Abstract Text Our ability to process large amounts of data and the size and number of data sets are growing at an incredible pace. This development presents us with the opportunity to build systems that perform complex analyses of increasingly dense networks of data. These opportunities include computing recommendations, analysing social networks, finding patterns in transaction networks, scheduling tasks, or inferencing probabilistic models. Many of these tasks involve processing data that has a natural graph representation. Whilst the opportunities are there in the form of access to processing resources and data sets, the way we write software has largely not caught up. Many use MapReduce for scalable processing, but this abstraction has shortcomings with regard to processing graph structured data, especially with iterative and asynchronous processing. This thesis introduces the SIGNAL/COLLECT programming model and framework for efficient parallel and distributed large-scale graph processing. We show that this abstraction captures the essence of many algorithms on graphs in a concise and elegant way. Beyond that, we also show implementations of two complex systems built on SIGNAL/COLLECT: The first system is TripleRush, a distributed in-memory triple store with a novel architecture. The second system is foxPSL, a distributed proba- bilistic inferencing system. Our evaluations show that the SIGNAL/COLLECT framework can efficiently execute simple graph algorithms such as PageRank and that the two complex systems also have competitive performance relative to the respective state-of-the-art. For this reason we believe that SIGNAL/COLLECT is more generally suitable for designing scalable dynamic and complex systems that process large networks of data.
