…e… (triton-lang#2283) …rf on problems that need few blocks. constrain the number of launched blocks to what it exactely needs for persistent warp specialized kernel. It's useful when problems need very few blocks. e.g. MxNxK=800x800x60000, f16_f16_f32, block size=128x128x64, non-split-k. Experiments show it can achieve ~16% speedup.
