Optimized SETI@HOME Apps, INfo, Downlads

If you already have BOINC installed just attach to:
http://setiathome.berkeley.edu
Determine which instructions your CPU supports
then download optimized SETI program from:
http://lunatics.kwsn.net/index.php
Installation of the optimized app is simple.
Copy all files in the "Files to install" directory to your BOINC\projects\setiathome.berkeley.edu folder.
There is a file called "app_info.xml" included that will make BOINC use this app automatically.
To use it, exit and re-open the BOINC Manager if you're running it in single-user mode, or re-start the service if you're using service mode.
That's it, you're done! You can open your task manager to see that it's really the new optimized app crunching your WUs.
BOINC will tell you that it found app_info.xml and is using an "anonymous platform".
You can find updates, instructions and source code here:

when running the optimized version it will cut the time to crunch WUs in half. 5-6 hours for a 60pt WU down to 2 hours. AMD 3000+ 754

Now a few words about optimization. Many of you want to "optimize" your system. There has been some confusion about what parts to optimize for best results, since there are optimizations for the Boinc client, and the science apps.
The optimized boinc clients *may* help speed a tiny amount by switching tasks a little tiny bit faster, etc. however they are only useful if they contain features that are desired but not available in the original client.
The real gain in crunching speed comes from an optimized "application". These are applications that have been optimized to take advantage of special instruction sets available on most cpu's (computer chips). These may be mmx, sse, sse2, sse3, etc. Each offers different specialized commands that can be used to speed up crunching. In the old Seti application (the ver. 4.xx series) there was no optimization in the default application at all, so anything was an improvement. Speed increases of up to 300% and more were seen using optimized applications. The new Enhanced Seti application is already highly optimized, so you will not see nearly as large of a speed boost using the enhanced apps, but you will get some benefit. While I've not kept track of the speeds, I've seen claims of between 20 and 40% speed increases using the proper optimized application for your computer chip set.
