These STREAM results have been approved for publication.
They were obtained on a Unisys Corporation ES7000 Aries 130 Server running
SCO Linux Server 4.0 for Itanium Processor Family. The system was configured
with 64 GB RAM, consisting of four 16 GB memory features. The ES7000 Aries
130 Server contained sixteen (16) 900 MHz Itanium 2 processors each with 1.5
MB L3 cache. These are submitted as "standard" results. The arrays were
sized to each be at least 4x the size of the L3 cache in each system, so
N=12,000,000.
Detailed Results:
16X Unisys Corporation ES7000 Aries 130 Server
-------------------------------------------------------------
This system uses 8 bytes per DOUBLE PRECISION word.
-------------------------------------------------------------
Array size = 11999232, Offset = 1280
Total memory required = 274.6 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 9608 microseconds.
(= 9608 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.
