WebA "schedule" for a set of chains specifies the time at which each task is to begin processing. The schedule must ensure that (a) once a task begins execution it continues until it finishes, (b) no processor executes more than one task at a time, (c) task C[i] must be completed by Pi before task C[i + 1] can begin execution on Web1. To demonstrate the greedy approach, let’s consider the deadlines in the form of a circular structure, as shown below. A given task can fill each slot. Now, let’s start allocated the tasks based on the deadlines. We will start with task 5, having a deadline of 4, and fill it empty slot 3–4.
