------------------------------------------------------------- STREAM version $Revision: 5.9 $ ------------------------------------------------------------- This system uses 8 bytes per DOUBLE PRECISION word. ------------------------------------------------------------- Array size = 20000000, Offset = 0 Total memory required = 457.8 MB. Each test is run 20 times, but only the *best* time for each is used. ------------------------------------------------------------- Number of Threads requested = 1 ------------------------------------------------------------- Printing one line per active thread.... ------------------------------------------------------------- Your clock granularity/precision appears to be 1 microseconds. Each test below will take on the order of 21547 microseconds. (= 21547 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: 10213.8948 0.0323 0.0313 0.0388 Scale: 10187.2265 0.0327 0.0314 0.0392 Add: 11015.2372 0.0452 0.0436 0.0540 Triad: 10913.0751 0.0453 0.0440 0.0549 ------------------------------------------------------------- Solution Validates -------------------------------------------------------------
