Dispatches an SM100 matmul through the heuristic outlier config set.

Wraps select_and_launch_sm100_config with a launch callback that invokes _matmul_dispatch_sm100 (the epilogue-aware SM100 tile GEMM launcher) for each selected config.

Parameters:

c_type (DType): Output element type (inferred).
a_type (DType): Element type of the LHS operand a (inferred).
b_type (DType): Element type of the RHS operand b (inferred).
transpose_b (Bool): Whether b is stored transposed (defaults to True).
elementwise_lambda_fn (Optional[def[dtype: DType, width: SIMDLength, *, alignment: Int = Int(1)](IndexList[Int(2)], SIMD[dtype, width]) capturing thin -> None]): Optional epilogue applied to each output element (defaults to None).
elementwise_compute_lambda_fn (Optional[def[dtype: DType, width: SIMDLength, *, alignment: Int = Int(1)](IndexList[Int(2)], SIMD[dtype, width]) capturing thin -> SIMD[dtype, width]]): Optional compute epilogue lambda, for example a static scale (defaults to None).
pdl_level (PDLLevel): Programmatic dependent launch level for the dispatched kernel (defaults to PDLLevel()).
has_epilogue_tensor (Bool): Whether an epilogue tensor is supplied for the TMA epilogue load path (defaults to False).
epilogue_is_1d (Bool): Whether the epilogue tensor is treated as 1D rather than row-major 2D (defaults to False).

Returns:

Int
