Improve the propagation of function domain error handling in SNES, especially in the line search routines.Due to the object layering of SNESLineSearch under SNES there is some code duplication include both SNESLineSearchReason and SNESConvergedReason and SNESCheckFunctionNorm() and SNESLineSearchCheckFunctionNorm() and Jacobian friendsReported-by: david.knezevic@akselos.com List of files: /petsc/src/snes/impls/fas/fas.c

Wed, 27 Aug 2025 02:18:34 +0000

SNESLinesearch: Minor improvements- add missing configuration options in the documentation of the line searches (some of the available options were not listed), and consistently list their respective default values- add proper convergence criteria for the secant method in the L2 line search based on ltol and atol (otherwise, the secant method is mostly running for the maximum number of iterations)- fix a small bug in the CP line search, where steptol * lambda was used to check for convergence based on the change of lambda instead of the ltol parameter- rename sneslinesearch->maxstep to sneslinesearch->maxlambda in the options database to be consistent with its purpose in the algorithms- rename SNESLineSearchL2 to SNESLineSearchSecant to better represent its underlying approach List of files: /petsc/src/snes/impls/fas/fas.c

Fortran 90: fully embrace After 34 years!- deprecate use of 'F90' in Fortran function names- use Fortran pointers when appropriate- the new Fortran API is not backward compatible with previous versions!- also clean up inconsistent PETSc code detected by new Fortran generation tools- drop use of bfort- automatically generate all the Fortran PETSc objects, enums etc from the include files- generate most of the Fortran interface definitions and functions from the source code- simplify the number and organization of Fortran modulesCo-authored-by: Jose E.

cd791dc2c132c70a186d4b461f371a0a6f494201 - Fix PetscOptionsGetViewer() so it works in a thread-safe way

Tue, 21 Nov 2023 22:06:25 +0000

Fix PetscOptionsGetViewer() so it works in a thread-safe wayWhen PetscOptionsGetViewer() returns, for example, PETSC_VIEWER_STDOUT_SELF the same object is sharedby all threads that call PetscOptionsGetViewer(). In the previous code PetscObjectReference() anddereference (via PetscViewerDestroy() where called on the viewer by multiple threads after the viewerwas accessed thus corrupting the object.This branch introduces a PetscOptionsRestoreViewer() that allows not doing the referencing and dereferencingon persistant viewers, thus removing the specific race condition above.Other possible solutions includeUse a lock on each PetscObjectReference/Dereference() just in case they are shared. Could be time consuming so onecould mark each object as either threadshared or independent and only do the locks on threadshared objects. This lowersthe cost but would require more extensive changes to PETSc infrastructure. And I do not know if this shared/not shared modelis what we need in the long run, though it might be.
