class wave_lang.kernel.wave.wave.LaunchableWave(constraints: list[Constraint] | None, name: str, eager_function: Callable[[Any], Any])

create_induction_vars(trace: CapturedTrace) → None

Creates induction variables for all the reductions in the graph and associates tiling constraints all the reduction dimensions with the appropriate induction variables.

property device_constraints: list[DeviceConstraint]

eager_execute(args, kwargs)

get_workgroup_dims() → list[int]

Returns the workgroup dimensions that are not aliased.

property hardware_constraints: list[HardwareConstraint]

infer_device_layout(idxc: IndexingContext)

infer_grid_shape(idxc: IndexingContext)

initialize_reductions(trace: CapturedTrace) → None

For each reduction, initializes the reduction count by looking at the tiling constraints associated with the reduction.

initialize_symbolic_constraints() → None

For each symbolic constraint, create new constraints for the related symbolic values with appropriate substitutions.

initialize_wave_constraints() → None

For each wave constraint, determines the appropriate wave id by looking for workgroup constraints along the same dimension and using information from the hardware constraints.

initialize_workgroup_constraints() → None

For kernels that distribute more than three dimensions among workgroups, we need to update the workgroup constraints for dimensions >= 2 with the appropriate workgroup index.
