 * **`precision`** - You can specify the precision of tensor by `precision=fp32`. Currently all of our reported results are `fp32` but we added support for `fp16` & `bf16`.
 *  **`backend`** - We are also supporting other GPU programming languages beyond `cuda`. Simply specify `backend=triton`. For now we support DSLs: `cuda`, `triton`, `cute`, `tilelang`.
