We present how to efficiently mine a set of directed acyclic graphs (DAGs) for unconnected, both multi-or single-rooted, and induced fragments. With a new canonical form that is based on the nodes' topological levels, our miner is faster and uses less storage than general purpose gSpan (Yan, X. and Han, J., 2002). Moreover, it can base support resp.(More)
The potential of heterogeneous multicores, like the Cell BE, can only be exploited if the host and the accelerator cores are used in parallel and if the specific features of the cores are considered. Parallel programming , especially when applied to irregular task-parallel problems, is challenging itself. However, heterogeneous multicores add to that(More)
