Cilk Project - Concurrent language for parallel programming based on ANSI C. Source code, manual, papers and research into parallel chess programs. Petri Nets World - Petri Nets is a formal and graphical appealing language which is appropriate for modelling systems with concurrency. Esterel - One of a family of synchronous languages which are particularly well-suited to programming reactive systems, including real-time systems and control automata. Linda - Simple library implementation of the Linda parallel programming system. SourceForge project page: downloads, forum and CVS. LoI (Language of Interaction) - Designed to support interaction-oriented programming. This paradigm is especially suitable for the design of reactive component-based systems like distributed and interactive systems. NesC - A language for Deeply Networked Systems, implemented as a C extension based on structuring concepts and execution model of TinyOS, an event-driven OS for sensor network nodes with very limited resources: 8K bytes program memory, 512 bytes RAM. Joule - The Joule system is a foundation for building distributed applications. Joule Quick Reference 1.0 and The Joule Manual, divided into chapters as PDF files. Comega: Cω - C# extension, in two areas: Control flow extension for asynchronous wide area concurrency (was Polyphonic C#); Data type extension for XML and table manipulation (was Xen and X#). ChucK - Concurrent, time-based, on-the-fly, audio programming language, supports precise, fundamental level of expressiveness, multiple, simultaneous, dynamic control rates, ability to add, remove, modify code as programs run. FT Languages Page - Fault-tolerant projects, goal: enhance language support for distributed programs with FT needs, most high-level languages lack good support for such, more so at system level; 3 projects described, FT-SR, FT-Linda, FTAG. Libtask - A coroutine library for C and Unix. MC# - MC# (Multiprocessor C#) is a high-level object-oriented language based on .NET platform made for developing complex industrial program systems that can use multiprocessors. The Go Programming Language - Documentation, source, and other resources for Google's Go language. Go Programming Language Resources - Documentation, syntax highlighting files for various editors and IDEs, links to Go libraries and bindings to C libraries, etc. Bell Labs and CSP Threads - Resources about threaded programming in the Bell Labs CSP style, by Russ Cox: history, principles and style of concurrent programming practiced at Bell Labs. The Alef Concurrent Programming Language - Papers describing Plan 9's Alef programming language by Phil Winterbottom.
