      abstract     = {Rayleigh-Benard convection is a benchmark problem for
                      incompressible turbulent flows. Turbulence is typically
                      discretized with high resolution in space in order to
                      capture all relevant length scales, but the time direction
                      is usually not treated with the same rigor. We show that
                      high-order spectral deferred correction (SDC) and
                      Runge-Kutta (RK) methods have improved stability over first
                      order RK, mitigating the additional computational cost per
                      time step. Furthermore, we demonstrate improved accuracy
                      with increasing order of time integration in key averaged
                      quantities. We find that diagonal preconditioners in SDC
                      allow to either get faster time to solution as a RK method
                      of the same order or to get higher order and accuracy with
                      similar time to solution as the RK method only at the
                      expense of additional hardware.},
