Backend.AI Kernel Runner
========================
A common base runner for various programming languages.
It manages an internal task queue so that multiple command/code execution requests
are processed in the FIFO order, without garbling the console output.
How to write a new computation kernel
-------------------------------------
Inherit ``ai.backend.kernel.BaseRunner`` and implement the following methods:
* ``async def init_with_loop(self)``
- Called after the asyncio event loop becomes available.
- Mostly just ``pass``.
- If your kernel supports interactive user input, then put set
``self.user_input_queue`` as an ``asyncio.Queue`` object. It's your job
to utilize the queue object for waiting for the user input. (See
``handle_input()`` method in ``ai/backend/kernel/python/inproc.py`` for
reference) If it's not set, then any attempts for getting interactive user
input will simply return ``"<user-input is unsupported>"``.
* ``async def build_heuristic(self)``
- *(Batch mode)* Write a heuristic code to find some build script or run a
good-enough build command for your language/runtime.
- *(Blocking)* You don't have to worry about overlapped execution since the
base runner will take care of it.
* ``async def execute_heuristic(self)``
- *(Batch mode)* Write a heuristic code to find the main program.
- *(Blocking)* You don't have to worry about overlapped execution since the
base runner will take care of it.
* ``async def query(self, code_text)``
- *(Query mode)* Directly run the given code snippet. Depending on the language/runtime,
you may need to create a temporary file and execute an external program.
- *(Blocking)* You don't have to worry about overlapped execution since the
base runner will take care of it.
* ``async def complete(self, data)``
- *(Query mode)* Take a dict data that includes the current line of code where
the user is typing and return a list of strings that can auto-complete it.
- *(Non-blocking)* You should implement this method to run asynchronously with
ongoing code execution.
* ``async def interrupt(self)``
- *(Query mode)* Send an interruption signal to the running program. The implementation
is up to you. The Python runner currently spawns a thread for in-process
query-mode execution and use a ctypes hack to throw KeyboardInterrupt
exception into it.
- *(Non-blocking)* You should implement this method to run asynchronously with
ongoing code execution.
NOTE: Existing codes are good referecnes!
How to use in your Backend.AI computation kernels
-------------------------------------------------
Install this package using pip via a ``RUN`` instruction in Dockerfile.
Then, set the ``CMD`` instruction like below:
.. code-block:: dockerfile
CMD ["/home/backend.ai/jail", "-policy", "/home/backend.ai/policy.yml", \
"/usr/local/bin/python", "-m", "ai.backend.kernel", "<language>"]
where ``<language>`` should be one of the supported language names defined in
``lang_map`` variable in ``ai/backend/kernel/__main__.py`` file.
