I've no stake in the game but I think when you're months late communicating efficiently should be the least you can do.

New update!!!
The GPU primality tester works now! Finally.. Testing the first, very much unoptimized version on testnet, a HD6990 seems to be about 2x as fast as a Phenom x6 1055T. On mainnet, there's still the problem of having too few candidates left after sieving, which leads to GPU underutilization.
I'll write a better update in the morning, it's 4 AM..

https://bitcointalk.org/index.php?topic=273637.msg3008508#msg3008508Correct me if I'm wrong but how is a 100% increase on a GPU (HD6990) that is 400% more expensive than a Phenom x6 CPU an improvement in the slightest ?
Unoptimized preliminary results,, But still... any real world expectation at this time ?
