Is there any block/warp/instruction shape list for SIMT documented like other op code class?

[TigerYang414]

Other opcode shapes is listed with details in doc:https://github.com/NVIDIA/cutlass/blob/master/media/docs/functionality.md

Could we add SIMT related shapes in it?

there are many more available simt tile sizes than tensor op. Here are some plausible ones for sm80 sgemm.

for example, in

TileDescription([256, 128, 8], 5, [4, 2, 1], math_inst, min_cc, max_cc),

[256, 128, 8] is the threadblock tile size
[4, 2, 1] is warp count size. warp tile size is then 256/4 = 32, 128/2=64, 8/1=8
5 is stage number
