I invite you to join the GFN Challenge during the anniversary of Pierre de Fermat's death on January 12th, 1665. This will be a five day challenge from January 9th through the 13th in the hopes of finding new GFN primes. There are four PRPNet servers running GFN searches. GFN32768 has the highest probability of finding a prime, but GFN524288 could yield a prime over 2,000,000 decimal digits in size.

GFN262144 and GFN524288 can be crunched on a CUDA-capable GPU, making this one of the few challenges where you can put your GPU to good use!

With llrCUDA, one can also do some of the other projects, but I agree that geneferCUDA utilized the GPU better than llrCUDA.

All we need is an OpenCL implementation of genefer and llr.

I was thinking that the range on the GFN262 port had gotten to high and that GPU for that port was no longer working. From this post it looks like it might have changed and I missed that little note?

All we need is an OpenCL implementation of genefer and llr.

Only a CUDA-capable GPU is not enough for llrCUDA and maybe geneferCUDA. You need a DP-capable GPU.

Please no OpenCL implementation for genefer or llr. What we need are CAL implementations for all apps.
Have a look onto the runtimes of TPSsieve on the AMD HD5800 series. The runtimes are ridiculous in comparison to the nVidia GT9000 series and even more in comparison to the nVidia GT400/500 series.
