got my first block on hp10 with stock settings after 3 days, mining on a core i3 with -1 idle priority (usually, when I leave the computer, I find a block). but i'm keeping my PC turned on 24/7, not doing really well.

|
|
|
after 30 minutes, it cleared up, and downloaded the remaining blocks, just needed to be patient to discover more nodes

I guess that the 'heart' of cryptocurrency, they are just as volatile as forex (still more volatile than forex because it doesn't depend on economies).

testnet never seem to sync, connected only to 1 node, what can I do? forever stuck on 16 block remaining

is getblocktemplate ever coming to PPCoin?
Yes it is scheduled for v0.4. QFTT  |

Does the version hp9 takes advantage of AVX on core i processors? if not, hp10 will include those?
Any software can use AVX if you compile it yourself with a decent compiler. In a precompiled release, it's possible to have separate code paths with such optimizations, but I think such releases are unlikely at this point. AVX is just one technological improvement among others, like the numerous SSE iterations, and it would take dozens of different binaries to cover all possible optimizations. Also, besides the instruction set, there are optimizations for scheduling and cache sizes. Speaking of which, Primecoin performance is apparently sensitive to L1 cache; there are options like sievesize that may be optimized for a given cache size without recompiling. In general, though, if you want something optimized for your particular machine, you need to compile it yourself. alright, I will try some switches, thanks. just asked because there are some ASM includes that are specific to AVX, and they perform really really well and the opcode can be easily identified (and skipped, in code if not found) and used. scrypt and sha256 already got those optimized versions. |

Found two blocks on a i3 380M using 4 threads and low process priority on hp9, with 2 hours between each block. it's completely random, but it certainly works.

I'm finishing a custom mining pool with a lot of new features that other pools doesn't have, coded from scratch, that I need to decide where would be the best geographical locations to focus the first servers on. It got an improved DDoS protection, and fault tolerant tecnology with no single point of failure, but the less latency for the majority of the users, the better.
Depends on the reliability of the server hosts. I'd rather have good uptime than a short latency. yeah, uptime is the most important part indeed. I'll be using Amazon with multiple load balancers, either HAProxy or geo based ELB ones from AWS itself. Since the code is being thoroughly tested for maximum stability, the only remaining issue would be latency (that depends more on miners locations than on my code)  |

Is this up yet? I'll create a poolers CPU miner fork for Primecoin if it is
|
|
|
|
|
ah nice, well I'll give it a shot, thanks

I was noticing, Primecoin (XPM) is drawing attention because of it's uniqueness. But there isn't any 'generic' miner capable of working with stratum so far, why is that? If there's interest from the general public, I can modify poolers CPU miner to accept prime mining, along with stratum support, so everyone can create a pool for mining primecoin. Of course, it will be open source  |

Hmm, on ypool block statistics ( http://ypool.net/stats.php?a=bd&nr=3981 ) the user mumusv6miner 15517 4521.7 0.69676
how he got 15k shares in one block that took less than 2 minutes to be found? he's have the biggest share count in ypools... something special of his seting？？ Fishy? v4mumusminer 18083 5000.9 0.755724 mumusv6miner 14510 4928.9 0.714749 Remember, shares count for 40 blocks... Yes, but no one else in the pool is getting anywhere near those stats. That is a serious amount of horse power to get that kind of figure. The closest is about 11000, but those two combined are 32000! Looks out of place in the list of other miners. Maybe I'm just being paranoid. Maybe there is a GPU version out there? Maybe he owns a server farm? Maybe we are all mining for him? Maybe it isn't even him? Maybe I should shut up lol. How effing stupid are you? HOW are we mining for him??? In a quick look, he's found 9 out of last 30 blocks. 1.41-1.52 average per block x 30 blocks = 42.3-45.6 XPM. If he'd been mining solo that'd be well over 90! Sure looks to me like HE's mining for US. (Prob shouldn't tell him, he'll quit the pool and then where are we?) So what if he's running a VPS farm with 400 CPUs? I know I am close to break-even, have earned 97XPM through the pool and my stats say I've found 9 blocks. So I would have been bettter off if I'd been solo, but I'd not have had a constant income. It's a trade off. Thank you for the nice comments, I meant no ill will to Mumus or anyone else by my comments, I was theorising and you obviously missed my point. There is no escaping that those stats do stand out. The following is how sad and stupid I am, How do we know that the compiled version that we have all downloaded contains the same source code as what has been posted on github? Unless someone has taken the time to disassemble it? Then we don't. So in theory, and I am not suggest this is the case, there could be some code in the miner we are all running that submits the odd share here or there to an account other than the one specified when you run it. The odd share here or there times a couple of thousand miners? You do the maths. This is how it is potentially possible that we are mining for him. What a ridiculously stupid idea though. Again I was theorising around the possibilities of that vast power advantage those two users appear to have over everyone else. It may not even be Mumus, and in which case the theory above is completely null and void. Again I would like to apologise if I have caused offense. I am no troll and that was not my intention. that's exactly what I thought... it's a proprietary protocol and a proprietary miner, open sourced, yes, but we have no idea if the compiled version is the open source one... that discrepancy in the share count is eye catching. |

How is a temporal (per user) wallet is created and "destroyed"? I couldn't find much info on this. Is it ephemeral, as in, are stored in a database without any real bitcoin "value" and sent from the hot wallet / cold storage, that then, is dealt directly using bitcoin?

Well, block payments just dropped below 11 and difficulty passed 9.54
It's amazing how much a software update and better parameters can get you.
On that note, I'm starting to think the chains/day measurement is becoming less accurate. Either that or I've been quite unlucky.
It seems to not be accurate for me - I haven't gotten any blocks since the 25th (other than an orphan on the 25th) on my desktop though so I feel it's hard to tell. Then again my sister got three blocks on saturday with the same cpu... It seems like it's a rough average that was accurate when it was added but is slowly becoming less useful for judging how often you might get a block from my experiences. One major misconception on this coin is people think it acts like any other coin out there... in one way it does, but for the most part it doesn't. Bitcoin, Litecoin, etc, all use a hash. Since the hash needed is random, it takes time to find. This is the only area where primecoin is like the others, in that it is a random chance to get the right variable to find a prime. Where primecoin diverges is that it can never reuse a number already found. Bitcoin and Namecoin can use the same hash and be 'merged mined', primecoin alone can never be merge mined. The basis behind blocks is finding Cunningham Chains of length N where N is the difficulty rating. What does this mean? The smallest known length 9 chains are:85864769 and 857095381 (1st and 2nd kind). The proof of work on this coin is such that once a prime chain has been found, it cannot be reused. So each prime found means the one less prime that can be found. Look at the records primecoin has found in length 9 chains: 2030793138184474269420052163338592688212588454185304749794006580858788424425799 69*179#-1 is 151 digits long! In a way, the nice thing on this is that as time goes by and the length of these primes gets up into the 1000+ digit range, difficulty will start coming down as they become harder to find and we'll start finding larger 8 chains and larger 7 chains. Therefore the metric for finding blocks is ever changing, you can't count on what works today being the best thing to do in 2 weeks time as well. This is an ever changing coin and people really need to start thinking outside the box. That's really interesting info, I couldn't figure out how the block hashes were determined in Primecoin. This shows Primecoin to have a really bright future! |

Does anyone have any idea how the pool miners currently compare to solo mining (assuming using a large enough number of machines to make the test fare)? The HP solo miner was at one stage considerably better than the pool miner, but don't know whether that is still the case or not.
1 day on pool = 12XPM (24 CPU threads, 60GB RAM) 1 day on solo mining = 34XPM (8 threads, 60GB RAM) make your conclusions btw I'm doing both at the same time (32 cores in total), so one complements the other in 2 hours: ---- New Block: 97587 - Diff: 9.310326 / 6.000000
