FA3 can fail without a enough shared memory for some shapes, such as higher hidden_dim or some special cases. Right now, FA3 is supported for sm80/sm87 and sm86/sm89.

The main different Between sm80/sm87 and sm86/sm89 is the shared memory size. you can follow the link below for more information https://docs.nvidia.com/cuda/cuda-c-programming-guide/#shared-memory-8-x.

And for sgl-kernel right now, we can build FA3 on sm80/sm86/sm89/sm90a. That means if you use **A100(tested)**/A*0/**L20(tested)**/L40/L40s/**3090(tested)** you can use FA3.
