1 - [30 pts] Scheduling Algorithms Comparison Assume that we have 5 independent and aperiodic tasks (T1, ... , Ts) and they arrive to the system at times indicated below. Each task will run for the amount of execution time listed and is assigned a priority ranging from 0 (highest) to 10 (lowest), i.e. lower value means higher priority. There are no other tasks scheduled to arrive to the system until T1, ... , Ts complete. Task Arrival Time Execution...

Assume that for this project to be completed, five independent tasks must be completed. These tasks are proceeding in parallel by five different subcontractors. To keep it simple, let's assume that each task takes between 1 and 5 months to complete (uniformly distributed, i.e. equally likely to take any amount of time between 1 and 5 months). So, the mean time to complete each task is 3 months and the probability of any given task taking 3 months or longer...

Question E (8 points): 1. Construct an EDF schedule with HVDF scheduling policy for the following tasks. What is the total value obtained? Ti-(cipi): T (6,24); T2- (4, 8); T3- (4, 8); T4- (4, 12). The values of these tasks are 2, 3, 1, and 2 respectively. Note: Schedule tasks based on deadline as the primary criteria for priority assignment (EDF); if there is a tie in priority, then choose the task with HVDF (High Value Density First) basis. 2....
