18.31 Suppose that MPI_COMM_WORLD consists of the three processes 0.1 and 2, and suppose the following code is executed: ant x, y, z; switch (my_rank) { case @: X = 0; y = 1; z-2; MPI_Bcast(&x, 1, MPI_INT, O, MPI_COMM_WORLD); MPI_Send(&y, 1, MPI_INT, 2, 43, MPI_COMM_WORLD); MPI_Bcast(&z, 1, MPI_INT, 1, MPI_COMM_WORLD) : Break; case 1: X = 3; y = 8; z = 5; MPI_Bcast(&x, 1, MPI_INT, O, MPI_COMM_WORLD); MPI_Bcast(&y, 1, MPI_INT, 1, MPI_COMM_WORLD); Break; case 2: X=6; y=7; z-8; MPI_Bcast(&z, 1, MPI_INT, O, MPI_COMM_WORLD); MPI_Recv(&x, 1, MPI_INT, , 43, MPI_COMM_WORLD, &status); MPI_Bcast(&y, 1, MPI_INT, 1, MPI_COMM_WORLD); Break; } What are the values of x, y, and z on each process after the code has been executed PO P1 P2 Z 7 Three processors have the follow
