421480d92be24cdb9933c60510b8e175c0a8d034 - - Replace MatMissingDiagonal() and MatMarkDiagonals_SeqXXX() with MatGetDiagonalMarkers_SeqXXX()

Sun, 19 Oct 2025 04:43:08 +0000

- Replace MatMissingDiagonal() and MatMarkDiagonals_SeqXXX() with MatGetDiagonalMarkers_SeqXXX() - Mat_SeqXXX->diag is not automatically created during MatAssemblyEnd() saving memory and time - Accessing Mat_SeqXXX->diag now requires the use of MatGetDiagonalMarkers_SeqXXX() except when the current values are known to be correct; for example during numerical factorizations and solves - Mat_SeqXXX->diag is now never shared among matrices; hence the free_diag flag is gone. That was always a risky proposition since any of the owning matrices could chang the values thus making them incorrect for other owners. List of files: /petsc/src/mat/impls/sell/seq/sell.h

07425a8d4172ec73b7b53c5ce4d6ba1b92fe45cf - This MR optimize some MAT[SB]AIJ operations related to the diagonal

Sat, 18 Oct 2025 18:21:36 +0000

This MR optimize some MAT[SB]AIJ operations related to the diagonalThe longer term goal is to refactor some Mat_SeqXXX non-numeric code to make it easier to also implement it on GPUs. For example, MatGetDiagonal() and friendsThis commit- MatMarkDiagonal_SeqAIJ/ELL() - now use change in mat->nonzerostate to determine if it needs to recheck the diagonal locations - sets diagDense flag for a complete diagonal- MatInvertDiagonal_SeqAIJ/ELL() - now uses change in mat->state to determine if diagonal entries and inverses need to be recomputed - name changed to MatInvertDiagonalForSOR_SeqAIJ/ELL() for code clarity- Added MatInvertDiagonal_SeqAIJ_Inode() for use by MatSOR_SeqAIJ_Inode() - now uses change in mat->state to determine if block diagonal entries and inverses need to be recomputed List of files: /petsc/src/mat/impls/sell/seq/sell.h
