A Distributed and Parallel Component Architecture for Stream-Oriented Applications

Abstract. This paper introduces ThreadMill - a distributed and parallel component architecture for applications that process large volumes of streamed (time-sequenced) data, such as is the case e.g. in speech and gesture recognition applications. Many stream-oriented applications offer ample opportunity for enhanced performance via concurrent execution, exploring a wide variety of parallel paradigms, such as task, data and pipeline parallelism. ThreadMill addresses the challenges of development and evolution of parallel and distributed applications in this domain by offering a modeling formalism, a programming framework and a runtime infrastructure. Component development and reuse, and application evolution are facilitated by the isolation of communication, concurrency, and synchronization concerns promoted by ThreadMill: 1) communication between components is mediated, so that components are oblivious to who their peers in an application are, allowing them to be composed in unanticipa...
