STREAM version $Revision: 5.9 $

-------------------------------------------------------------

This system uses 8 bytes per DOUBLE PRECISION word.

-------------------------------------------------------------

Array size = 2000000, Offset = 0

Total memory required = 45.8 MB.

Each test is run 10 times, but only

the *best* time for each is used.

-------------------------------------------------------------

Printing one line per active thread....

-------------------------------------------------------------

Your clock granularity/precision appears to be 6 microseconds.

Each test below will take on the order of 17340 microseconds.

   (= 2890 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.
