Normally the OS scheduler distributes applications on the available CPUs in the way it thinks is most reasonable. Which means applications is not strictly limited to one CPU but bounces around a bit between the CPUs. However, networks cards and other hardware gets quite tightly coupled to one of the CPUs, and applications dependent on results of that tend to get scheduled onto the same CPU simply because they are waiting on the results.. Usually there is system tools to manually re-balance the decisions if you don't agree with the scheduler for some reason. On linux this includes irqbalance, taskset, and a few other tools. Other OS:es uses other tools.. Likewise there is no uniform standard to inspect which processes gets scheduled on which CPU. On Linux you can get quite detalied statistics on the CPU usage and a lot of other things from oprofile if you insist on it, but it's not a very easy tool to work with (it's a low level general system profiler, not just for displaying CPU usage..)
