Thread Design Techniques

A) Pipeline
Task is divided into multiple sub tasks and each thread is responsible for doing one subtask. Job is passed from one thread to other till it reaches the final state.

B) Master/Servant
Master thread does accept the work and delegates work to its servants. Servants are created on the fly by the master when a work arrives to the master. After finishing the job servants go away. For next work, master creates new servants.

C) Thread Pool
Master thread does accept the work and delegates work to predefined set of servants, called thread pool. This is usually accomplished by using a queuing mechanism in between. Master adds request to the queue and all the threads in the pool removes the request from the queue and handles it iteratively.
