Group Size = 8 plus Core parking won't work. Just test it, if you make groupsize = 8 and parking min cores 50% then half of the threads of each CCX will be stopped until some workload will require additional threads from each CCX. 4 threads from the first CCX will be unparked , and 4 threads from the second CCX will be unparked at the same time. So groupsize is not the way to go. Sorry for my bad english.
