Hello, I read in the email archive (from 2016) that, at that time, the number of synchronized dof (in MPI/ghost cells sense) is 3 or 4. Is that still the case ? I would like to use PETSc for solving the Boltzmann equation (via Discreet velocity method, which means a lot of dof per node). Is it the same for DMPlex ? Thanks, best regards, Yann
