Question

Alert dont submit AI generated answer.

1. The list - processing algorithm requires a priority list to break scheduling ties. How many possible priority lists are there for this job? Where the
questions that follow ask for a processor's schedule, enter a list of tasks in the order scheduled, separated by spaces. If idle time follows a task,
indicate it as a unit - less number. For example, "T3 5 T4 T1" would indicate that after T3 is completed there are 5 units of idle time on the schedule
followed by T4 and then T1. 2. Use the list - processing algorithm to schedule the job on two processors. Use the following priority list: T1, T2, T3,
T4, T5, T6, T7, T8. List the tasks, including any idle time, on the first processor. 3. List the tasks, including any idle time, on the second processor.
4. How much time does the schedule require? Only enter the number, in minutes. 5. Use the list - processing algorithm to schedule the job on two
processors. Use the following priority list: T4, T1, T7, T5, T2, T3, T6, T8. List the tasks, including any idle time, on the first processor. 6. List the
tasks, including any idle time, on the second processor. 7. How much time does the schedule require? Only enter the number, in minutes.
