Abstract
A thread scheduler may be used in a chip multiprocessor or symmetric multiprocessor system to schedule threads to processors. The scheduler may determine the bandwidth utilization of the two threads in combination and whether that utilization exceeds the threshold value. If so, the threads may be scheduled on different processor clusters that do not have the same paths between the common memory and the processors. If not, then the threads may be allocated on the same processor cluster that shares cache among processors.
