Motivation. Figure 1 presents a motivating example of the optimization permute_linear_fusion in PyTorch Inductor (PyTorch, 2023b).This optimization fuses the permute and linear operators when the permute method is invoked on an input tensor with more than two dimensions, specifically swapping the last two dimensions. On the left side of the figure, we see its source code implementation.
