Tools, process algebras, etc.Edit

Concurrency tools:

• CADP, a widespread toolbox for the Construction and Analysis of Distributed Processes.
• CWB (Edinburgh Concurrency Workbench) automated toolset. See also the Concurrency Factory and CWB-NC (The Concurrency Workbench of North Carolina), which includes a LOTOS interface, diagnostic infomation, etc. Note: The CWB and CWB-NC have a common ancestor, but are each under separate development.
• Concurrency Factory, a "next generation" Concurrency Workbench toolkit.
• Circal (CIRcuit CALculus) System supporting a process algebra which may be used to rigorously describe, verify and simulate concurrent systems. See software.
• DI2PN tool. Delay Insensitive circuits and Petri Nets.
• FDR2 (Failures-Divergence Refinement) for CSP.
• LTSA (Labelled Transition System Analyser), a verification tool for concurrent systems. See also associated Concurrency: State Models & Java Programs book by Jeff Magee and Jeff Kramer (published by Wiley, 1999).
• Meije tools for the verification of concurrent programs. It contains: ATG, an X-based editor for labelled automata and networks of synchronized automata; Mauto, a tool for computing transition systems from programs in CCS, Basic Lotos, Meije, or Esterel, reducing them along various bisimulations; Hoggar, a batch tool for fast reduction (for strong, weak, and branching bisimulations) of systems described in FC2 format, using either BDDs or explicit representations.
• TAPAs (Tool for the Analysis of Process Algebras): TAPAs aim is to support teaching of process algebras. It can be use to specify and analyze concurrent systems. Systems are described as process algebras terms that are then mapped to Labelled Transition Systems (LTSs). Properties can be verified by checking equivalences between concrete and abstract system descriptions, or by model checking temporal formulas over the obtained LTS. A key feature of TAPAs, that makes it particularly suited for teaching, is that it maintains a consistent double representation of each system: both graphical and textual.
• VERSA — Verification Execution and Rewrite System for ACSR.

Process algebras:

• Algebra of Communicating Shared Resources (ACSR) based on CCS from the Real-Time Systems Group , University of Pennsylvania, USA.
• CCS (Calculus of Communicating Systems).
• CSP (Communicating Sequential Processes). See also FDR tool.
• μCRL (micro CRL), process algebraic language for communicating processes with data.
• LOTOS (Language Of Temporal Ordering Specification - ISO standard 8807). See also the CADP toolset and the LOTOS NT language supported by this toolset.
• Pi-calculus, a calculus for mobile processes. See also papers by Robin Milner et al. the Mobility Workbench (see README file) and a BibTeX bibliography.

Development methods:

• BSP Model (Bulk Synchronous Parallel Computing) and the BSP Library. An approach to portable and predictably-efficient parallel computing by Oxford Parallel.
• `pobl', a development method for concurrent (object based) programs.
• UNITY, a programming notation and a logic to reason about parallel and distributed programs.
