Abstract
Article Highlights The use of a p-multigrid method significantly reduces the CPU timings for higher values of the spline degree. The Multigrid Reduction in Time method shows both strong and weak scalability up to 2048 cores. Iteration numbers are independent of the number of time steps, mesh width and spline degree.
