.. function:: warp._src.lang.tile_argmax(a: Tile[Scalar,tuple[int, ...]]) -> Tile[Int,tuple[Literal[1]]]

   .. hlist::
      :columns: 8

      * Kernel

   Cooperatively compute the index of the maximum element in the tile using all threads in the block.
   
   :param a: The tile to compute the argmax from
   
   :returns: A single-element tile holding the index of the maximum value.
