Utilities::MPI::all_gather(comm,
locally_owned_dofs())
upon the first invocation, including global communication. Use Utilities::MPI::all_gather(comm, dof_handler.locally_owned_dofs())
instead if using up to a few thousands of MPI ranks or some variant involving local communication with more processors. Utilities::MPI::all_gather(comm,
locally_owned_dofs_mg())
upon the first invocation, including global communication. Use Utilities::MPI::all_gather(comm, dof_handler.locally_owned_dofs_mg())
instead if using up to a few thousands of MPI ranks or some variant involving local communication with more processors. Utilities::MPI::all_gather(comm, n_locally_owned_dofs()
upon the first invocation, including global communication. Use Utilities::MPI::all_gather(comm, dof_handler.n_locally_owned_dofs()
instead if using up to a few thousands of MPI ranks or some variant involving local communication with more processors. const
second argument. const
second argument. selected_dofs
has to have a length equal to all global degrees of freedom. Consequently, this does not scale to very large problems, and this is also why the function is deprecated. If you need the functionality of this function for parallel triangulations, then you need to use the other DoFTools::extract_boundary_dofs() function that returns its information via an IndexSet object.
