a) What is the domain and range of each process? P₁ P2 P3 P4 Process Domain M₁+5/ 2M3 My+7 ама a) Is the system of processes determinate? Why or why Not? Yes, it's determinate because Range M3X M3/+Ms Маха M3-1; M2+1 M412 the processes are Order and allocate in sequential to proper memory cell No. b) Are all pairs of processes mutually non-interfering? Why or why Not? No, they aren't because the pairs of processes handle various memory. Show the interfere cells c) What modifications are needed to guarantee that the system will be determinate for all interpretations? The memory allocated cells need to be in order per process Assume a system of 4 processes P = {P₁, P2, P3, P4} and 5 memory cells M = {M1, M2, M3, M4, M5}. All memory cells are initialed to 0 before any processes are started. The processes implement the following instructions: Process Instructions M₁ +1-M5 M3 P1 P2 2M3 ⇒ M2 P3 P4 |2M2 ⇒ M4 => M47 M3; M3 − 1 ⇒ M2 (Sequentially) You are also given the following precedence relation: ⇒: {(P2, P4), (P2, P3), (P1, P2), (P1, P₁)}
