Can we run multiprocessing Pool in GAE?

Is it possible to run multiprocessing Pool in gae?

If yes, how come my code runs fine in my local machine but pops out the following err msg with django remote api:

File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/multiprocessing/pool.py", line 148, in map
    return self.map_async(func, iterable, chunksize).get()   
File "/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/multiprocessing/pool.py", l开发者_运维技巧ine 422, in get
    raise self._value TypeError: __init__() keywords must be strings

You won't be able to run multiprocessing on the production servers, but if you are using the remote_api, then you can run your script locally (with multiprocessing) and have each Pool process use communicate with the production server via remote_api calls.

If you need multiprocess style actions actually in server-side code, then the Mapper API is perfect for this task.
