WebGathers picklable objects from the whole group in a single process. Similar to gather(), but Python objects can be passed in. Note that the object must be picklable in order to be … Weband GPU, 2) prefetching regimes for gather/scatter, 3) compiler implementations of vectorization for gather/scatter, and 4) trace-driven “proxy patterns” that reflect the patterns found in multiple applications. The results from Spatter experiments show that GPUs typically outperform CPUs for these operations, and that Spatter can

WebMay 9, 2011 · The gridding convolution—the most challenging step—can be accomplished either in gather or scatter fashion. 32 For radial k-space sampling, the GPU rasterizer can also be used to perform the gridding convolution in a scatter fashion. 31 While gather and scatter are optimal with respect to either writing grid cells or reading k-space samples ... WebNov 16, 2007 · Gather and scatter are two fundamental data-parallel operations, where a large number of data items are read (gathered) from or are written (scattered) to given locations. In this paper, we study these two operations on graphics processing units (GPUs). With superior computing power and high memory bandwidth, GPUs have become a …
