• How to get a workable environment
• How to make a branch and pull request.
• How to write web-pages based on ipynb with jupyter-book
• How to check the result of the building of the webpage

• What is an MPI communicator. What is the difference between MPI.COMM_WORLD and MPI.COMM_SELF.
• Introduction to ipyparallel (#6)
• How scatter gather works for MPI.COMM_WORLD. (#5)
• How alltoall works and how alltoallv works
• Neighbourhood communicators, and how they differ from the "standard" ones
• Create_dist_graph.
• alltoallv for neigh comms, how this can be efficiently used
• parallel mesh in fenicsx

Everyone should add a short section about themselves, with link to their personal webpage.
Could just be added to this issue, and I'll add it to the webpage.

Explain these variables, as they have impact on CI if we use OpenMPI (fail with oversubscription).
