Nonstop Process Pair

A Nonstop Process Pair refers to
       - a primary process residing in a particular CPU
       - and a designated backup CPU residing in another CPU.

They share the same process name and but have a difference Process ID(CPU:PIN).

They can be configured to be amneisa backup processes(i.e they know nothing about the state of other process) or

they communicate with each Other to preserve state using checkpoints.
