This paper develops and evaluates search and optimization techniques for autotuning 3D stencil (nearest neighbor) computations on GPUs. Observations indicate that parameter tuning is necessary for heterogeneous GPUs to achieve optimal performance with respect to a search space. Our proposed framework takes a most concise specification of stencil behavior from the user as a single formula, autogenerates...
Data-parallel languages feature fine-grained parallel primitives that can be supported by compilers targeting modern many-core architectures where data parallelism must be exploited to fully utilize the hardware. Previous research has focused on converting data-parallel languages for SIMD (single instruction multiple data) architectures. However, directly applying them to today's SIMT (single instruction...
Document clustering plays an important role in data mining systems. Recently, a flocking-based document clustering algorithm has been proposed to solve the problem through simulation resembling the flocking behavior of birds in nature. This method is superior to other clustering algorithms, including k-means, in the sense that the outcome is not sensitive to the initial state. One limitation of this...
