Task Scheduling and Dependencies

This video tutorial covers the list processing algorithm for scheduling tasks. It begins with an introduction to the algorithm, followed by a detailed explanation of its steps. The tutorial then demonstrates how to create a diagraph from a priority list and use it to schedule tasks using two processors. The process involves identifying ready tasks, assigning them to processors, and marking tasks as in progress or complete. The tutorial concludes with a completed schedule and a discussion of idle time.

What is the first step in the list processing algorithm for scheduling?

• Mark tasks as complete

• Assign tasks to processors

• Circle all tasks that are ready

• Create a digraph

What is the purpose of creating a digraph from a priority list?

• To visualize task dependencies

• To calculate total project time

• To assign tasks to processors

• To mark tasks as complete

What is the significance of the arrows in the digraph?

• They mark task completion

• They represent processor assignments

• They show task dependencies

• They indicate task duration

Which tasks are assigned to processors first?

• Tasks with the longest duration

• Tasks with no prerequisites

• Tasks with the highest priority

• Tasks with the shortest duration

Which task becomes ready after Task 2 is completed?

• Task 3

• Task 4

• Task 5

• Task 6

What happens when a task is marked as complete?

• It is removed from the digraph

• The project ends

• It is assigned to a processor

• New tasks may become ready

What is the prerequisite for Task 9 to become ready?

• Completion of Task 4

• Completion of Tasks 5 and 6

• Completion of Task 8

• Completion of Task 7

Which task is assigned to Processor 1 after Task 6 is completed?

• Task 7

• Task 8

• Task 5

• Task 9

How is idle time for a processor identified in the schedule?

• By a note in the schedule

• By a special symbol

• By a different color

• By a gap in the task list

What is the total project time with 2 processors?

• 28 hours

• 31 hours

• 26 hours

• 24 hours
