11 Consider the following three independent periodic tasks: T₁ = (4, 1), T₂ = (5, 2), T3 = (10, 2). T₁ and T3 are preemptable, but T₂ is not. (a) Construct the RM schedule of the system in the first 20 units of time. (b) Construct the EDF schedule of the system in the first 20 units of time.
An optimum solution only applies to a mathematical model that represents the issue
If a sporadic implicit deadline task set is schedulable under RM, will it be schedulable under RM after enlarging one of the deadlines (now it becomes an arbitrary deadline task set)? Note that we are still following the original RM priority order (not DM). What if we follow DM order?
In the model in Example 15.5, suppose bonuses and penalties are incurred for earliness or lateness. Specifically, suppose a bonus of $2000 is received if the project is completed within 60 days, an extra bonus of $1000 is received if the project is completed within 58 days, and a penalty of $1000 is incurred for every full day past a project completion of 64 days. (For example, if the project is completed in 66.7 days, the penalty is $2000—two full days late.) Modify the model appropriately, and then run the simulation to find the distribution of the net monetary outcome (negative if a penalty, positive if a bonus). What is the expected value of this net amount? What is the probability of a $3000 total bonus? What is the probability of a penalty of at least $4000?

Consider the following task set. Task T T1 1 3 T2 2 4 T3 1 6 Using a timeline, show how a cyclic executive can be constructed for the task set. You may assume that the tasks can be arbitrarily “split up", but only at integer execution-time points. Thus, cach split-part of a task will have an integer execution time.
