Step-5: PFASST

In this step, we will show how pySDC can do PFASST runs (virtually parallel for now).

• Part A: Multistep multilevel hierarchy. How a controller holds several time steps, each with its levels.

• Part B: My first PFASST run. The heat equation with 1 to 16 parallel time steps.

• Part C: Advection and PFASST. The same for an advection problem, where the iteration counts grow.

Each part is a Python script in jupytext “percent” format: run it with python, open it as a notebook in Jupyter, or read it on the website, where it is executed with every build.
