If the code is a nice tight loop that correctly/full uses the cpu with

Hi,
Just a quick question. To determine how many cpu's/cores/channels
the kernel is configured to support, do I need to look at the kernel
source to determine if all of the cores I have are capable of being
used, or is there something else available to tell me without going to
the source?
