Windows Processor Groups

Hi,

Does anyone have experience with Windows Processor Groups?  I'm pondering getting a 64-core hyperthreaded (128 threads) machine to speed compute-bound OpenMP program which will happily use all the threads it can get its little hands on.  Are there ways to get more than 64 threads assigned to a process in WIn 7 or 10?  Are there any impediments to just running two instances of the code, one each in each of the processor groups?  Memory contention issues?

thanks,

Bruce
