Gpu gather scatter

WebGather/scatter is a type of memory addressing that at once collects (gathers) from, or stores (scatters) data to, multiple, arbitrary indices. Examples of its use include sparse … WebScatter. Reduces all values from the src tensor into out at the indices specified in the index tensor along a given axis dim . For each value in src, its output index is specified by its index in src for dimensions outside of dim and by the corresponding value in index for dimension dim . The applied reduction is defined via the reduce argument.
