dyson@iquest.net said: :- The main problem that I was trying to solve was the silly bouncing. But it can only be called "silly" if the scheduling latency introduced by bouncing to another CPU is greater than that introduced by waiting to schedule the process on the "current" CPU, right? Have you actually measured that? It seems reasonable to me that a scheduler might cause processes to periodically bounce from CPU to CPU, and still be optimizing "global" latency...depending on what the processes are doing. Or are you using some other measure of scheduling performance than latency? --------------------------------------------------------------------- Robert Withrow, R.W.
