Limit Process's CPU utilization

Hello

How to limit the CPU utilization for a process to a certain value or percentage so in any case this process would never exceed that limit?

thanks

If you want to limit the total amount of CPU time used, the shell can do that; see ulimit (or limit if using the C shell). See man page for ulimit or csh.

For a percentage of time, you might have to use class scheduling. See the class_scheduling man page.

Another possibility: if you have a multi-CPU system, you can restrict the process to a single processor or a set of processors, which effectively limits its share of the total available CPU power. See the man page for runon.
