Currently looking at the realtime Linux scheduler code...oh man! it has changed quite a bit from the last time I had seen it. For realtime tasks, the logic behind pushing and pulling of tasks looks pretty impressive..the cpu priority management by Gregory Haskins is nice, but overall, rt task load balancing is not yet scalable...it is O(n). So as the number of processors increase, the latencies in scheduling a particular rt task would increase linearly...but this is a cool piece of code to work with ;-) Having fun!!
