Posix, SVR4 and IRIX IPC funcionality is all available. Start with insight -
Topics in IRIX Programming - Interprocess Communication and it will give you
more details than I can here.

Consider also that some software is not installed by default (eoe.sw.svr4net,
for example).

Also consider using pfDataPools. This allows unrelated processes to
communicate through shared memory. The caveat is that you have to link
your unrelated program to Performer.
