MPI - Printing in an order

Question

I\'m trying to write a function in C where every processor prints it\'s own data. Here is what i have:

void print_mesh(int p,int myid,int** U0,int X,int Y){
         


        

Answer 1

For debugging and development purposes, you can run each process in a separate terminal, so they print in their own terminal:

mpirun -np n xterm -hold -e ./output

n: number of processors
-hold: keeps xterm on after the program is done.
output: name of MPI executable
