I'm trying to learn to develop Cutlass based kernels for B200 GPU using A tile from tensor memory and B tile from shared memory, but internet has no example code to tell how to move A tile from smem to tmem and how to call gemm.

Blackwell Cutlass experts, do you know a simple kernel code for B200. There are _SS versions and I tested them but now I need _TS version.

When new version comes, the previous loses performance. Right now opus 4.8 is 3x slower and 2x less brain than 3 weeks ago.

I just need to keep what was working fine. I dont want constant updates with performance losses. What to do?
