Analysis of large sensor datasets for structural and functional features has applications in many domains, including weather and climate modeling, characterization of subsurface reservoirs, and biomedicine. The vast amount of data obtained from state-of-the-art sensors and the computational cost of analysis operations create a barrier to such analyses. In this paper, we describe middleware system support to take advantage of large clusters of hybrid CPU-GPU nodes to address the data and

... intensive requirements of feature-based analyses in large spatio-temporal datasets. 1 Spatio-temporal datasets contain data elements, which are associated with coordinates in a multi-dimensional space with lowdimensionality and potentially obtained at multiple time steps.
