Function Documentation

core_clr2fr()

static pastix_fixdbl_t core_clr2fr ( core_clrmm_t *  params, const pastix_lrblock_t *  AB, pastix_trans_t  transV  )

inlinestatic

Perform the addition of the low-rank matrix AB and the full-rank matrix C.

Parameters

[in,out]

params

The LRMM structure that stores all the parameters used in the LRMM functions family. On exit, the C matrix is udpated with the addition of AB.

See also

core_clrmm_t

Parameters

[in]	AB	The low-rank structure of the AB matrix to apply to C.
[in]	transV	Specify if AB->v is stored normally or transposed. If PastixNoTrans, AB->v is stored normally for low-rank format. If PastixTrans, AB->v is stored transposed. If PastixConjTrans, AB->v is stored transposed, and conjf() must be applied to the matrix.

Returns

The number of flops required to perform the operation.

core_clr2lr()

static pastix_fixdbl_t core_clr2lr ( core_clrmm_t *  params, const pastix_lrblock_t *  AB, pastix_trans_t  transV  )

inlinestatic

Perform the addition of the low-rank matrix AB and the low-rank matrix C.

Parameters

[in,out]

params

The LRMM structure that stores all the parameters used in the LRMM functions family. On exit, the C matrix is udpated with the addition of AB.

Parameters

[in]	AB	The low-rank structure of the AB matrix to apply to C.
[in]	transV	Specify if AB->v is stored normally or transposed. If PastixNoTrans, AB->v is stored normally for low-rank format. If PastixTrans, AB->v is stored transposed. If PastixConjTrans, AB->v is stored transposed, and conjf() must be applied to the matrix.

Returns

The number of flops required to perform the operation.

core_clr2null()

static pastix_fixdbl_t core_clr2null ( core_clrmm_t *  params, const pastix_lrblock_t *  AB, pastix_trans_t  transV, int  infomask  )

inlinestatic

Perform the addition of the low-rank matrix AB into the null matrix C.

Parameters

[in,out]

params

The LRMM structure that stores all the parameters used in the LRMM functions family. On exit, the C matrix contains the product AB aligned with its own dimensions.

core_clrmm_t

Parameters

[in]	AB	The low-rank structure of the AB matrix to apply to C.
[in]	transV	Specify if AB->v is stored normally or transposed. If PastixNoTrans, AB->v is stored normally for low-rank format. If PastixTrans, AB->v is stored transposed. If PastixConjTrans, AB->v is stored transposed, and conjf() must be applied to the matrix.
[in]	infomask	Mask of informations returned by the core_cxx2lr() functions. If CORE_LRMM_ORTHOU is set, then AB.u is orthogonal, otherwise an orthogonalization step is added before adding it to C.

Returns

The number of flops required to perform the operation.
