    CUDA Dispatcher object. When configured and called, the dispatcher will
    specialize itself for the given arguments (if no suitable specialized
    version already exists) & compute capability, and launch on the device
    associated with the current context.

    Dispatcher objects are not to be constructed by the user, but instead are
    created using the :func:`numba.cuda.jit` decorator.

        This assumes that:

        - the kernel maps the Global Thread ID ``cuda.grid(1)`` to tasks on a
          1-1 basis.
        - the kernel checks that the Global Thread ID is upper-bounded by
          ``ntasks``, and does nothing if it is not.

        :param ntasks: The number of tasks.
        :param tpb: The size of a block. An appropriate value is chosen if this
                    parameter is not supplied.
        :param stream: The stream on which the configured dispatcher will be
                       launched.
        :param sharedmem: The number of bytes of dynamic shared memory required
                          by the kernel.

        A list of objects that must have a `prepare_args` function. When a
        specialized kernel is called, each argument will be passed through
        to the `prepare_args` (from the last object in this list to the
        first). The arguments to `prepare_args` are:

        - `ty` the numba type of the argument
        - `val` the argument value itself
        - `stream` the CUDA stream used for the current call to the kernel
        - `retr` a list of zero-arg functions that you may want to append
          post-call cleanup work to.

        The `prepare_args` function must return a tuple `(ty, val)`, which
        will be passed in turn to the next right-most `extension`. After all
        the extensions have been called, the resulting `(ty, val)` will be
        passed into Numba's default argument marshalling logic.
