Computation Error With Optimized Apps
Urs Echternacht:
Rerunning your wu, Lysius. Using AP SSE2 application from Crunch3r's page on my T7200, openSuSE 11.1, KDE4.2. If there is something wrong with this application this host should fail as well. It's now half an hour into that wu with ca. 20 hours to go.

I have attached the WU.

Thanks, and I apologize for listing Windows archivers rather than gzip and bzip2 which would have made sense here.
Because the WU showed signals very early on the SSE2 build I changed the <dm_high> value to 1023 [1] and ran it with the Windows ap_5.03r112_SSE.exe app with my Pentium-M system. No reportable pulses were found, the best_pulses all had peak_power well below threshold.
[1] We use changes to <dm_low> (which needs to be a multiple of the <dm_chunk_large> value) and <dm_high> (which can be any value higher than <dm_low>) to make AP WUs for standalone testing which run fairly quickly. If the difference is less than the <dm_chunk_large> value the crunch time is 1/111 of a full run.

I'm also running this wu with sse2 and sse3 32bit apps from crunch3r's page. Sometime on Tuesday I should have the results.
I don't know if it is of importance or no but these 2 apps are different from the ones I, and probably also Urs, have tested during the testing phase where there was no problem found. On the other hand the 32bit sse and 64bit sse3 apps from crunch3r's page are the same with the ones we tested. I don't know what crunch3r changed.
Lysia:
Both are finished now. The SSE3-App actually took longer than the SSE2-App.
SSE3:
--- Code: ---real 1475m25.372s
user 1363m40.233s
sys 86m3.655s
--- End code ---
SSE2:
--- Code: ---real 1429m15.220s
user 1317m58.278s
sys 86m18.336s
--- End code ---

They are different. Lysius can you also run the two clients attached below?. They are the ones we've tested before release.
