A CUDA application has been released for 32 bit Windows (will run on 64 bit) and for 64 bit Linux. Below are some considerations:
- Linux version may experience a GPU slowdown while CPU is at full load. This is believed to be a CUDA/OS specific problem. Please post if you experience this.
- The GUI in windows will be less responsive while the app is running.
- Sieving/primality testing strikes at the GPU weaknesses. Therefore, the application, while the fastest at PrimeGrid, does not compare to some of the other projects where the code is better suited for the GPU's. As such, credit will be somewhat lower than what you might experience at other projects. Nevertheless, you now have one more "device" to crunch on at PrimeGrid. :) Enjoy!!!
Please post your GPU observations/questions here.
A special thanks to Gerrit Slomma (roadrunner_gs) and Bryan Little (mfl0p). Without their efforts, this would not have become a reality!!!
