  1. New: Added PETScWrappers::PreconditionParaSails and +PETScWrappers::PreconditionNone. PETScWrappers::PreconditionParaSails +implements the interface to use the ParaSails sparse approximate +inverse preconditioner from the HYPRE suite. ParaSails supports +parallel distributed computations and can handle nonsymmetric +and also indefinite problems. PETScWrappers::PreconditionNone +implements non-preconditioning in PETSc which can be of use +together with the PETScWrappers::MatrixFree class. + +

  2. New: Added SparsityTools::distribute_sparsity_pattern() for BlockCompressedSimpleSparsityPattern. This allows parallel computations with distributed::Triangulation and PETScWrappers::MPI::BlockSparseMatrix. -- 2.39.5
