I am having a bit of a hard time finding this out but how many XPM block and what is the supply rate =F(Hash)
also notice 3 exchanges carry XPM already!!!
quite an achievement
it will probably be on BTC-e next
XPM rewards lower with higher difficulty, right now it's in the low end of 15.xx, difficulty hasn't reached +1 yet but it's close "blocks" : 29776, "moneysupply" : 502896.70000000, |

Someone has to determine the miner situation. Which one works best for intel and AMD, Sandy, Ivy, Haswell, FX etc.
No, someone doesn't have to. It might be kinda nice, but there is certainly no obligation, much less a mandate, on anyone to do so. +1, nicely said. Indeed It's right up there with the difference between "want" and "need" |

Are you sure you're on Ivy? Because 0710-avx is an mtune build while 0712v2 will only work on Ivy Bridge cpus. Weird. I'm getting 50-100 higher PPS on your Sandy+Ivy V2 build than your Ivy only V2 build? Either way they are like the V2 Rockets of QT clients right now! People need to donate to anonppcoin. He (assuming) put a lot of hard work into building. There's several benchmarks on www.phoronix.com on newer versions of gcc with ivy bridge support bench-marked against older versions. From my own experience Gcc4.8 with core-avx-i was a performace loss regardless of the software it compiled compained too 4.6 with corei7-avx, I can only speak for Linux on that account, as always your mileage may vary. |

Please note primespersecond is not an accurate measure of actual performance. It has some correlations but if sieve round is reduced too short you could see inflated pps but not really faster performance. Only block rate is an accurate measure of true performance.
Understood. Now we just need someone to build a CUDA implementation and release it to the public before some basement hacker gets one working and runs it for himself. The theoretical speed of CUDA Mersenne solving is something like 1000x faster then CPU. A single SLI Nvidia rig could throw 25 million PPS if optimized on CUDA. Gotta sort out the API before that |

I'm not a gpu farmer but I think its better to have people that invested in crypto reap the benefit than botnet owners. I like cpu mining but once a coin becomes big botnets step in. So i see gpu mining as good progression.
Is it really possible that somebody has it's cores maxed to 100% and not noticing he has a bot? Bot-nets are dangerous for stealing passwords, but will they be dangerous for mass-mining? Yes, some botnets mine in the shadows of masses like litecoin. A large increase there is not noticed like on smaller coins. Plus the botnets are used for DDOSing the exchanges. So they are very harmful to the crypto community. Saying "the botnets" are used for DDoSing the exchanges is ignorant. I personally know a botnet owner who would never DDoS anything. Fixed. |

We maybe going at this from the wrong angle.
Luke Jr claims that BfgMiner has a 10-20x mining performance improvement over primecoind. If that is really true, it seems like most of the performance improvement should be in the prime implementation since both programs use CPU mining.
It should be feasible to take the prime implementation from BfgMiner and incorporate that into primecoind to get a similar performance improvement out of primecoind and avoid the getwork/gbt issue altogether...
Trouble with that is pools are going tobe needed sooner or later |

Sweet  testing now ...I think I removed all the extra printf statements I used to test it out, but let me know if your ~/.primecoin/debug.log file explodes in size... Its recompiling on 20 nodes now. Lets see how it runs  First impression is 1200PPs to 2000PPS 20 nodes, good lord! is that 2000 pps per node? 20x2000PPS right now yes. Have 30 more runnning. Might update them if blocking works lmao, now we know where all the blocks are going  |

Anyone know if the primecoin testnet is down? If it's not, any chance of getting some testnet nodes posted?
The reason why I'm asking is because I've modified the original algorithm and it's currently running on my core i7 desktop at 1840(40) pps whereas the latest build runs at 1030(60) pps. I'd like to share this with everyone, but I need to make sure that it will actually find blocks and I need access to the testnet to make sure it's actually working...
Oh, and the same compiled code runs on my Core 2 Duo laptop (T9300) at 400-600 pps
As soon as I get access to testnet or whenever this code finds a block on the real network I'll send a pull request to the github repository

Some of my observations:
The average block generating speed for the first 1000 blocks was about 44s;
The average block generating speed right now (around block 21400) is about 8.8s;
Considering difficulty and other factor, I calculated the total mining power increases 72 times. If we assume the algorithm optimizing provide 7 fold improvement, then I guess the miner base increased by a factor of 10 since start.
Just redownloaded the block chain and watched the logs fly by, lots of orphans started too show up since this morning. Must be someone out there figured out an external miner? or people using DigitalOcean(VPS) |

This got me past the crash on launch anyways. Not sure if I was missing the "=" after --algo or what. Now I can see "new blocks" arriving, although they don't line up with when I see new blocks in QT debug terminal. Difficulty is being reported as 0, could be an unimplemented piece of the code or could be an actual problem.  Doubtful that it's actually functional. You need to pass it a --scan-time 1, that way it will register new blocks faster (necessary for those short intervals we have) It seems to pass whatever it finds, though, no proof-of-work check implemented yet as it seems. So far all my block candidates it found on testnet were rejected(by primecoind). No block candidates on production yet. I've gotten the same results as you, I even went as far as too modify coindbase-addr too accept the addresses |

Was tired of trying to add immature blocks up so heres some dirty bash too get it done, I'm sure someone has a much better solution. echo `./primecoind listtransactions "" 1000 | grep -A1 category | grep -A1 'immature\|generate' | grep amount | awk -F" " '{print $3}' | awk -F, '{printf "%s +",$1}'` 0 | bc
Edit: this doesn't account for sent. If I'm not mistaken, the balance command alone (i.e. './primecoind balance') will give you the total of only mature blocks, but if you include the account parameter (i.e. './primecoind balance ""'), it will give you the total of all blocks, both mature and immature. All you have to do is subtract to see the immature balance alone, if I understand correctly what you are trying to do. lol I did say some would have a better solution, never accured to me too use "" in getbalance, touche. |

If it was set slower many miners would quit.
