This stops the local agent from accepting outstanding requests, and shuts down the RPC framework by terminating all RPC threads. If ``graceful=True``, this will block until all local and remote RPC processes reach this method and wait for all outstanding work to complete. Otherwise, if ``graceful=False``, this is a local shutdown, and it does not wait for other RPC processes to reach this method. .. warning:: For :class:`~torch.futures.Future` objects returned by :meth:`~torch.distributed.rpc.rpc_async`, ``future.wait()`` should not be called after ``shutdown()``. Args: graceful (bool): Whether to do a graceful shutdown or not. If True, this will 1) wait until there is no pending system messages for ``UserRRefs`` and delete them; 2) block until all local and remote RPC processes have reached this method and wait for all outstanding work to complete. Example:: Make sure that ``MASTER_ADDR`` and ``MASTER_PORT`` are set properly on both workers. Refer to :meth:`~torch.distributed.init_process_group` API for more details.

Worker ``to`` will be the owner of the returned :class:`~torch.distributed.rpc.RRef`, and the worker calling ``remote`` is a user. The owner manages the global reference count of its :class:`~torch.distributed.rpc.RRef`, and the owner :class:`~torch.distributed.rpc.RRef` is only destructed when globally there are no living references to it. Args: to (str or WorkerInfo or int): name/rank/``WorkerInfo`` of the destination worker. func (Callable): a callable function, such as Python callables, builtin operators (e.g. :meth:`~torch.add`) and annotated TorchScript functions. args (tuple): the argument tuple for the ``func`` invocation. kwargs (dict): is a dictionary of keyword arguments for the ``func`` invocation. timeout (float, optional): timeout in seconds for this remote call. If the creation of this :class:`~torch.distributed.rpc.RRef` on worker ``to`` is not successfully processed on this worker within this timeout, then the next time there is an attempt to use the RRef (such as ``to_here()``), a timeout will be raised indicating this failure. A value of 0 indicates an infinite timeout, i.e. a timeout error will never be raised. If not provided, the default value set during initialization or with ``_set_rpc_timeout`` is used. Returns: A user :class:`~torch.distributed.rpc.RRef` instance to the result value. Use the blocking API :meth:`torch.distributed.rpc.RRef.to_here` to retrieve the result value locally. .. warning :: The ``remote`` API does not copy storages of argument tensors until sending them over the wire, which could be done by a different thread depending on the RPC backend type. The caller should make sure that the contents of those tensors stay intact until the returned RRef is confirmed by the owner, which can be checked using the :meth:`torch.distributed.rpc.RRef.confirmed_by_owner` API. .. warning :: Errors such as timeouts for the ``remote`` API are handled on a best-effort basis. This means that when remote calls initiated by ``remote`` fail, such as with a timeout error, we take a best-effort approach to error handling. This means that errors are handled and set on the resulting RRef on an asynchronous basis. If the RRef has not been used by the application before this handling (such as ``to_here`` or fork call), then future uses of the ``RRef`` will appropriately raise errors. However, it is possible that the user application will use the ``RRef`` before the errors are handled. In this case, errors may not be raised as they have not yet been handled. Example:: Make sure that ``MASTER_ADDR`` and ``MASTER_PORT`` are set properly on both workers. Refer to :meth:`~torch.distributed.init_process_group` API for more details.
