Enumeration Type Documentation

ColPerm

enum mfem::superlu::ColPerm

Define the type of column permutation.

Enumerator
NATURAL	Natural ordering.
MMD_ATA	Minimum degree ordering on structure of \( A^T*A \).
MMD_AT_PLUS_A	Minimum degree ordering on structure of \( A^T+A \).
COLAMD	Approximate minimum degree column ordering.
METIS_AT_PLUS_A	Sequential ordering on structure of \( A^T+A \) using the METIS package.
PARMETIS	Sequential ordering on structure of \( A^T+A \) using the PARMETIS package.
ZOLTAN	Use the Zoltan library from Sandia to define the column ordering.
MY_PERMC	User defined column permutation.

Fact

enum mfem::superlu::Fact

Define the information that is provided about the matrix factorization ahead of time.

Enumerator
DOFACT	No information is provided, do the full factorization.
SamePattern	Matrix A will be factored assuming the sparsity is the same as a previous factorization. Column permutations will be reused.
SamePattern_SameRowPerm	Matrix A will be factored assuming the sparsity is the same and the matrix as a previous are similar as a previous factorization. Column permutations and row permutations will be reused.
FACTORED	The matrix A was provided in fully factored form and no factorization is needed.

Definition at line 93 of file superlu.hpp.

IterRefine

enum mfem::superlu::IterRefine

Define how to do iterative refinement.

Enumerator
NOREFINE	No interative refinement.
SLU_SINGLE	Iterative refinement accumulating residuals in a float.
SLU_DOUBLE	Iterative refinement accumulating residuals in a double.
SLU_EXTRA	Iterative refinement accumulating residuals in a higher precision variable.

RowPerm [1/2]

enum mfem::superlu::RowPerm

Enumerator
NOROWPERM	No row permutation.
LargeDiag
MY_PERMR	User defined row permutation.
NOROWPERM	No row permutation.
LargeDiag_MC64	Duff/Koster algorithm to make the diagonals large compared to the off-diagonals. Use LargeDiag for SuperLU version 5 and below.
LargeDiag_HWPM	Parallel approximate weight perfect matching to make the diagonals large compared to the off-diagonals. Option doesn't exist in SuperLU version 5 and below.
MY_PERMR	User defined row permutation.

Definition at line 32 of file superlu.hpp.

LargeDiag_HWPM	Parallel approximate weight perfect matching to make the diagonals large compared to the off-diagonals. Option doesn't exist in SuperLU version 5 and below.
MY_PERMR	User defined row permutation.
