WebFeb 28, 2024 · The ifft is computed in a data-parallel way but there is no overlap between the computations being run on different workers that share a GPU. Some overheads will be reduced but the main gains you see will be the fact that you have 4 GPUs. WebGPU-enabled functions run on the GPU only when the input data is on the GPU. The data type of parameter arguments such as dimensions or indices do not affect where the function is run. For example, the sum function in this code runs on the GPU because the data, the first input, is on the GPU. A = rand (10); d = 2; sum (gpuArray (A),d);
