Question: what's the relatonship between CPU load and number of CPUs used

[hmf]

I am trying figure out what the relationship is between the CPU load generated and the number of CPUs and threads used. Am I correct in saying that the load is system wide and that FakeLoad will use more threads/CPUs to ensure that that much system usage is reached?

I would also like to confirm that composite FakeLoad do not have any mapping to the use of CPUs or any other resources (i.e: they are not execute in parallel).

TIA
