Has anyone every tried wrapping the CPython lib into a daemon with an
RPC mechanism in order to move the GIL out of the process? I have
multiple audio threads, each of which use the python interpreter but
don't have to interact with each other and can might as well use a
separate interpreter handled by a daemon with libpython linked in.
I've never used a C xmlrpc lib before and would probably need to set
up some shared memory to get it to work. Can anyone suggest a library
out there that would at do that sort of thing, maybe with some
cross-platform process management?
I imagine this is how the multiprocessing module works.
Yes, it does seem you need multiprocessing. That would take advantage
of multiple cores and the GIL wouldn't bother you at all. Take a look
at
http://docs.python.org/library/multiprocessing.html
For what you describe (separate tasks running concurrently without
communicating) the multiprocessing module would be ideal.
The problem is that the OP has a embedded application running threads.
multiprocssing doesn't help there.
