1. Consider a system of 9 processes, P = {p1, ..., p9}. Associated with the system are 6 memory cells, M = {M1, ..., M6}. The domain and range for each process is given in the following table: Process pi Domain D(pi) p1 M1, M2 p2 M1 p3 M3, M4 p4 M3, M4 p5 p6 p7 p8 p9 M3 M4 M5 M3, M4 M5, M6 Range R(pi) M3 M5 M1 M5 M4 M4 M5 M2 M6 In addition, you are given the following precedence relation: →= {(P1,P2), (P1, P6), (P2, P3), (P2, P4), (P2,P5),(P3, P6), (P3,P8), (P4,P6), (P4,P7), (P5,P7), (P5,P8), (P6,P8), (P6,P9), (P7,P9), (P8,P9)}
