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.

pbind is doing that, at least on Solaris. There is also psrset.

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.
