This PR introduces the operator root mean square, `rms_norm`, into TOPI and relax, and its legalize transform.
* allow capturing input parameters in a cuda graph * remove unnecessary cudaGraphLaunch * support cuda graph for cutlass * add test * add test for cutlass * revert LiftTransformParams change * comment * update test * update builtin * update * delete exec properly * run cuda graph twice in the test to make sure cached launch works
This PR adds these features to the gradient system:
- Checkpointing for gradient pass
- `tvm.relax.testing.nn.checkpoint`
- `tvm.relax.op.grad.start_checkpoint` and `tvm.relax.op.grad.start_checkpoint`
- Support in the Gradient pass
- Fix several minor problems in op_gradient
…casting (apache#15330) This PR fixes a bug of the previous decode-GeMV dlight scheduling. Previously, when the inner dimension of the largest tensor is spatial, in the end the fused epilogue block was not bound to any thread axis, which is wrong and will generate wrong GPU code with wrong numerical results. That is because after doing reverse-compute-at of the epilogue block, there are at lease one remaining spatial axis, and such axis is supposed to be bound to threadIdx. This PR fixes this issue, and add three test cases which can cover both the reduction-inner and spatial-inner cases with or without broadcasting.

This PR introduces an utility pass that binds symbolic variables to user-provided integer values.
For example, say we have a following IRModule.
We can conveniently bind the symbolic variable by applying
After = relax.transform.BindSymVars("main", {"m": 10, "n": 10})(Before).This would be useful when specializing shape and providing compile-time shape info (e.g., model params or batch sizes) by eliminating the need to rewrite the model.
