Global average activities among all processors are also reported. I am seeing an application's CPU usage being the same with 4 cores and with a single core. Can this number be written in (3^x) - 1 format? http://itivityglobal.com/cpu-usage/cpu-limit-linux.html In a true SMP environment, if 'Irix mode' is Off, top will operate in 'Solaris mode' where a task's cpu usage will be divided by the total number of CPUs.
