Pull Request resolved: #11825 ## Changes * Introduce `permute_buffer.glsl` and `permute_texture.glsl` compute shader templates to implement the permute operator ## Motivation The existing implementation of permute produced incorrect outputs for width packed textures. Furthermore, there was no buffer implementation for the permute operator. My goal with this diff is to introduce a more flexible implementation of permute that could work for any tensor representation. ## Performance impact None expected. ghstack-source-id: 292530157 @exported-using-ghexport Differential Revision: [D76483755](https://our.internmc.facebook.com/intern/diff/D76483755/)
Pull Request resolved: #11826 ## Changes * Allow test cases to specify storage types / memory layouts for individual args * Allow test cases to specify different data generation functions for individual args ## Motivation > Allow test cases to specify storage types / memory layouts for individual args Make it possible to test args that require specific storage types for certain input/output tensors. > Allow test cases to specify different data generation functions for individual args Useful for debugging operators during development. ghstack-source-id: 292530160 @exported-using-ghexport Differential Revision: [D77038777](https://our.internmc.facebook.com/intern/diff/D77038777/)
Pull Request resolved: #11827 ## Changes * Add implementation for the group norm operator. The operator is implemented via a 2 stage implementation. First, a reduction operator is executed to calculate the mean and standard deviation of each channel group. Then, the normalization is applied in an elementwise fashion. ghstack-source-id: 292530158 @exported-using-ghexport Differential Revision: [D77038778](https://our.internmc.facebook.com/intern/diff/D77038778/)
