A priority-based preemptive scheduling policy, job with earliest (absolute) deadline has highest priority, does not require knowledge of execution times

what happens when two tasks has the same deadline? is the one executing gets interrupted or will it just run to finish before it executes the other task?

I think there will be no preemption in EDF. Tasks are chosen in the FCFS manner

You have to calculate the summation of every process's CPU burst time/ period time. if the result is less equal than 1, then it's schedulable.

Sir may i know why at the point of 5 to 7 t3 started becuase we have t2 higher priority and t2 shuld start before t3 right can you please correct me if i am wrong
@saileshpant1350

At point 5, deadline of T2 is 9 and that of T3 is 8 and hence T3 has highest priority.

DM working on relative deadline and EDF working on Absolute deadline. In DM, you get next deadline by addition with period. Or in EDF you get next deadline by addition with previous deadline.

t3 should come 2 times between 0 -to 10(capacity 2) but you only did 1 t3 again comes at 9-10 interval.
@maheshworry
@maheshworry 4 жыл бұрын
T3 has a capacity of 2 which is fulfilled once it is called at '5'. In the 0-10 period, it is supposed to be called only once. Hence, I don't think there's a problem in the answer of the teacher. P.S. "Capacity" doesn't mean the number of times it is called; it just means the amount of time it takes to get executed!

No, at time 5, T3 has highest priority because its deadline (8) is earlier than T2's next deadline (9).
