Hi jeremiah, <br><br>It compiled without errors when I edited line number 267 as,<br><br>Graph g(edge_array, edge_array + num_arcs, weights, num_nodes);<br><br><br>But when I run the command  &quot; mpirun -np 2  ./a.out&quot; <br>

<br>Following errors occured,<br><br><br>**** Testing aborted.<br>**** 1 error detected<br>--------------------------------------------------------------------------<br>mpirun has exited due to process rank 0 with PID 19096 on<br>

node rise-02 exiting without calling &quot;finalize&quot;. This may<br>have caused other processes in the application to be<br>terminated by signals sent by mpirun (as reported here).<br>--------------------------------------------------------------------------<br>

<br>What does that mean ?? <br><br>
