[opensuse-programming] Has anyone used POSIX message queues?
I'm thinking about using posix message queues in a new design, and I was just wondering if anyone had anything good or bad to say about the concept? /Per Jessen, Zürich --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-programming+help@opensuse.org

Ignore that - I need inter-system message queues, not inter-process. I have a process on system A that needs to have guaranteed delivery of messages to system B. Any suggestions? /Per Jessen, Zürich --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-programming+help@opensuse.org

Uh, forgot to say it needs to be something I can use from C and it should scale well. /Per Jessen, Zürich --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-programming+help@opensuse.org

Been a while since I worked with this stuff, but it made me curious if a clustering solution would be what your looking for? LinuxHA has a guaranteed delivery messaging protocol around the cluster. And OpenSSI extends the interprocess methods to work even if the processes are on different cluster members. As a guess the LinuxHA method may be best and you can use its comm protocol without actually having any clustered services. (or you can if you need them.) Not sure how scalable you need. I think LinuxHA caps out at 8 nodes.

Possibly, I've looked at DRBD and MPI, but dismissed both in round one. DRBD for not having the right kind of master-slave concept, MPI for being overkill.

I'll have to check that out. It sounds exactly like that I'm after. I've bascially got several processes, each on their own server, that need to pass messages to a central server or cluster (depending on load). The delivery has to be guaranteed, that's all. In many ways it looks very much like syslog-ng sending log lines to a central log-server.
And OpenSSI extends the interprocess methods to work even if the processes are on different cluster members.

I'll need up towards 100 nodes, but it still sounds like it's worth a look. Thanks Greg. /Per Jessen, Zürich --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-programming+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-programming+help@opensuse.org
