I haven't used it. I've been wanting to try. I've heard it works ok in Linux but I've heard of problems with it under Solaris. Now that I understand what the OP is trying to do, I think POSH is overkill, and just using pipes or sockets is fine. If he really wants to use shared memory, hmmm, there used to be an shm module at http://mambo.peabody.jhu.edu/omr/omi/source/shm_source/shm.html but that site now hangs (and it's not on archive.org), and Python's built-in mmap module doesn't support any type of locks. I downloaded the above shm module quite a while ago, so if I can find it I might upload it to my own site. It was a straightforward interface to the Sys V shm calls (also *nix-only, I guess). I guess he also could use mmap with no locks, but with separate memory regions for reading and writing in each subprocess, using polling loops. I sort of remember Apache's mod_mmap doing something like that if it has to. To really go off the deep end, there are a few different MPI libraries with Python interfaces. > I looked at the paper... well, not all 200+ pages, but I checked > how they handle a couple parts that I thought hard and they > seem to have good ideas. 200 pages?? The paper I read was fairly short, and I looked at the code (not too carefully) and it seemed fairly straightforward. Maybe I missed something, or am not remembering; it's been a while. > I didn't find the SourceForge project > so promising.

Yeah, using it for anything serious would involve being willing to fix problems with it as they came up. But I think the delicate parts of it are parts that aren't that important, so I'd just avoid using those. -- http://mail.python.org/mailman/listinfo/python-list
