Each test below will take on the order of 2438 microseconds. (= 1219 clock ticks) Increase the size of the arrays if this shows that you 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 the precision of your system timer. ------------------------------------------------------------- Function Rate (MB/s) Avg time Min time Max time Copy: 14414.9638 0.0022 0.0022 0.0022 Scale: 14356.3727 0.0022 0.0022 0.0022 Add: 14072.8780 0.0034 0.0034 0.0034 Triad: 14097.5136 0.0034 0.0034 0.0034 ------------------------------------------------------------- Solution Validates -------------------------------------------------------------
