==============
Changes: 2.1.0
==============
Changes
-------
(See `Features`_ below)
.. rubric:: General:
- Simpler interface for structured grids, see
src/snes/examples/tutorials/ex5.c
- "System routines" including PLog..., Options..., Viewer...,
Draw...., FList...,OList... now all begin with the string Petsc.
For example, PetscOptionsGetInt() and PetscLogBegin().
- The calling sequence for PetscMalloc() was changed to return and
error code and deliver the pointer as a new final argument. Due to
this change, the macros CHKPTRA() and CHKPTRQ() were dropped.
.. rubric:: AO (Application Orderings):
.. rubric:: TS (Timestepping Solvers):
.. rubric:: SNES (Nonlinear Solvers):
.. rubric:: SLES (Linear Solvers):
.. rubric:: KSP (Krylov Subspace Methods):
.. rubric:: PC (Preconditioners):
.. rubric:: MAT (Matrices):
- When using MatCreate(), you must follow with a MatSetType() or
MatSetFromOptions() before using the matrix.
- Changed
``int MatShellSetOperation(Mat,MatOperation,void*);``
to
``int MatShellSetOperation(Mat,MatOperation,void(*)());``
- Changed
``int MatShellGetOperation(Mat,MatOperation,void**);``
to
``int MatShellGetOperation(Mat,MatOperation,void(**)());``
- Changed IncompleteCholesky to ICC
.. rubric:: DA (Distributed Arrays):
- Changed the DAMG routines to DMMG routines.
- DAGetColoring() now has new second argument that takes either
IS_COLORING_GLOBAL or IS_COLOR_GLOBAL and a new third argument
that takes the matrix type of either MATMPIAIJ or MATMPIBAIJ.
.. rubric:: VEC (Vectors):
- Changed ``int VecSetOperation(Vec,VecOperation,void*);`` to
``int VecSetOperation(Vec,VecOperation,void(*)());``
.. rubric:: IS (Index Sets):
.. rubric:: General:
.. rubric:: Draw (Graphics):
.. rubric:: Viewers:
.. rubric:: System:
.. rubric:: Error Handling:
- CHKERRA() is now obselete; use CHKERRQ() instead. Changed the
calling sequence of SETERRQ() to eliminate the second input
parameter.
.. rubric:: Event Logging:
.. rubric:: Fortran Interface:
Features
--------
(See `Changes`_ above)
.. rubric:: General:
- Simpler interface for structured grids, see
src/snes/examples/tutorials/ex5.c
- Complete infrastructure for parallel multigrid for linear and
nonlinear problems on structured grids. See
src/snes/examples/tutorials/ex19.c
- Added manual pages for PETSc objects, enums etc.
- Added html version of all source code and examples, accessible
from docs/index.html and the manual pages.
.. rubric:: AO (Application Orderings):
.. rubric:: TS (Timestepping Solvers):
.. rubric:: SNES (Nonlinear Solvers):
.. rubric:: SLES (Linear Solvers):
.. rubric:: KSP (Krylov Subspace Methods):
- Added support for "diagonal scaling" of preconditioned system as
required by most ODE integrators via PCDiagonalScaleSet().
.. rubric:: PC (Preconditioners):
.. rubric:: MAT (Matrices):
- Added the Henry Tufo/Paul Fischer libtfs scalable parallel direct
solver for MPIAIJ matrices.
- Added routine MatFDColoringSetRecompute().
.. rubric:: DA (Distributed Arrays):
- Added DAVecGetArray() to access the multidimensional arrays
directly in the global parallel indexing. See
src/snes/examples/tutorials/ex5.c and ex19.c
- Add DAGetLocalVector()/DARestoreLocalVector() for inexpensive
access to local work vectors.
.. rubric:: VEC (Vectors):
- Added DMComposite routines to help with PDE optimization and
multicomponent PDEs.
.. rubric:: IS (Index Sets):
.. rubric:: PF:
.. rubric:: Draw (Graphics):
.. rubric:: Viewers:
