I recently noticed while crunching some CFD numbers in Matlab that only 50% of my HT processor is being used. I understand basicly that HT is an early imitation of dual core. I assume if i turn off HT i will regain my lost cycles. My question is regarding an invedible upgrade to my rig, which in this day and age most likely means dual core. Does matlab take the same "hit" from dual core? -Thanks!
