These STREAM results have been approved for publication.
They were obtained on a Unisys Corporation ES7000 Orion 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 Orion
130 Server contained eight (8) 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. In this
case we set N=12,000,000.
STREAM EDITORS NOTE: THE "STYLE" INDICATED BELOW IS IMPORTANT. THIS "STYLE" INDICATES AN 8 PROCESSOR SYSTEM CONFIGURED WITH TWO PROCESSORS ON EACH OF FOUR BUSSES. THE SYSTEM IS ALSO AVAILABLE IN A CONFIGURATION WITH FOUR PROCESSORS ON EACH OF TWO BUSSES. THE LATTER CONFIGURATION WOULD DELIVER SIGNIFICANTLY LOWER STREAM RESULTS. THESE RESULTS ARE LISTED AS "STANDARD" RESULTS EVEN THOUGH THEY FIT INTO THE "PARTIALLY POPULATED" CATEGORY BECAUSE THE VENDOR HAS STATED THAT THE SYSTEM IS ORDERABLE IN THIS EXACT CONFIGURATION.
Detailed Results:
8X Unisys Corporation ES7000 Orion 130 Server (Style ES7005263-GS)
-------------------------------------------------------------
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 9628 microseconds.
(= 9628 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.
