2a8381b23c702518c6b1ccbeafee50b9375df0e4 - Add automatic generated fortran support for setting and returning contexts

Tue, 13 Jan 2026 04:45:38 +0000

Add automatic generated fortran support for setting and returning contextsMajor cleanup of the code for setting and returning application (previously called user) contexts - PetscCtx ctx is now the standard for passing in contexts - PetscCtxRt ctx is the standard for passing out contexts, including context destroy routines based on PetscCtxDestroyFnBoth of these are typedef to void*Also removed most use of user and userctx for context arguments now consistently named ctxImproved documentation on PetscCtx and PetscCtxRt and on how to use contexts (including getting them) from Fortran List of files: /petsc/src/ksp/pc/impls/mpi/pcmpi.c

Thu, 17 Jul 2025 01:39:09 +0000

Fix a race condition in PCMPISolve() when using Unix shared memory.The 0th rank accesses the solution of the other rocesses before the other processes have finished updating the final solution locally. This cannot happen with the MPI communication based version because the communication is done with an MPI_Allgatherv() that blocks on the processes getting to that point before copying over the data.Reported-by: Marsha Berger List of files: /petsc/src/ksp/pc/impls/mpi/pcmpi.c

Thu, 20 Feb 2025 06:12:11 +0000

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.
