CPU utilization

[garyellis]

I have a quad core processor. Is there a way to tell which process is running on which core?

When I use task manager, I see 4 boxes under performance...The first is always the highest and the other 3 barely move...

I am recording an HD show in Sage and running comskip while recording and using videoredo to edit a different HD show. I would like to see if the system is spreading these tasks out among the different cores or how the CPU utilization works.

Thanks,

Gary Ellis

What is your OS? Generally speaking, OS will spread the work across CPUs by default (as long as they are multi-threaded).

If you are running Vista you can get a gadget that shows the utilization of all of your CPUs - I use one and it shows how my measly 2 cores are doing!

I'm using windows XP SP2....

I assume it is spreading the work across the CPU's, but task manager is not showing it that way...

So, wondering if there is a tool or something that can give me more information..

The task manager (CTRL+ALT+DEL) will show the load per CPU.

You could always try Process Explorer. I think there is a way to see which Proc is being used by which process:

I use something called "processwatch" to monitor and control CPU prioritys, and I know that it has the ability to set certain processes affinity for different CPU's, that may be useful to you.
