how to find out CPU utilization on multi-procesors Linux?

I am working on a Linux box which has 4 processors, I know using top can give the inoframtion about the load of a process uisng the CPU.

But is there any way I can find out which applicaiton/process is on which CPU with information on load (say %)?

I am trying to find out if there is any way I can put the heavy load application on once CPU, and then put all the others on the rest of CPUs. Is this a good idea? Any other good approaches other than this one?

Thanks for the help.

top will tell you this. Hit the "1" key to have it display CPU for each of the processors, then hit "f" to display a list of the available fields, and "j" to show the last used CPU.

Since applications are load-balanced across the CPUs, it's tough to load up only one.

using the top command and see what the processor is used for my applicaiton/process;

but I got confused by the column %CPU, does the number 100 means the CPU is doing some computaiton 100% of time for the application/process, or it just means that % of time is assigned to that application/proceses?

Hugh FraserConsultantCommented:
The %CPU reflects the percentage of CPU used by the specific process during the last sample period. So 100% would indicate that the process consumed 100% of the available CPU. The total of CPU columns from all the processes should generally add up to about the same as the overall %us (user mode) value at the top of the display.
