STREAM version $Revision: 5.10 $
-------------------------------------------------------------
This system uses 8 bytes per array element.
-------------------------------------------------------------
Array size = 53687091200 (elements), Offset = 6 (elements)
Memory per array = 409600.0 MiB (= 400.0 GiB).
Total memory required = 1228800.0 MiB (= 1200.0 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 1508336 microseconds.
    (= 1508336 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.
