Unfortunately running 2 separate instances (4 threads each) of PARSEC
isn't possible as it results in different memory working sets than a
single 8 thread instance. We chose to just use
the system-wide command (so it wouldn't panic) on a single memory
controller and average our results across multiple runs looking at the
different controllers.
