The system will automatically schedule work in available processors; there is no user action required or desirable. Manually scheduling work on individual processors only applies to non-symmetrical systems - where different resources are available to each CPU.

This Linux Journal article discusses Linux processor affinity, and provides the source code to a simple tool that will let you bind a process to a given CPU. Unless you have a really good reason to do this, you are much more likely to hinder the system than to help it.

If the requirement is to guarantee CPU resource to a set of privilege processes, a better approach is to use a fair share scheduler http://en.wikipedia.org/wiki/Fair-share_scheduling , Solaris Resource Manager implement that.
