Programs written in functionallanguages seldom use side effects. This makes functional http://www.eecs.harvard.edu/~nr/pubs/concurrent-abstract.html

Concurrent programming in ML (Abstract) Programs written in functional languages seldom use side effects. This makes functional programs good candidates for concurrent execution, since computations without side effects can proceed concurrently without interfering. Some side effects are required for I/O and communication; we can introduce them in a disciplined way by adding message-passing primitives to a functional language. Although ML is not purely functional, it is especially well suited to concurrent programming because it has a safe polymorphic type system and garbage collection. Following the examples of Pike's Newsqueak and Hoare's CSP, I have added concurrent primitives to ML, using the Standard ML of New Jersey compiler. The primitives provide dynamic creation of processes and channels and synchronous communication over channels. Input and output (to the Unix file system) is available on the same footing as communication over channels. I use SML-NJ's callcc and throw to simulate concurrent execution on a sequential machine. Concurrent programs can be structured as large collections of simple processes. I present several example processes. Because they are polymorphic (i.e. they operate on values of any type), these processes can be used in many programs. I present an application that uses these processes. I comment on the implementation and suggest how it might be extended to run on a multiprocessor. I show how the Standard ML modules system can be used to effect changes in the meanings of the primitives.

U NIT O UTLINES home undergraduate Concurrent Programming Concurrent Programming Homepage Concurrent Programming (230.304) 6 points / Semester 1 Handbook Description Investigating techniques for performing computations using more than one processing agent is the prime focus of this unit. The overall objective of concurrent programming is to increase computing efficiency in executing a task by appropriately coordinating the activities of multiple processes, each computing part of the solution to the task. The purpose of this unit is to expose the issues involved in concurrent programming both from practical and theoretical standpoints. After introducing a model used as a basis for analysing concurrency, topics including concurrent algorithms, architectures and programming languages are addressed. A series of tutorials and laboratories based on a concurrent language, give further theoretical and practical exposure to concurrency. Prerequisites Unit Aims The need to understand and work with the notion of concurrency is becoming increasingly important as the processing limits of sequential programs on sequential machines begin to be reached. Thus multiprocessor configurations are now commonplace in large-scale computing environments. However, these multiprocessor systems generally run sequential application programs: it is the operating system that embodies principles of concurrency. With the advent of low cost multiprocessor systems (eg Transputer) on the one hand and massively parallel systems (eg Ncube) on the other, the responsibility of extracting maximum utilization of these systems is increasingly falling upon the application developer. The focus of this unit will be the i understanding and designing of concurrent systems. Time permitting, consideration will also be given to massively parallel systems such as artificial neural networks.

Home Page Reviews Main Book Review Concurrent Programming in Java 2ed by Doug Lea Highly Recommended ISBN: Publisher: Addison-Wesley Pages: Price: Categories: java parallel systems Reviewed by Ian Bolland in C Vu 12-4 (Jul 2000) Most treatments of Java multi-threading follow the same lines. They present a small example, often a variant of debit- credit, to show the dangers of letting multiple threads access the same variable at the same time and then go on to recommend synchronised methods as the solution to the problem. Now as far as it goes, this is good advice. However synchronised methods are not always the best solution to concurrency problems. Firstly, synchronisation adds an overhead to method calls and this penalises all clients; even those who do not require thread safety. Secondly, it opens up the possibility of deadlock and a lot of effort may be required to prevent deadlock. Finally, it does not by itself prevent clients from getting erroneous results. For example, consider the following code to process all elements in a Vector vec: If other threads are simultaneously modifying vec , this loop may process elements twice, may skip elements and may throw an
