Zeromq (suggested by someone) is an option since it's pretty fast for
most purposes, but I don't think it uses shared memory.
Interesting question. The documentation says:
http://api.zeromq.org/2-1:zmq-ipc
The inter-process transport is currently only implemented on operating
systems that provide UNIX domain sockets.
(OFF: Would it be possible to add local IPC support for Windows using
mmap()? I have seen others doing it.)
At least, it is functional on Windows, and it excels on Linux. I just
need to make transports configureable. Good enough for me.
The closest
thing I can think of to what you're asking is MPI, intended for
scientific computation. I don't know of general purpose IPC that uses
it though I've thought it would be interesting. There are also some
shared memory modules around, including POSH for shared objects, but
they don't switch between memory and sockets AFAIK.
Based on your description, maybe what you really want is Erlang, or
something like it for Python. There would be more stuff to do than just
supply an IPC library.
Yes, although I would really like to do this job in Python. I'm going to
make some tests with zeromq. If the speed is good for local
inter-process communication, then I'll give it a try.
Thanks,
Laszlo
