Detailed Description

Typedef Documentation

pastix_ktype0_t

typedef enum pastix_ktype0_e pastix_ktype0_t

List of the Level 0 events that may be traced in PaStiX.

This is only the high level steps.

pastix_ktype_t

typedef enum pastix_ktype_e pastix_ktype_t

List of the Level 1 events that may be traced in PaStiX.

This is the main information that traces all the major kernels during the factorization step.

pastix_ktype2_t

typedef enum pastix_ktype2_e pastix_ktype2_t

List of the Level 2 events that may be traced in PaStiX.

This is the low-level information that traces all the individual calls to blas/lapack routines in the code. It is used to compute the number of flops in low-rank compression, and to distinguish the amount of flops spent in each part of the low-rank updates.
