STREAM version $Revision: 5.10 $
-------------------------------------------------------------
This system uses 8 bytes per array element.
-------------------------------------------------------------
Array size = 1200000000 (elements), Offset = 4 (elements)
Memory per array = 9155.3 MiB (= 8.9 GiB).
Total memory required = 27465.8 MiB (= 26.8 GiB).
Each kernel will be executed 10 times.
  The *best* time for each kernel (excluding the first iteration)
  will be used to compute the reported bandwidth.
-------------------------------------------------------------
Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 270131 microseconds.
    (= 270131 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.
