Hi John,
I've run your stream test and wanted to post my results. I don't see a way
to post them, so I'm emailing them to you.
If there is a way and i've missed it, please let me know.
Here are the specs of the box I ran it on, and the results.
Thanks much,
Phyllis

-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 999936
Total memory required = 24.9 MB.
Each test is run 10 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 8890 microseconds.
(= 8890 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.
