Changes: Development

General:

Configure/Build:

• Make SYCL a devicePackage, i.e., builds --with-sycl now have PETSC_HAVE_DEVICE defined

• Add the option --with-devicelanguage to compile PetscDevice code using either a C or C++ compiler

Sys:

• Add PetscCallHYPRE() to check HYPRE error codes and print error messages on failure

Event Logging:

• Add two approaches for GPU energy monitoring: -log_view_gpu_energy and -log_view_gpu_energy_meter

• Add API PetscLogGpuEnergy(), PetscLogGpuEnergyMeter(), PetscLogGpuEnergyMeterBegin() and PetscLogGpuEnergyMeterEnd() for GPU energy monitoring

PetscViewer:

• Change the final argument of PetscViewerGLVisSetFields() to PetscCtxDestroyFn *. This means the destroy function must dereference the argument before operating on it

PetscDraw:

AO:

IS:

VecScatter / PetscSF:

PF:

Vec:

PetscSection:

PetscPartitioner:

Mat:

• Change the destroy() function argument of MatShellSetMatProductOperation() to type PetscCtxDestroyFn *. This means the destroy function must dereference the argument before operating on it

• Remove MatMissingDiagonal(). Developers should use MatGetDiagonalMarkers_SeqXXX() when the functionality is needed

• Change MatSetOption(A, MAT_HERMITIAN, PETSC_TRUE) for MatSBAIJ to no longer automatically set the option MAT_SYMMETRIC to PETSC_FALSE. It is now the duty of the user to call MatSetOption(A, MAT_SYMMETRIC, PETSC_FALSE) if a MatSBAIJ is Hermitian but not symmetric

MatCoarsen:

PC:

• Add multi-precision support for MUMPS. One could use -pc_precision <single, double> to set the precision to be used by MUMPS, which can be different from PetscScalar’s precision

KSP:

• Remove KSPHPDDMPrecision in favor of PetscPrecision

SNES:

• Change the destroy() function argument of SNESSetConvergenceTest() to type PetscCtxDestroyFn *. This means the destroy function must dereference the argument before operating on it

SNESLineSearch:

TS:

• Change the destroy() function argument of TSTrajectorySetTransform() to type PetscCtxDestroyFn *. This means the destroy function must dereference the argument before operating on it

• Add TSPseudoComputeFunction() to get nonlinear residual while avoiding recalculation if possible

• Remove unused TSPseudoVerifyTimeStepDefault()

• Remove TSPseudoComputeTimeStep() and TSPseudoVerifyTimeStep()

TAO:

PetscRegressor:

DM/DA:

• Change the final argument of DMShellSetDestroyContext() to PetscCtxDestroyFn *. This means the destroy function must dereference the argument before operating on it

DMSwarm:

DMPlex:

• Add DMPlexVecGetClosureAtDepth()

FE/FV:

DMNetwork:

DMStag:
