KSPSetOperators() no longer has the MatStructure argument. The Mat objects now track that information themselves. Use KPS/PCSetReusePreconditioner() to prevent the recomputation of the preconditioner if the operator changed in the way that SAME_PRECONDITIONER did with KSPSetOperators()

SNES/TS still need to be cleaned up to better utilize the new interfaces

completed cleanup of removal of matrix pointers to compute jacobian routines

update changes file

fixed tao examples to no longer use Mat* arguments for Jacobian/Hessian etc computations

tao: namespace TAO subvec and submat routines and make intern

fix Tao unconventional naming of TAOLINESEARCH_XXX_CTX TAOLINESEARCH_MT etc

changed TaoTerminationReason TaoConvergedReason
changed TaoLineSearchTerminationReason to TaoLineSearchConvergedReason

reason: consistency with the rest of PETSc

updates to Tao per request of Lisandro for Petsc4py

* I would like to have TaoGetConstraintTolerances(), right now I'm
defining it in petsc4py as shown in the link below:

* Look at all these definitions, they should be exposed in the C API
to be able to call e.g. TaoSetType(tao,TAOLMVM);

Also removed -tao_method, removed tao_ from names of tao methods and fixed some tao source code formatting

show more ...

fixed more Tao print format statements

set tao tolerances for single precision

BTW: there are all kinds of crazy tolerances all over the place; needs to be rationalized

changed TaoSolver usage to Tao

added petsc to front of tao public includes

move tao vector operations over to Vec directory, fix a couple names and calling sequences

fixed quote marks for includes to <>

remove tao-private include directory, private goes into petsc-private

tao: remove trailing spaces from sources

tao: untabify sources

more format cleanup of tao

update more tao code to modern PETSc, remove PETSC_NULL, some formating

removed some uses of %G updated those files to use proper PETSc style code

tao: remove unused MANSECs from makefiles

tao: libtao -> libpetsctao [as gmake/cmake builds automatically add petsc prefix]

TAO: Update for no type arguments in PetscNew and PetscNewLog
