Default Primecoin - Cunningham Chains

From Bitcointalk

Quote:
Thanks for your support in our prerelease thread (https://bitcointalk.org/index.php?topic=245953.0)

Primecoin will be released shortly.

http://primecoin.org

Design paper published today at
http://ppcoin.org/static/primecoin-paper.pdf

Source code will be available at:
https://github.com/primecoin/primecoin

Official Build (Windows + Linux, primecoind & primecoin-qt) will be available at:
https://sourceforge.net/projects/primecoin/files/

Release Time is 2013 July 7, 18:00 UTC

Update:

Windows and linux builds have been released.
Source code uploaded.

Blockchain is now up and running.

Mining with Qt: debug window -> console -> type 'setgenerate true' or 'setgenerate true <thread-limit>'
I prefer to download the client here https://bitcointalk.org/index.php?to...425#msg2724425



Is anyone here able to write some opencl or cuda-applications to cover this new coin and to explore more cunningham chains? :)



E: forgot to mention that there are exchanges where you can change Primecoins vs Bitcoins https://mcxnow.com/exchange/XPM

Sieving for CCs (either kind) is easy with NewPGen (or similar), followed by (PR)P pretesting for the initial seed primes, followed by offline (very quick) testing of the few candidate chains. This is not very different from the PGrid's SG/twin search; check if they use GPUs of either kind for SG? - and the answer is no.

Now, sieving may be accelerated (ask rogue), but it doesn't seem to be the bottleneck; most of the project wall time with be in the PRP/LLR pretesting a la LLRcuda and the going will be tough; afaik, it runs (at least with small k values)... but in contrast with other applications not 102..3 times faster, but only O(1) times faster than a CPU. Ask msft and VBcurtis.
