The first line of output from top shows the following information. The C
column indicates that it's a multi-proc system and which CPU a given process
is currently running on.

PID USERNAME      PRI NICE  SIZE    RES STATE  C   TIME   WCPU    CPU
COMMAND

You can also "type /var/run/dmesg.boot" and it will show you the CPU
information as well.
