Concurrency and Resource Architecture
Abstract
The concurrency architecture identifies the threads of execution, the allocation of software elements to those threads, specifies how the threads will be scheduled, and defines how resources will be shared among them.

This chapter discusses the definition of concurrency architecture in some detail, and provides a workflow for its full specification. Several design patterns are provided to address different issues that arise in multitasking systems. Exercises are provided for modeling the concurrency and resource architecture for the Roadrunner Traffic Light Control System ...
