Hands-on: Collective operations
mpi/collectives/First, write a program where rank 0 sends an array containing numbers from 0
to 7 to all the other ranks using collective communication.Next, we continue with four MPI tasks with following initial data vectors:
in the buffer are initialized to -1. Implement a program that sends and
receives values from the data vectors to receive buffers using a single
collective communication routine for each case, so that the receive buffers
will have the following values. You can start from the skeleton file
