 In this pattern, parallel processing is performed using a system consisting of a master and some number of workers, where a master divides the work among the workers, gets the result back from them and assimilates all the results to give final result. The only communication is between the master and the worker - none of the workers communicate among one another and the user only communicates with the master to get the required job done. The master has to maintain a record of how the divided data has been distributed, how many workers have finished their work and returned a result, and the results themselves to be able to aggregate the data correctly.
