CUDA_V12_app
Sutaru Tsureku:
In past with Crunch3r's BOINC V6.1.0 (mod of stock V5.10.1x) and CPU-affinity I saw a crunching speed up of ~ 1 - 2 % with MB WUs.
Intel Core2 Extreme QX6700.
This is a 2x DUO-CPU. 2x shared L2-Cache. So cache miss can happen.
Now with the current available Quad-CPUs which have a L2-Cache/CPU-Core this Cache miss can happen much more.
It would be nice to have again a Truxoft- or Crunch3r- BOINC mod with this.

You could test Raistmers App as he asked you to do. What you could, report would mean he moves it ahead or it truly dead. It is your choice.
It is just that simple... BS Aside.

Don't you think it's time to stop with this?
I think enough is ENOUGH. >:(
Let it be!
