Consider the following set of tasks in a real-time system:

Tasks	Release time	Execution time	Absolute deadline
T 1	0	4	40
T 2	3	9	20
T 3	7	5	30
T 4	11	8	20
T5	14	2	40

Perform EDF scheduling on these task set.

Discuss different common combinations of blocking & non-blocking for both sender and receiver while message passing.
