Challenge Problems
Push your limits with challenges.
Question 1
Consider a system with three tasks: Task 1 with an absolute deadline of 50 ms, remaining execution time of 20 ms, Task 2 with a deadline of 40 ms and execution time of 10 ms, and Task 3 with a deadline of 30 ms and execution time of 5 ms. Calculate the laxity for each task if the current time is 25 ms.
💡 Hint: Use the laxity formula for each task based on the current time.
Question 2
Discuss the implications of a task with negative laxity in LLF scheduling. What action should the system take if it finds a task with negative laxity?
💡 Hint: Think about the scheduling actions that ensure timely task execution.
