There was a problem hiding this comment.
The speedups looks great! (And compilation time didn't seem affected on CI).
There seems to be some regressions for V100 for large batch sizes and K (like f16 fwd_gen B=256, M=1024, K=256), but the improvements on A100 are pretty amazing so let's get this in.

When we iterate on
key_start, we do the second matmul with V and stored the result into gmem after rescaling the current value. This did: gmem read/write + shmem read/write (due to the epilogue).This PR keeps everything in registers, and we only write to global memory at the end of the kernel.
