Abstract:	The article discusses the design of a concurrent and distributed control system. The approach described in this article is based on the concept of patterns and pattern language. The G++ pattern language addresses the problem of designing large software control systems, made up of layers of concurrent control modules installed on a distributed computer architecture by following an evolutionary development process that derives the final implementation from a prototype of the logical design. The language is derived from the "divide and conquer" paradigm and deals with issues such as the organization of control modules in a hierarchy of inclusion and use relationships, and the visibility requirements between the control modules, concurrency, and distribution. The article presents a summary of the G++ pattern language for concurrent and distributed systems, the result of experience acquired from real-world projects over the last 10 years. The existence of design patterns is often very valuable for solving isolated design problems. A domain-specific pattern language does the same to a whole development project. Typically, engineers without experience with object-oriented programming or concurrent/distributed systems are able to develop systems of significant complexity after a period of three months.
