=============
Changes: 3.10
=============
.. rubric:: General:
- Removed --with-errorchecking configure option.
- Added new command line option -viewfromoptions to disable
``XXXViewFromOptions()`` calls.
.. rubric:: Configure/Build:
- Removed --with-viewfromoptions configure option in favor of the
new command line option -viewfromoptions.
- Following options are renamed to have more consistent names:
::
--with-packages-dir -> --with-packages-download-dir
--with-external-packages-dir -> --with-packages-build-dir
--package-dirs -> --with-packages-search-path
--search-dirs -> --with-executables-search-path
.. rubric:: IS:
.. rubric:: PetscDraw:
.. rubric:: PF:
.. rubric:: Vec:
.. rubric:: VecScatter:
.. rubric:: PetscSection:
.. rubric:: Mat:
- MatNullSpaceTest() now respects the options prefix of the provided
Mat.
- Added MatMatTransposeSolve() to MUMPS interface.
- Added -mat_mumps_use_omp_threads [m] option to better support
OpenMP in MUMPS.
- Added MatPartitioningViewFromOptions().
- Added MatPartitioningApplyND() to compute a nested dissection
ordering of a matrix.
- Deprecated MatISGetMPIXAIJ() in favour of MatConvert().
- Added new matrix types for limited-memory variable-metric
(MATLMVM) approximations of Jacobians.
- Added MATAIJSELL, a sub-type of AIJ that uses SELL format
internally for SELL-optimized operations.
.. rubric:: PC:
- PCKSPGetKSP() now raises an error if called on a PC which is not
of type PCKSP
- Added PCKSPSetKSP()
- Added new PC based on the new LMVM matrices.
.. rubric:: KSP:
- The KSP viewing options have changed. Now
- -ksp_compute_eigenvalues becomes -ksp_view_eigenvalues ascii
- -ksp_plot_eigenvalues becomes -ksp_view_eigenvalues draw
- -ksp_plot_eigencontours becomes -ksp_view_eigenvalues
draw::draw_contour
- -ksp_compute_eigenvalues_explicitly becomes
-ksp_view_eigenvalues_explicit ascii
- -ksp_plot_eigenvalues_explicitly becomes
-ksp_view_eigenvalues_explicit draw
- -ksp_compute_singularvalues becomes -ksp_view_singularvalues
ascii
- -ksp_final_residual becomes -ksp_view_final_residual
- ``KSPLSQR``
- Computes now an estimate of the operator's norm in the same way
as Saunders and MATLAB, and uses it in the type-specific
stopping criterion ``KSPLSQRConvergedDefault()``; this now
gives the same number of iterations as MATLAB's ``lsqr()``.
- Added ``-ksp_lsqr_exact_mat_norm`` and
``KSPLSQRSetExactMatNorm()`` to optionally compute and use the
exact Frobenius norm instead of the estimate.
- ``KSPLSQRMonitorDefault()`` and ``-ksp_lsqr_monitor`` now
additionally print the (estimate of) the operator's norm.
- Allow setting ``-ksp_convergence_test lsqr`` (it's a default
for ``KSPLSQR``, though).
- ``KSPLSQRSetStandardErrorVec()`` is replaced by
``KSPLSQRSetComputeStandardErrorVec()`` which now specifies
whether standard error vector should be computed instead of
setting the vector;
- likewise, option ``-ksp_lsqr_set_standard_error`` is replaced
by ``-ksp_lsqr_compute_standard_error``.
- Renamed ``KSPLSQRGetArnorm()`` to ``KSPLSQRGetNorms()`` and
removed its ``rhs_norm`` argument.
- Renamed ``KSPLSQRDefaultConverged()`` to
``KSPLSQRConvergedDefault()`` merged with
``KSPConvergedLSQR()``.
.. rubric:: SNES:
- SNESSetTolerances() and -snes_max_funcs now accept -1 to indicate
unlimited number of function evaluations.
.. rubric:: SNESLineSearch:
.. rubric:: TAO:
- Added bound-constrained Newton-Krylov methods (BNLS, BNTR, BNTL).
- All quasi-Newton methods updated to use the new LMVM Mat objects.
- Added a bound-constrained quasi-Newton line search (BQNLS) method
that re-uses BNLS infrastructure to replace BLMVM on next release.
- Bound-constrained conjugate gradient method expanded with new CG
update types and nonlinear preconditioning.
- Removed ``-tao_type test``.
- Gradient testing can now be accessed with the options
``-tao_test_gradient``, ``-tao_test_gradient_view``, and Hessian
testing can be done with ``-tao_test_hessian``,
``-tao_test_hessian_view`` (also works for matrix-free Hessian).
.. rubric:: TS:
- Added symplectic time integrators for separable Hamiltonian
systems (-ts_type basicsymplectic).
.. rubric:: DM/DA:
- Renamed ``DMDAGetReducedDMDA()`` to
``DMDACreateCompatibleDMDA()``.
- Added DMGetCompatibility() and implementation for DMDA
.. rubric:: DMPlex:
- Added an interface DM and boundary label to
DMPlexCreateHybridMesh()
- More refined control of ``DMView()`` when
``PetscViewerType=PETSCVIEWERHDF5``. ``PetscViewerFormat`` can now
be one of
``{PETSC_VIEWER_HDF5_VIZ, PETSC_VIEWER_HDF5_XDMF, PETSC_VIEWER_HDF5_PETSC, PETSC_VIEWER_DEFAULT}``.
- Parallel mesh load (i.e. mesh distributed right from beginning)
with ``DMLoad()``, ``PetscViewerType=PETSCVIEWERHDF5`` and
``PetscViewerFormat=PETSC_VIEWER_HDF5_XDMF``, or
``DMPlexCreateFromFile()`` and ``-dm_plex_create_from_hdf5_xdmf``.
.. rubric:: PetscViewer:
Added argument to ``PetscViewerVTKAddField()`` to allow skipping of
DM check as fields are added
.. rubric:: SYS:
.. rubric:: AO:
.. rubric:: Sieve:
.. rubric:: Fortran:
