Enum Matching 

pub enum Matching {
    None,
    Auto,
    MaxDiagCount,
    MaxMinDiag,
    MaxMinDiagAlt,
    MaxDiagSum,
    MaxDiagProduct,
}

Specifies the matching algorithm (cuDSS only)

Important: Note that the default is Matching::None.

Note: It is recommended to select Matching::Auto when dealing with unsymmetric matrices containing some zero entries on their diagonal.

See: https://docs.nvidia.com/cuda/cudss/types.html#cudssmatchingalg-t

Variants

None

No matching algorithm (default)

CUDSS_MATCHING_ALG_NONE

Auto

Automatic selection

Same as CUDSS_MATCHING_ALG_MAX_DIAG_PRODUCT (the most robust option). Matching with scaling; requires matrix values during analysis.

CUDSS_MATCHING_ALG_AUTO

MaxDiagCount

Column permutation to maximize the number of diagonal entries (values arbitrary). MC64 JOB=1. Does not use matrix values; not recommended unless justified.

CUDSS_MATCHING_ALG_MAX_DIAG_COUNT

MaxMinDiag

Column permutation to maximize the smallest value on the diagonal. MC64 JOB=2.

CUDSS_MATCHING_ALG_MAX_MIN_DIAG

MaxMinDiagAlt

Alternate algorithm to maximize the smallest value on the diagonal. MC64 JOB=3. May differ in performance from CUDSS_MATCHING_ALG_MAX_MIN_DIAG.

CUDSS_MATCHING_ALG_MAX_MIN_DIAG_ALT

MaxDiagSum

Column permutation to maximize the sum of diagonal entries. MC64 JOB=4.

CUDSS_MATCHING_ALG_MAX_DIAG_SUM

MaxDiagProduct

Column permutation to maximize the product of diagonal entries; also computes row/column scaling so that nonzero diagonal entries are 1 in absolute value and off-diagonal entries are ≤ 1. MC64 JOB=5. Most impactful for accuracy; requires matrix values during analysis.

CUDSS_MATCHING_ALG_MAX_DIAG_PRODUCT
