As far as I know, on SMP systems, when a process, say A, send a message to process B, OS first put the message in a memory area known by both processes, then B take it from the area. Is the ipc mechanism on NUMA systems the same? Does the ipc has any optimal support for NUMA? Last edited by rainman1985_2010; 06-05-2011 at 10:45 PM.
