- Check for last step & adjust dt if necessary
- Dump log information, n, t(n), dt(n), MAX_MACH(n-1), etc..
- Check output/analysis: t(n) < tout < t(n)+dt(n)
- write to disk/call analysis using {U(n), t(n), dt(n)}
- Advance solution using dt(n): U(n) --> U(n+1)
- Increment t(n+1) = t(n) + dt(n)
- [MPI] Show dominant time step (n)
- [MPI] Get next time step dt(n+1)
- [MPI] reduction operations (n)
- Increment n --> n+1
