Dear Dr. McCalpin,
I would like to submit the standard STREAM result of a Supermicro AMD =
Istanbul 4-Way system.
Below is the system description and STREAM test Result.
Hope to see it being posted soon.
Best Regards.

Total memory required = 915.5 MB.
Each test is run 40 times, but only
the *best* time for each is used.

Your clock granularity/precision appears to be 1 microseconds.
Each test below will take on the order of 202721 microseconds.
(= 202721 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.
