Analyzing Concurrency in Streaming Applications
We present a concurrency model that allows reasoning about concurrency in executable specifications of streaming applications. It provides measures for five different concurrency properties. The aim of the model is to provide insight into concurrency bottlenecks in an application and to provide global direction when performing implementation-independent concurrency optimization. The model focuses on task-level concurrency. A concurrency optimization method and a prototype implementation of a supporting analysis tool have been developed. We use the model and tool to optimize the concurrency in a number of multimedia applications. The results show that the concurrency model allows target-architecture-independent concurrency optimization.
