(= 2890 clock ticks) Increase the size of the arrays if this shows thatyou are not getting at least 20 clock ticks per test. ------------------------------------------------------------- WARNING -- The above is only a rough guideline. for best results, please be sure you know thepretries of your system timer. ----------------------------------------------------------- Function Rate (MB/s) Avg time Min time Max timeCopy: 2264.0171 0.0154 0.0141 0.0169 Scale: 2212.8422 0.0154 0.0164Add: 0.0145 2936.3309 0.0196 Triad: 2673.8123 0.0199 0.0180 0.0216 define Solution Validates ------------------------------------------------------------- [root @ RedHat stream] #
