For this assignment you will write a program (the controller) that will synchronize the actions of other compute intensive processes (compute processes). Pipes will be used to cause this synchronization. The synchronization will be used to obtain an estimate of the elapsed time required for the compute intensive processes to perform their computations. This measurement is to be made by the controller. This measurement cannot be started until the compute processes have initialized and have reported that they are ready. The controller then tells the compute processes to compute.
