After executing MPI_Send() for the first time in the root process, my
program blocks.

int the root process, I have:
cout << "executing send for the " << i-1 << "th time" <<  endl;
   MPI_Send(&A[i-1], n*m/iWorldSize, MPI_INT, j, itag, MPI_COMM_WORLD);
   cout << "executed send for the " << i << "th time" <<  endl;
   }//end while

and in the slave processes I have

 MPI_Status status;

  int *buffer = new int[m*(n/iWorldSize)];
      cout << "\n\n\n**********Executing receive*******" << endl;
      MPI_Recv(&buffer, m*(n/iWorld

where did I go wrong?

Thank you
