Pre-release tester with x64 Windows & SSE3 P4 needed

[Raistmer]

to test performance of AK_v8b SSE3 x64 build.

If you have SSE3-only Intel CPU (that is P4, not Core2 or Core ), x64 Windows OS and willing to run some performance test, please, send me PM.

[The Grinch]

I can do so!
Machine-Typ:
DELL Precision 690
Dual XEON X5355
16GB FBDIMM
Windows VISTA Business x64
BOINC Manager V6.6.0 x64

Actual Seti-Clients:
ap_5.00r103_SSE3
MB_6.08_mod_VLAR_kill_CUDA

Other Projects:
Einstein@home
Rosetta

Do you need other Informations?

[edit]
I see, you need NOT Core or Core 2!
The X5355 based on Core 2 ...
My false!

[Raistmer]

I attached test case to this post.
Please, extract archive and run Knabench151.cmd file. If BOINC installed as service it will be automatically stopped and restarted after test. Else, please, don't forget to stop BOINC.
After run will be  completed, post txt file from TestDatas directory (as attachment).

The same picture - big performance fall on VHAR...

[skildude]

I'll get my X2 AMD sent in tonight when I get home from work

[The Grinch]

Here are my result

LoL, and that one shows VHAR Boost 

[The Grinch]

And i do not stops my normal work!
Only BOINC was closed.

No idea why on XEON VHAR gets boost ...

[Raistmer]

That's weird... The same app and >3% difference...

I saw that ... I suspect those dodgy OS delayed writes again.  I may be wrong about that, but haven't thought of a completely foolproof way to eliminate that variation ... perhaps a custom copy command that issues a flush before close of the destination file ?

[Raistmer]

Well, it's CPU time now, not elapsed one.....

[Jason G]

Hmmm, not even wisdom generation to consider ... I wonder, will think about some possible tests to see if I can identify such discrepancy on my system or not.

[skildude]

and heres my x2 data

[Raistmer]

Ok, thanks.
All AMD results confirm that this SSE3 x64 build not for AMD hosts - too slow on VHARs.
