Suppose I run /bin/init with a certain CPU affinity (not covering all CPUs) and then run my own specific service on the remaining CPUs, how would this differ from your approach? >>From what I quickly gathered, you are running parts of the kernel space on the second CPU set, or is that too simple a statement? Looks like a very fresh approach, nice project! Regards, -- Leon
