Summary: Fixes a couple tutorial assumptions, most notably: 1. It only worked with fp8 and fp16. Now it works with all dtypes for OmniFm. 2. The shapes were not compatible due to layout mismatches. Since every shape will have a layout mismatch this adds an explicit tranpose to allow benchmarking a "best case" although this may not be accurate. 3. Some shapes will never be compatible with TMA as the strides are not divisble by 16. I added an explicit check in the code to simplify this issue, but I will be skipping these. Differential Revision: D77950060
Summary: Many of the shapes performed much worse, which may be due to the tutorial assuming large configs. This adds smaller configs as an option so we can test warp spec vs just the impact of blackwell configs. Reviewed By: PaulZhang12 Differential Revision: D78059342
