Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for parallelizing convolution processing. An exemplary method comprises: segmenting an input tensor into a plurality of sub-tensors and a plurality of filters into a plurality of sub-filter groups; respectively assigning a plurality of combinations of the sub-tensors and the sub-filter groups to a plurality of processors; storing, by each of the plurality of processors, non-zero values of the sub-tensor and the sub-filter group in the assigned combination as index-value pairs; parallelly performing for a plurality of iterations, by the plurality of processors, multiply-and-accumulate (MAC) operations based on the index-value pairs to obtain a plurality of outputs, where the index-value pairs of the sub-filter groups are rotated among the plurality of processors across the plurality of iterations; and aggregating the plurality of outputs as an output tensor.
