dc.description.abstractThis paper addresses optimizing the execution of range queries into multi-dimensional datasets on distributed memory parallel machines within the Active Data Repository framework. ADR is an infrastructure that integrates storage, retrieval and processing of large multi-dimensional datasets on distributed memory parallel architectures with multiple disks attached to each node. We describe three potential strategies for efficient execution of such queries that employ different tiling and workload partitioning approaches. We evaluate scalability of these strategies for different application scenarios, varying both the number of processors and the input dataset size on a 128 processor IBM SP multicomputer.
