Printing one line per active thread.... ------------------------------------------------------------- Your clock granularity/precision appears to be 1 microseconds. Each test below will take on the order of 52904 microseconds. (= 52904 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: 5323.0375 0.0602 0.0601 0.0602 Scale: 5318.7975 0.0604 0.0602 0.0613 Add: 5721.2283 0.0841 0.0839 0.0842 Triad: 5711.0200 0.0842 0.0840 0.0849 ------------------------------------------------------------- Solution Validates -------------------------------------------------------------
