"# cat /proc/cpuinfo" will reveal how many _cores_ are out there (e.g.
if you have a single Xeon, you'll see two CPUs).

If you're running the SMP kernel, all available processors will be used.
"top" will reveal the activity level of each processor.

Unless you code for specific "CPU affinity", the system will assign a
processor to use for each thread of concurrency.  You can control what
task goes where by use of the "taskset" command.

See "man top", "man taskset" and the text file
"/usr/share/doc/kernel-doc-*/Documentation/filesystems/proc.txt"
