 * Template parameter D_T_X maps to data type:
 *   - float:       TilingKey 0 (direct fp32 computation)
 *   - half:        TilingKey 1 (direct fp16 computation)
 *   - bfloat16_t:  TilingKey 2 (cast to fp32 -> compute -> cast back)
 *   - int32_t:     TilingKey 3 (cast to fp32 -> compute -> cast back)
 *   - int8_t:      TilingKey 4 (cast to fp16 -> compute -> cast back)
 *
 * Kernel function signature: x, y, workspace, tiling
