#include <sunperf.h> void StatFree(SuperLUStat_t *stat); void StatFree_64(SuperLUStat_t_64 *stat);
Oracle Solaris Studio Performance Library StatInit(3P) NAME StatFree - frees storage that was previously allocated to hold perfor- mance statistics of the SuperLU solver. SYNOPSIS #include <sunperf.h> void StatFree(SuperLUStat_t *stat); void StatFree_64(SuperLUStat_t_64 *stat); PURPOSE Most of the computational routines use a structure to record certain kinds of performance data, namely the time and number of floating point operations in each phase of the computation, and data about the size of the matrices L and U. These statistics are collected during the compu- tation and stored in a variable of type SuperLUStat_t: typedef struct { int *panel_histo; double *utime; float *ops; int TinyPivots; int RefineSteps; } SuperLUStat_t; typedef struct { long *panel_histo; double *utime; float *ops; long TinyPivots; long RefineSteps; } SuperLUStat_t_64; where panel_histo is histogram of panel size distribution utime is running time at various phases ops is operation count at various phases TinyPivots is number of tiny pivots RefineSteps is number of iterative refinement steps StatFree frees the storage of the fields panel_histo, utime and ops. ARGUMENTS SuperLUStat_t *stat (input/output) On entry, stat points to a SuperLUStat_t structure. On exit, storage of panel_histo, utime and ops is freed.
