Simon:
Hi folks,

Code Revision 2.2 'Noo? No, Ni!' of the KWSN/Lunatics.at SETI@Home optimized apps has been released.

This new revision supersedes the previously released Rev. 2.0 apps for all systems as well as the 1.41 app for Core-2 based systems.

The people responsible for this new version are, in no particular order, Josef W. Segur, Ben Herndon and Alex Kan. A great big "thank you", guys!

Thanks also to the tireless members of the prerelease test community!

Windows optimized apps (static executables, 32/64-bit compatible)

There are various different optimized apps. Please use a program like CPU-Z to find out exactly what your system supports.

Choose the first, in order, your system supports among the two lists (AMD/Intel or Intel only).


Intel-only apps (do NOT run these on AMD systems!)

Core 2 SSSE3-optimized app (Conroe, Woodcrest, Clovertown, Kentsfield, Merom, but NOT Core Solo/Duo!)
Pentium M/Core Solo SSE2-optimized app
Only use this app on Pentium M-based systems like Dothan, Banias or Core Solo/Duo (NOT Core 2 Duo!).
Pentium 4/Pentium-D SSE3-optimized app
Pentium 4 SSE2-optimized app


AMD and Intel-compatible apps
SSE2-generic optimized app
SSE-optimized app
MMX-optimized app

As always, use these apps at your own risk. A pre-edited app_info.xml has been included with all files. Please unpack the files to a temporary location using 7-Zip (get it from http://www.7-zip.org), then read Instructions.txt in the folder it creates.

An Auto-Installer for these versions will come tomorrow or the day after, along with versions including graphics.

Happy crunching!
Regards,
Simon

What are the improvements of the newest release? I've read something about C2D, so isn't there anything new for older machines ?

KarVi:
Thanks to all the programmers for their great efforts! I'm already running the SSE client on my AthlonXP, and a patched Intel "only" SSE2 on my A64.

Looking forward to seeing how much it improves my times, but it seems that the AthlonXP likes the new app. a _lot_.

Also looking forward to seing reports about if the Intel SSE2 or SSE3 is the faster one for my A64.

Furex:

As far as remember there are some rather huge improvements for this release.
They found a memory read that was happening every cycle, and found a way to reduce these reads a lot. This is the biggest improvement, and should help _all_ processors. There is also some new SSE code in the release.
The numbers I've been hearing is improvements of 20-30% and maybe even more in total crunching time. I'm not 100% sure about these numbers, my memory can be a little inconsistent  ;D , but time will tell us about the improvements.

popandbob:
Seeing about a 10-20% improvement over 2.0 so far  ;D ;D

Thanks for the time you have put into this.

I had what appears to be a slight improvement on my Dual Core Opteron by using the patched IntelSSE3 over Generic SSE2 (still gathering stats to be true). - edit: I was talking about 2.0 of course

Is there a thread detailing changes in release 2.2 ? I wasn't able to find one
