Exercise .. Write an MPI program to sum the squares of the ranks of the processes. The root process (process with rank 0) receives the squares of each process and makes the sum. Each process from (1 to n) calculates the square of its rank and sends it to the root process. The root process calculates its rank square and prints it and prints the sum of the squares of the ranks of all processes. When the root process receives a number from another process i its prints: . The root process received the number i*i from process i Here is an example of the output of the program when run with 4 processes: The root process received the number 1 from process 1 The root process received the number 4 from process 2 The root process received the number 9 from process 3 The square of process is equal to 0 The sum of the squares of the ranks of all processes is: 14 MK 27 27
