Oracle Solaris Studio Performance Library LUSolveFlops(3P) NAME LUSolveFlops - A query function that returns the floating point opera- tion count of the solve step of the SuperLU solver. SYNOPSIS #include <sunperf.h> float LUSolveFlops(SuperLUStat_t *stat); float LUSolveFlops_64(SuperLUStat_t_64 *stat); PURPOSE LUSolveFlops returns the floating point operation count in the solve step of the SuperLU solver. This information is collected and stored in a structure object 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 LUSolveFlops returns the single precision floating point value in array ops that represents the number of floating point operations performed in the solve step. ARGUMENTS SuperLUStat_t *stat (input) On entry, stat points to a SuperLUStat_t structure.
