Changelog for petsc_3_21_2-gnu-mpich-hpc-devel-3.21.2-2.1.x86_64.rpm :

* Thu Jul 25 2024 Andreas Stieger - fix missing libyaml requirement of -devel package boo#1228280
* Tue Jun 18 2024 Egbert Eich - Update to version 3.21: - General:
* Add single precision support for using HYPRE and MFEM
* Require Fortran 2003 compiler with `GET_COMMAND_ARGUMENT()` support for building PETSc with Fortran bindings - Sys:
* Add `PetscBench` an object class for managing benchmarks in PETSc
* Deprecate `PetscVoidFunction`, `PetscVoidStarFunction`, and `PetscErrorCodeFunction` typedefs in favor of `PetscVoidFn` and `PetscErrorCodeFn`.
* Add `PetscOptionsBoundedReal()` and `PetscOptionsRangeReal()`.
* Rename Petsc stream types to `PETSC_STREAM_DEFAULT`, `PETSC_STREAM_NONBLOCKING`, `PETSC_STREAM_DEFAULT`_WITH_BARRIER` and `PETSC_STREAM_NONBLOCKING_WITH_BARRIER`. The root device context uses `PETSC_STREAM_DEFAULT` by default. - PetscViewer:
* Change `PetscViewerRestoreSubViewer()` to no longer need a call to `PetscViewerFlush()` after it.
* Introduce `PetscOptionsRestoreViewer()` that must be called after `PetscOptionsGetViewer()` and `PetscOptionsGetViewers()` to ensure thread safety.
* Add `PetscViewerASCIIWORLDSetFileUnit()`. - VecScatter / PetscSF:
* Add MPI-4.0 persistent neighborhood collectives support. Use `-sf_neighbor_persistent` along with `-sf_type` neighbor to enable it.
* Add `PetscSFCreateStridedSF()` to communicate strided blocks of data/ - Vec:
* Add `VecGhostGetGhostIS()` to get the ghost indices of a ghosted vector.
* Add `-vec_mdot_use_gemv` to let `VecMDot()`, `VecMTDot()` use BLAS2 `gemv()` instead of custom unrolled kernel. Default is on.
* Add `-vec_maxpy_use_gemv` to let `VecMAXPY()` use BLAS2 `gemv()` instead of custom unrolled kernel. Default is off.
* `VecReplaceArray()` on the first Vec obtained from `VecDuplicateVecs()` with either of the two above
*_use_gemv options won’t work anymore. If needed, turn them off or use VecDuplicateVec() instead `VecScale()` is now a logically collective operation.
* Add `VecISShift()` to shift a part of the vector.
* `VecISSet()` does no longer accept NULL as index set.
* `VecLoad()` automatically determines whether the file was written using 32-bit or 64-bit indices, and files can read with PETSc built either way. - PetscSection:
* Add `PetscSectionGetBlockStarts()` and `PetscSectionSetBlockStarts()`.
* Add argument to `PetscSectionCreateGlobalSection()` that can ignore the local section permutation.

* Add function `MatProductGetAlgorithm()` `MATTRANSPOSEVIRTUAL`, `MATHERMITIANTRANSPOSEVIRTUAL`, `MATNORMAL`, `MATNORMALHERMITIAN` and `MATCOMPOSITE` now derive from `MATSHELL`. This implies a new behavior for those Mat, as calling `MatAssemblyBegin()`/ `MatAssemblyEnd()` destroys scalings and shifts for `MATSHELL`, but it was not previously the case for other `MatType`.
* Add function `MatGetRowSumAbs()` to compute vector of L1 norms of rows ([`B`]`AIJ` only).
* Add partial support for `MatBackwardSolve()`/`MatForwardSolve()` with `MATSOLVERMKL_PARDISO` and `MATSOLVERMKL_CPARDISO`.

* Add support to dump and load a matrix of `MATIS` type.
* Add dense representations of symmetric Broyden matrices `MATLMVMDBFGS`, `MATLMVMDDFP`, and `MATLMVMDQN`.
* Add `MATSELLHIP` and the corresponding HIP kernels for matrix-vector multiplication. - MatCoarsen:
* Add `MatCoarsenSetMaximumIterations()` with corresponding option `-mat_coarsen_max_it <4>`. The number of iteration of the coarsening method. Used for the HEM coarsener.
* Add `MatCoarsenSetThreshold()` with corresponding option `-mat_coarsen_threshold <-1>`. Threshold for filtering graph for HEM. Like GAMG < 0 means no filtering.
* Change API for several PetscCD methods used internally in `PCGAMG` and `MatCoarsen` (eg, change `PetscCDSetChuckSize()` to `PetscCDSetChunckSize()`), remove Mat argument from `PetscCDGetASMBlocks()`. - PC:
* Add `PCGAMGSetLowMemoryFilter()` with corresponding option `-pc_gamg_low_memory_threshold_filter`. Use the system `MatFilter` graph/matrix filter, without a temporary copy of the graph, otherwise use method that can be faster.

* `PCMAT` use `MatSolve()` if implemented by the matrix type.
* Add `PCLMVMSetUpdateVec()` for the automatic update of the LMVM preconditioner inside a SNES solve.
* Add `PCGAMGSetInjectionIndex()` with corresponding option `-pc_gamg_injection_index i,j,k...`. Inject provided indices of fine grid operator as first coarse grid restriction (sort of p-multigrid for C1 elements).
* Add `PC_JACOBI_ROWL1` to `PCJacobiType` to use (scaled) l1 row norms for diagonal approximation with scaling of off-diagonal elements.
* Add `PCJacobiSetRowl1Scale()` and `-pc_jacobi_rowl1_scale` scale to access new scale member of PC_Jacobi class, for new row l1 Jacobi.
* Add `-mg_fine_...` prefix alias for fine grid options to override `-mg_levels_...` options, like `-mg_coarse_...`.
* The generated sub-matrices in `PCFIELDSPLIT`, `PCASM`, and `PCBJACOBI` now retain any null space or near null space attached to them even if the non-zero structure of the outer matrix changes.
* Add support for multiple subdomain per MPI process in `PCBDDC`.

* Add function typedefs `SNESInitialGuessFn`, `SNESFunctionFn`, `SNESObjectiveFn`, `SNESJacobianFn`, and `SNESNGSFn`.
* Deprecate `DMDASNESFunction`, `DMDASNESJacobian`, `DMDASNESObjective`, `DMDASNESFunctionVec`, `DMDASNESJacobianVec`, and `DMDASNESObjectiveVec` in favor of `DMDASNESFunctionFn`, `DMDASNESJacobianFn`, `DMDASNESObjectiveFn`, `DMDASNESFunctionVecFn`, `DMDASNESJacobianVecFn`, and `DMDASNESObjectiveVecFn`. - SNESLineSearch:

* versionToTuple: ignore leading strings in package versions. i.e 5.3.3consortium -> 5.3.3
* Add error checks for integer overflow for MatSeqXAIJSetPreallocation when the user provides nnz[]. Otherwise PetscMalloc() can produce error messages with requests to absurds amount of memory.

* Don\'t generate an error if the user does not free all objects while using SuperLU_DIST.

* Remove ierr = VecSetInf(ksp->vec_sol);CHKERRQ(ierr); from KSPSetUp_Chebyshev() since ksp->vec_sol may not yet exist and it is not needed since VecSetInf(ksp->vec_sol) is set in KSPSolve() just before the actual solve if ksp->reason = KSP_DIVERGED_PC_FAILED.
* Remove mention of DMDAGetLocalInfoF90() since it does not exist, Fortran version has same name as C version.
* MATSHELL: matrix sizes may not be known at creation time.
* Pass PetscDrawSetSave() and PetscDrawSetSaveFinalImage() to PetscViewerGetSubViewer_Draw(). Otherwise MatView() on parallel matrices, for example, will not generate an image file.
