Write MPI code to sum a vector of values vect1[i]. The result should be placed in a variable called totsum. Initialize your vector to integers such that vect1[i] = i+1. Your vector should be split among the available processes, and each process should add its own components. Use an MPI reduction operator to sum the results on the master process. Your code should work on any number of processes. Compute the runtime of your code. Run with differfent number of threads and different length of vectors
