WebScan operation Similar to the global reduction, the top-level strategy is perform local scan within each block add on sum of all preceding blocks Will describe two approaches to the local scan, both similar to the local reduction first approach: very simple using shared memory, but O(N logN) operations second approach: WebPixelShuffle. Rearranges elements in a tensor of shape (*, C \times r^2, H, W) (∗,C × r2,H,W) to a tensor of shape (*, C, H \times r, W \times r) (∗,C,H ×r,W × r), where r is an upscale factor. This is useful for implementing efficient sub-pixel convolution with a stride of 1/r 1/r. See the paper: Real-Time Single Image and Video Super ... WebShuffler¶ class torchdata.datapipes.map.
