Hello,

here you can download an optimized version for Intel Sandybridge processors.
We expect a 10% speed increase.

How to install the app:

2) Shutdown Boinc
3) Download the app and extract the content into projects/www.rechenkraft.net_yoyo
4) start boinc
5) download a OddWeirdSearch wu.

If it is faster on Sandybridge then it should be faster on IvyBridge and Haswell as well, right?

I assume, yes.

On Nehalem it does not work (Illegal Instruction), so I guess AVX is required.

If you're not sure, just start it standalone before you copy it into the project folder, then check stderr.txt for error messages

Under Haswell Reloaded, it deleted all my workunits for every Yoyo project and the log says "don't need" when I try "Update" or "Reset"
