Here's a test run on my Athlon64 3500+ 2.2GHz single core with an ATI Radeon X800RX.

I've attached the stdout, stderr and result.sah for you - by the way, are you using a -9 (Result overflow) WU on purpose so it stays short? May not be the best way to test with, but I'm not sure. Maybe Joe can tell.

Finished pretty quickly even with such a comparatively slow card.

Regards,
Simon.

Simon -> "Finished pretty quickly even with such a comparatively slow card."

How quick is quick in this case?

I'll have to do another run to be sure.

Here's another run from my laptop in the meantime - 3.06 GHz P4 mobile, 1GB DDR333, Radeon 9600 Pro mobile.

Regards,
Simon.

<edit>The run on the A64 took 3 Minutes 6 seconds, on the laptop more than 10 minutes (estimated). CPU usage on both hosts was 100%, both 32 bit XP.</edit>

The app itself setiathome.xxxx.exe consumed about 6 minutes in cputime in the processmeter in windows.. 6 minutes and 2 seconds then it closes up. (The app itself never consumed more than 50% , and systemprocess fiddled up and down from 12-42% aprox).. The cpu was never used 100% on both cores!

Core2Duo (Overclocked to 3.3 ghz), Vista X64, 8800GTX (Orig clocks)

File included with stderr etc..

P.S Damn! (That was fast times on the A64 though, wonder if Vista X64 does something) Nice..

I compared the result.sah file from both your hosts and they produce the same result, mine differ alot in all values compared to yours from the A64 and the laptop ..

Seems really like a Vista or x64 issue in this case, really odd indeed..

Update:  I tried that particular W/U with a regular Kwsn 2.2B SSSE3 client, it took about 3 minutes and completed without errors (The -9 error) so the code needs some polishing but it completes though..

completed in 4 minutes 30 seconds.

result.sah and stderr attatched

full 100 % usage of cpu is only on older cards and a single core CPU

[Neoman]

System: E6600@3.6G 8800GTX(core612/mem2000) under Vista64
The cpu usage was 62% and it took more than 10 minutes to complete i guess.

resuilt.sah and stderr attached.

Pentium D945 @ 3.6Ghz, Nvidia 7950GT 512MB oc'ed edition, Vista x64 Ultimate with just about everything turned off for the run.

Didn't get stuck like did last time which is brilliant to see. CPU usage through first part about 25-65% all together (sorry didin't take note of cpu on the app alone) and ~22% through second half for just the app itself. 
Took something like 10 minutes for me too but still great to see working. Incredible work.
