What's the issue?

I'm guessing it's because with std::cout every processor prints the same statement when run in parallel. We should use pcout instead. Is this correct, @landinjm?

With std::cout each processor will write whenever it reaches that section of code. It is better to have a dedicated output on the rank 0 process (as we do with pcout).
