how to assign CPU resource to a certain process(RHEL 5.5 client with workstation)

Hi guru,

How to assign CPU and memory resource to a certain process?
How to assign CPU and memory resource to a certain user?
Let's assume the software is no limit for resource usage.

Below is a description of my situation.
dual 6 core, 32G memory, RHEL5.5 client with workstation option.

I run a big computation (say process1). However, I found from KDE system guard the CPU and memory are not loaded as expected. below are numbers.

user% system%
process1 100 0.00

and CPU idle 90%, memory free 97%

Probably single threaded - in which case it wil never use more than 1 core. You can't do anything to give it more CPU - except use "bigger" cores.
See if you have a multi-threaded option.

As for isolating workloads, I find cgroups much more usabale - and it accomodates forked processes.

thanks a lot for reply.
