Acceleration of Multiresolution Imaging Algorithms: A Comparative Study

—In this paper we consider a multiresolution filter and its realization on the Cell BE and GPUs. We not only present common and specific optimization strategies undertaken for obtaining maximum performance on these architectures, but also how to obtain a speedup of 6.57x and 33.24x compared to an optimized OpenMP baseline implementation. Furthermore, we also undertake automated configuration space exploration of different partitioning possibilities for selection of best tiling parameters.
