"The :class:`InterpreterPoolExecutor` class uses a pool of interpreters to "
"execute calls asynchronously.  It is a :class:`ThreadPoolExecutor` subclass, "
"which means each worker is running in its own thread. The difference here is "
"that each worker has its own interpreter, and runs each task using that "
"interpreter."
#: library/concurrent.futures.rst:248
"The biggest benefit to using interpreters instead of only threads is true "
"multi-core parallelism.  Each interpreter has its own :term:`Global "
"Interpreter Lock <global interpreter lock>`, so code running in one "
"interpreter can run on one CPU core, while code in another interpreter runs "
"unblocked on a different core."
#: library/concurrent.futures.rst:254
"The tradeoff is that writing concurrent code for use with multiple "
"interpreters can take extra effort.  However, this is because it forces you "
"to be deliberate about how and when interpreters interact, and to be "
"explicit about what data is shared between interpreters. This results in "
"several benefits that help balance the extra effort, including true multi-"
"core parallelism,  For example, code written this way can make it easier to "
"reason about concurrency.  Another major benefit is that you don't have to "
"deal with several of the big pain points of using threads, like race "
"conditions."
#: library/concurrent.futures.rst:264
"Each worker's interpreter is isolated from all the other interpreters. "
"\"Isolated\" means each interpreter has its own runtime state and operates "
"completely independently.  For example, if you redirect :data:`sys.stdout` "
"in one interpreter, it will not be automatically redirected to any other "
"interpreter.  If you import a module in one interpreter, it is not "
"automatically imported in any other.  You would need to import the module "
"separately in interpreter where you need it.  In fact, each module imported "
"in an interpreter is a completely separate object from the same module in a "
"different interpreter, including :mod:`sys`, :mod:`builtins`, and even "
"``__main__``."
#: library/concurrent.futures.rst:276
"Isolation means a mutable object, or other data, cannot be used by more than "
"one interpreter at the same time.  That effectively means interpreters "
"cannot actually share such objects or data.  Instead, each interpreter must "
"have its own copy, and you will have to synchronize any changes between the "
"copies manually.  Immutable objects and data, like the builtin singletons, "
"strings, and tuples of immutable objects, don't have these limitations."
#: library/concurrent.futures.rst:284
"Communicating and synchronizing between interpreters is most effectively "
"done using dedicated tools, like those proposed in :pep:`734`.  One less "
"efficient alternative is to serialize with :mod:`pickle` and then send the "
"bytes over a shared :mod:`socket <socket>` or :func:`pipe <os.pipe>`."
#: library/concurrent.futures.rst:292
"A :class:`ThreadPoolExecutor` subclass that executes calls asynchronously "
"using a pool of at most *max_workers* threads.  Each thread runs tasks in "
"its own interpreter.  The worker interpreters are isolated from each other, "
"which means each has its own runtime state and that they can't share any "
"mutable objects or other data.  Each interpreter has its own :term:`Global "
"Interpreter Lock <global interpreter lock>`, which means code run with this "
"executor has true multi-core parallelism."
#: library/concurrent.futures.rst:300
"The optional *initializer* and *initargs* arguments have the same meaning as "
"for :class:`!ThreadPoolExecutor`: the initializer is run when each worker is "
"created, though in this case it is run in the worker's interpreter.  The "
"executor serializes the *initializer* and *initargs* using :mod:`pickle` "
"when sending them to the worker's interpreter."
#: library/concurrent.futures.rst:308
"The executor may replace uncaught exceptions from *initializer* "
"with :class:`~concurrent.futures.interpreter.ExecutionFailed`."
#: library/concurrent.futures.rst:311
msgid "Other caveats from parent :class:`ThreadPoolExecutor` apply here."
#: library/concurrent.futures.rst:313
":meth:`~Executor.submit` and :meth:`~Executor.map` work like normal, except "
"the worker serializes the callable and arguments using :mod:`pickle` when "
"sending them to its interpreter.  The worker likewise serializes the return "
"value when sending it back."
#: library/concurrent.futures.rst:318
"When a worker's current task raises an uncaught exception, the worker always "
"tries to preserve the exception as-is.  If that is successful then it also "
"sets the ``__cause__`` to a "
"corresponding :class:`~concurrent.futures.interpreter.ExecutionFailed` "
"instance, which contains a summary of the original exception. In the "
"uncommon case that the worker is not able to preserve the original as-is "
"then it directly preserves the "
"corresponding :class:`~concurrent.futures.interpreter.ExecutionFailed` "
"instance instead."

"module, which allows it to side-step the :term:`Global Interpreter Lock "
"<global interpreter lock>` but also means that only picklable objects can be "
"executed and returned."
