GPars

GPars (Groovy Parallel Systems) brings a wide variety of high-level concurrency concepts, such as actors, parallel collections, agents, dataflow concurrency and other to Groovy developers. Leveraging the enormous flexibility of the Groovy programming language and building on proven Java ... [More] technologies, we aim to make concurrent programming for multi-core hardware intuitive, robust and enjoyable. [Less]

SwingWorker

SwingWorker is a framework for implementing 'long running Swing GUI interacting tasks'. This project is a back-port of SwingWorker from Java (TM) 1.6 release to Java (TM) 1.5 release.

python-csp

Implementation of Communicating Sequential Processes on top of Python.

JCarder

JCarder is an open source tool for finding potential deadlocks in concurrent multi-threaded Java programs. It does this by instrumenting Java byte code dynamically (i.e., it is not a tool for static code analysis) and looking for cycles in the graph of acquired locks. The only requirement is that ... [More] the program you want to analyze can be run in an ordinary JVM (compliant with Java 5.0 or higher). There is no need to use a special JVM or build procedure. [Less]

pycsp

The PyCSP project is an on-going project to bring CSP (Communicating Sequential Processes) to Python. It was started in 2006 and has been updated about every three month. Bug reports and suggestions for new features are most welcome. Example: import sys from pycsp import * @process def ... [More] source(chan_out): for i in range(10): chan_out("Hello world (%d)\n" % (i)) retire(chan_out) @process def sink(chan_in): while True: sys.stdout.write(chan_in()) chan = Channel() Parallel( 5 * source(-chan), 5 * sink(+chan) ) For a short introduction read this.

Kamaelia

Kamaelia is a general component framework for all programmers and maintainable development.

Virtual Object System (VOS)

VOS is a library and network protocol for interlinked object structures, which can be easily distributed over networks. Notifications of changes are automatically sent to other applications/clients. VOS simplifies concurrent asynchronous programming, both within the same process or distributed ... [More] over the network. Revision control (versions), access control, and other important features are built in. VOS object messaging also allows access from multiple languages. VOS forms the basis for several applications including multiuser 3D virtual reality, web content management, and any other application requiring an infrastructure for distributed, dynamic data structures. A multipurpose GUI client application for a combined 3D/2D/WIMP browsing and development environment is available. [Less]

ChanL

ChanL is a portable library for easy thread-based synchronous concurrency. ChanL uses channels as primitives for thread communication, and includes a thread pool implementation. It is designed with efficiency, portability, and ease-of-use in mind.
