Each test below will take on the order of 54876 microseconds. (= 54876 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: 4994.5383 0.0641 0.0641 0.0641 Scale: 4989.2284 0.0642 0.0641 0.0643 Add: 5334.6386 0.0901 0.0900 0.0902 Triad: 5312.2575 0.0905 0.0904 0.0907 ------------------------------------------------------------- Solution Validates -------------------------------------------------------------
