Hello dear all

I am trying to change parallel fraction ratio of a a fixed program workload , then it runs on Core i7 quad core to calculate the change in CPU performance,

when I increased the parallel ratio the performance counter unhalted_clock decreasing in high parallel ratio and the highest value of the same counter when I have full sequential execution in single core?

Why this happen, and where the additional workload come from.

Thank you
