CUDA for prime number search
Pepi:
Since there is coders that understand coding and cuda very well, I ask anyone of you can you spent a little of your time and look in source code of this app and optimized it for better performance.
For now CUDA LLR is in average 2-3 times faster then one core of average cpu ( speed 3GHz) ( on my GTX 560 Ti) : Since you guys increase speed in optimized S@H app many times, I assume that you can make similar increase in speed also in this app.
So for now I will wait will anyone will even answer to this post :)
Thanks for reading.

PrimeGrid ? Is that the project you're referring to ? Another user/developer (Heinz) has expressed interest in that one. If he's interested in looking into optimisation for that I'll be happy to give him some hints / guidance.

Collatz would be nice as well, maybe figure out what needs to be added to bring into compliance with the BOINC api.
I just wish I understood coding.

Doesn't stop the rest of us :D What level are the mental barriers at ?

Yes, Primegrid is that project. Since source code is very small I think you will find any "problems" really fast. Only "problem" is that app is 64 bit :(
You need to have cufft64_32_16.dll and cudart64_32_16.dll in same directory as llrcuda.exe ( attached as llrcuda.rar)
Source code is also attached in second archive.
Command is (example) llrcuda.exe -d -q"46157*2^698207+1"
Thanks for any help Jason!
