GPU Kernels for Block-Sparse Weights

OpenAi 2017 β€’ Scott Gray β€’ Alec Radford and Diederik P. Kingma

We’re releasing highly optimized GPU kernels for an underexplored class of neural network architectures: networks with block-sparse weights. The kernels allow for efficient evaluation and differentiation of linear layers, including convolutional layers, with flexibly configurable block-sparsity patterns in the weight matrix...
