Consider the following code segment of an MPI program and answer the following question. int rank, tag=1; MPI Status Stat; MPI Init(&argc, &argv); MPI Comm rank (MPI_COMM_WORLD, &rank); int x = rank + 1; if (rank } } == 0) { proc = 1; MPI Recv(&x, 1, MPI_INT, proc, tag, MPI_COMM_WORLD, &Stat); x = x + 5; MPI Send (&x, 1, MPI_INT, proc, tag, MPI_COMM_WORLD); x = x + 2* rank; else if (rank proc = 0; MPI Send (&x, 1, MPI_INT, proc, tag, MPI_COMM_WORLD); x = x + 3; == Answer: 1) { MPIR Recv(&x, 1, MPI_INT, proc, tag, MPI_COMM_WORLD, & Stat); x = x + 2* rank; printf("Task %d: Received %d"\n", rank, x); If the above program is run using 3 processors, what is the output? Write down the output that will be shown in the standard output (output generated by the printf statement). I

Problem Statement: The mathematician Conway imagined a game, called game of life, whichconsidered cells that are susceptible to reproduce, disappear, or survive when they obey certainrules. These cells are represented by elements on a grid of squares, where a grid has an arbitrarysize. Thus, each cell (except those on the boundaries of the grid) is surrounded by eight squaresthat contain other cells. The rules are stated as follows:1. Survival: Each cell that has two or three adjacent cells survives until the next generation.2. Death: Each cell that has at least four adjacent cells disappears (or dies) by overpopulation.Also, each cell that has at most one adjacent cell dies by isolation.3. Birth: Each empty square (i.e., dead cell) that is adjacent to exactly three cells gives birthto a new cell for the next generation.It is worth noting that all births and deaths occur at the same time during a generation.Write a program that simulates this game and displays all successive…
