When you are using SMP (Symmetric MultiProcessing) you might want to override the kernel’s process scheduling and bind a certain process to a specific CPU(s). CPU affinity is nothing but a scheduler property that “bonds” a process to a given set of CPUs on the SMP system.

For example, application such as Oracle licensed per CPU. You can bound Oracle to specific CPU to avoid license problem. This useful on large server having 4 or 8 CPUS. . With the help of Linux scheduler utilities you can set up processor affinity for a certain task or process. The scheduler attempts to keep processes on the same CPU as long as practical for performance reasons. Therefore, forcing a specific CPU affinity is useful in certain applications.
