I want to schedule a periodic process. I have: Thread---------Exec.time-----------period-time A-----------------2 ---------------------- 5 B-----------------2 ----------------------6 C-----------------3 ----------------------15 D-----------------1---------------------- 30
Can we schedule the system whit Earliest deadline first scheduling (EDF).? Can we schedule the system whit Rate-Monotonic scheduling(RMS).? ------------------------------------------------------------------------------------- I Think: whit EDF: 2/5 + 2/6 + 3/15 + 1/30=0,9666….. The theoretical limit for 4 processes is 100% and so the system is schedulable
------------------------------------------------------------------------------------- I Think: whit RMS: 2/5 + 2/6 + 3/15 + 1/30=0,9666…..
The theoretical limit for 4 processes will be: U=4(2^(1/4) -1)=0,7568 If 0,9666> 0,7568... the system is not schedulable! ------------------------------------------------------------------------------------ How can I show these two systems (whit graph)
