Easy concurrency

Advances in technology raise expectations. As far as software engineering is concerned, the common expectation is that coding and deploying applications is going to be simple. It seems, though, that software engineering is not getting easier, and the complexity moves to an application domain. One of the sources of complexity is an application concurrency. It is not an uncommon development practice that concurrency and transaction management in multi-user, multi-threaded, event-driven applications are postponed until after most of the required functionality is implemented. This situation has various explanations. On the one hand, business logic may require access and modification of large sets of inter-connected application objects. On the other, testing and stress-testing of this logic becomes possible only at advanced stages of product development. At these stages, increasing lock granularities may appear to be less "expensive" than debugging race conditions and deadlocks. Coarse-grained locking has, of course, an adverse effect on application scalability. Declaring rules of concurrency outside of the application may solve part of the problem. This paper presents an approach allowing developers to define concurrency in application-specific terms, design it in the early stages of development, and implement it using a documented API of the concurrency engine (CE). Simple notation makes it possible to record concurrency specifications in terms of application operations, relationships between application resources, and synchronization conflicts between operations. These concepts are demonstrated on examples. The final sections include the CE UML diagram, notes on API usage, and performance benchmarks. Published online: 25 July 2001
