Each test below will take on the order of 58110 microseconds. (= 58110 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: 5140.0587 0.0623 0.0623 0.0624 Scale: 5136.2821 0.0625 0.0623 0.0635 Add: 5515.3437 0.0872 0.0870 0.0879 Triad: 5511.3578 0.0873 0.0871 0.0876 ------------------------------------------------------------- Solution Validates -------------------------------------------------------------
