I have a recent Macbook Pro. My processor is a: 2.4 GHz (i7-3630QM) quad-core Intel Core i7 Ivy Bridge with 6 MB on-chip L3 cache
I am running some cpu intensive programs, that each use "100%" of the cpu according to Activity monitor. They are very cpu intensive so will use all of the cpu time they can get. I ran 4 of these processes earlier, expecting my system to freeze while they were running and the CPU bar chart in Activity monitor to go to the top, however it says I'm only using 50% of my cpu power and my laptop is happily doing a bunch of other tasks as well!
Can anyone explain this? What does 100% mean in this context, and why are each of my processes only being given half of the time on the cpu when there is 50% of cpu time idle?
Thanks in advance
