Spiccioli, some blocks don't appear in logs because they were stale as P2Pool shares when they were found, and so weren't broadcast.
Thanks forrestv, It seems we just found a third block, 16:40 GMT+1, but this one has not reached my wallet (yet)?!? 2012-02-08 14:59:09.241492 GOT BLOCK FROM PEER! Passing to bitcoind! c588846d bitcoin: 8acd68a3104ef43befea3fa896c91c15718b428faacb63775ca

Is this because bitcoin network rejected it? Regards. spiccioli. |

Hmm - I'm not sure if I'm just misreading that or is he getting about 1/4 (or less) of expected since the 4th 1200Mh/s is (current difficulty) ~0.8 BTC a day. Was over on the 1st and 2nd by a bit (but zero on the 3rd fixed that  ) So overall been quite under expectation. I guess that's just luck? You'd need some overall share difficulty and share count to determine what's going on. Kano, you're reading right, with 750MHs I'm receiving 0.15-0.20/day instead of 0.50-0.60 I was gettin on a PPS pool :/ spiccioli. |

with latest cgminer (2.2.1) using dynamic intensity forces a single therad per GPU, so I've set it to dynamic right now, let's see what happens.
Hi Guys, after a _long_ weekend I'm now able to mine for p2pool correctly  I've made several changes and I don't know which one was the good one (or ones), so I list them here: - installed ntpd, xubuntu does not install it by default, and my time was 4 seconds behind correct time, this did not give any problems with other pools, but maybe p2p is time-sensitive
- started cgminer with -g 1, I was setting intensity to default from cgminer menu when started, but maybe it is not the same thing since this way just a single thread is created per GPU
- started cgminer with --submit-stale as per forum message which states that current cgminer 2.2.1 needs it when running with p2pool
- pointed my miner to my p2pool pc (which is at work, while miner at home) using office IP instead of symbolic-name because symbolic name has a very short TTL and maybe miner was spending time to resolve it
Anyway, right now I've been mining for more than a day, with just three DEAD ON ARRIVAL shares and 65 good ones Regards. spiccioli. |

Normally you will see 'LONGPOLL requested work restart..' every couple of seconds with p2pool. If you're not seeing that, it might be this long polling issue. I'd try with just one pool configured.
Second thing I'd look at is if the host running your p2pool daemon is not too overloaded.
eja, I see them and, no, the host with p2pool is a 3GhZ PentiumD/HT pc with xubuntu running just p2pool and bitcoind. regards. spiccioli. |

spiccioli, try cgminer with only 1 thread, it's in the config file. Let us know if it makes a difference. thirdlight, with latest cgminer (2.2.1) using dynamic intensity forces a single therad per GPU, so I've set it to dynamic right now, let's see what happens. regards. spiccioli. |

Any idea?
What version of p2pool are you running? That looks like miner output. What does your p2pool output look like? As has been said many times, stales in p2pool are higher than a traditional pool Red Emerald, that is p2pool (I'm using latest) log file filtered for "GOT SHARE" lines. I uderstad higher, but here they're mostly dead and it seems other people on p2pool have a few dead shares even with thousands good ones received. Look, I've just restarted p2pool 08:59:19.034126 Average time between blocks: 0.40 days
08:59:19.034604 Pool stales: 10% Own: 67±33% Own efficiency: 37±37%

something is wrong, isn't it? most are dead, and what does that "age" field really mean? I'm using latest cgminer 2.2.1 on my miner, with I 7 (intensity) and just p2pool, I have a failover pool, to be honest, but with inside cgminer.conf. Any idea? best regards. spiccioli. |

twmz,
there is one thing in my setup which is not "standard" and this is the fact that my miner runs from an usb key so I have the miner at home and p2pool and bitcoind at work, so there is some more latency, I suspect.
I don't have my numbers at hand, but I have a lot less shares (I have less MHs) and a lot more orphans and dead shares.
spiccioli.

Ok I'll check next time I mine. The blue part is the part that is reporting me such awful numbers (16-23 % stales). Efficiency was 87% (plus/minus a number I don't recall)
The blue and the red parts are showing the same information in different ways: Total submitted shares: 180 valid + 8 orphan + 5 dead = 193. Stale % = (8 orphan + 5 dead) / 193 total = 0.067 = 6.7% But it is the red part that tells you what kind of problem you have (orphan vs dead). Of course, these numbers are only useful after p2pool has been running for a few days. They start out at zero everytime you restart p2pool and for the first day or two, randomness will make it hard to know what the real pattern is. twmz, there is one thing in my setup which is not "standard" and this is the fact that my miner runs from an usb key so I have the miner at home and p2pool and bitcoind at work, so there is some more latency, I suspect.

Finally, I have moved all of my 500 MH/s to P2pool from deepbit. It feels good.
I've been mining on P2P with 760MHs for four days now, but I'm mining just one third, more or less, of what I was getting when I was on a PPS pool. I do understand that there is variance, but now I need a day where I mine 8 times as much just to be on par with my previous PPS payout. I don't think I'll see such a day soon, though. Then rounds, they should last 10 seconds, but they're often a lot faster, see: [2012-02-01 18:44:50] LONGPOLL requested work restart, waiting on fresh work

here we have 2, 2, 9, 5, 19, 5, 14, 4, 3, 4, 12, 3, 9, 10, 7 seconds rounds, there are a lot of 2 and 3 seconds long rounds. I see that a few months ago rounds went from 5 to 10 seconds, so I'm asking wouldn't it be better to have 1 minute long rounds? Can fast rounds give high MHs miners an advantage since they can exhaust the nonce range even in a very short round? I'll keep my miner on P2P for a few more days, but if rewards keep being so scarce I'll have go back to a PPS pool or otherwise I feel like I'm just wasting power  regards. spiccioli. |

Not sure, but the max the power supply can draw is 250W, so less than that.
Azelphur, thinking a little more about this it seems that the card doesn't have power cables, so per pci-e specs it should use a maximum of 75W (from pci-e slot), but 3.6 GHs for 75W is too good to be true :/ btw, you say that OP has such a card mining on your private pool, can you or the OP give any proof of this claim? spiccioli. |
|
|
|
Azelphur, do you know how much power does it use? three thousand bucks is not so pricey given a 7970 is around 550 USD and gives around 600MHs. if this one is 6x a 7970 in MHs but uses 1/5th of that power it would be a good card to mine on. best regards. spiccioli |

Additionally, I was thinking that if people would like to "chip in" and buy a DE4 among a couple of people, I could help arrange that for people. I've been speaking to Terasic about possible deals. You can email me if youre interested in buying part of a DE4 (that is to say, part of 3.6GH/s+). Just a thought, I haven't worked out logistics but this might be a good way to do it..? I'd just make the arrangements for y'all to meet, maybe somewhere to run it from since DE4s require subscription software to program. I dunno, again, just thoughts.
wondermine, which version of the DE4 board are you referring to? and how much does it consume? regards. spiccioli |

Thanks!
EDIT: If it's not showing your country at all then I'll need to communicate to Bit-pay about it. Which country is it not showing?
Gosh, just ordered a copy, I'm from Italy, my country was not shown either, but I thought it was just a "cosmetic" problem since there was a drop down menu to input one's country. Tell me please if I have to PM you my address! Regards. spiccioli. |

I think this would be a great thing to have so we really do go after the whole world literally. Does anyone know if we've touched every language in explaining bitcoin?
Hi bitstarter, there is an ongoing effort to translate the original Satoshi's paper in every language, see http://crowdin.net/project/bitcoin/inviteRegards. spiccioli |
