Explain why these concurrently executing processes Process P1 Process P3 x-1; z 1: print(y, z); print(x, y): perform the following executions in a sequential consistency. x+1; print(y, z); y1; print(x, z): z+1; print(x, y): Prints: 001011 Signature: 001011 (a) Answer: Process P2 y+1; print(x, z); x-1; ye1; print(x, z); print(y, z); z+1; print(x,y); Prints: 101011 Signature: 101011 (b) y+1; z+1; print(x, y); print(x, z); x-1; print(y, z); Prints: 010111 Signature: 110101 (c) y + 1; x+1; z+1; print(x, z): print(y, z); print(x, y): Prints: 111111 Signature: 111111 (d)
