(0)Real Time Scheduling

• Many real time systems run a known collection of tasks. The execution time of the tasks is frequently known ahead of time.
• Tasks have deadlines by which they must complete.
• If a task that runs for 3 time units must be done at time 10, it must start by time 7.
• If two tasks that runs for 3 time units each must be done at time 10, one must start by time 4.
