For those of you dissing on the multiport, I made over 0.05 BTC last night just on PXC. That's almost a full day's worth of what dustcoin says that I should be making if I was mining LTC directly, in about 10 hours.
We're not dissing the multiport (at least I'm not). Just drawing your attention to some things so you know where to improve  Seriously, you've done a great job so far and you've got my support. I will stay on your pool for the long run. My statement was kind of tongue-in-cheek. I do appreciate the constructive comments. |

Hello all, I have a PPLNS and multipool:7777 question. PPLNS is designed so miners have to mine a specific coin for an extended period of time to be profitable. However, when using port 7777 the coin being mined is constantly changing. How can this be profitable ? It actually sounds like the least profitable method if constantly switching. Am I missing something ? Thanks.
PPLNS is actually designed so that miners who mined closer to when a block is found are paid, avoiding the problem of pool hopping where people hop on to mine right after a block is found (which would be the beginning of a new round with a proportional system). We use time-based PPLNS which I feel is a good compromise that helps the dedicated coin miners share rewards equitably with the port 7777 miners. On the faster coins the time is set very low, so the multiport miners won't continue getting paid for very long after hopping off a coin, and they also won't take too much of the dedicated miners' rewards if a block is found shortly after the multiport hops to that coin. It also ensures that on the longer coins, people who have been mining on a coin within the past X hours will get paid for their efforts and not have their shares thrown out of the round due to the multiport submitting tons of shares. I could change the multiport-only coins to a Proportional system, but that might result in some people not getting paid for some blocks, since on the really fast coins sometimes we find blocks within seconds of each other and there might not even be enough time for everyone mining to submit even 1 share. It would also add complexity to pay different coins using different systems. |

That's almost a full day's worth of what dustcoin says that I should be making if I was mining LTC directly, in about 10 hours.  Anyway, I'm taking a little break from multipool today after working on it for 20 hours straight yesterday. I'll keep an eye on the switching, but other than that I will address any other issues tonight or tomorrow. |

In the space of 20 minutes around 10 PM PST 7/10/2013 Cgminer reports total of 96 shares lost due to stratum disconnect. Any way to prevent this?
Ran into the deadlock problem again on the db.. So I am turning off vardiff on the pools that have it enabled. |

Too much switching too much coin hopping, none become efficient or profitable. LTC which has not been on mport for a long while.. Time Since Block Found 31 Hours 31 Minutes.. directly proportional to how much the "Pool" mines the coin specific. If you are constantly switching coins/pools/blocks there is no way to keep it profitable. I will be proven right watch. T. Even without the multiport, we have enough hash on LTC to find at least 2 blocks a day.. We've just been unlucky today. |

NVC is highest now
when does multiport switch?
today is not my day apparently.. Anyway, we're on NVC now. |

how can I have unconfirmed coins, but 0 round shares?
Round shares are how many shares you have inside the current round, they have nothing to do with blocks that have already been found. But to answer your question, it's because your shares have expired, but the blocks that were found while you were mining haven't yet been confirmed. NVC takes 520 confirmations to confirm a block (~3 days) and FTC takes 120 (~3.5-12 hours depending on network hashrate). The others should be confirmed fairly quickly. |

yeah and that multipool connections 0 makes not a good feeling  Oh, I need to fix that.. It's not accurate anymore with the new architecture. |

Getting TONS of orphans on WDC.. Lots of other people must be mining it...
Have a look at the pool stats for WDC. The SAME block gets submitted by the same finder multiple times (but strangely enough minutes apart). Only the first find counts and the rest get orphaned. No, that's actually a display bug that I haven't gotten around to fixing. Those orphans are actually valid transactions marked 'orphan'. |

Can one miner log into both the US end EU server at the same time?
I have set a few miners to use both the US and EU servers with "load-balance" on in cgminer.
They do submit shares to both pools but I see stratum disconnects often so I'm wondering if this is because I connect to both servers at the same time.
Hi Flound, Can you comment on my question if it's a good idea to run both the US and EU server in a load-balanced setting in cgminer. Why, are you in the middle of the Atlantic ocean? I can't really answer that, my gut says it would be better to set one as primary and the other as secondary, but I really don't know. I've never run load balanced pools in cgminer. But you should definitely at least set the US pool as a backup if you're using the EU pool, as the EU pool is currently only a single server. |

Maybe WDC needs a higher "adjustment factor" for orphans.. until they change the software for longer block time as per their recent PDF.
i could do that, but even at 40% it would still be the most profitable coin right now... My miners have been smooth sailing. Anyone seeing stratum disconnects? |

I am in, any welcoming comitee? Welcome Behemot! |

Seems to be working well now, thanks Flound!
Quick question, since the multiport basically gets us to pool hop (and there's a LOT of hopping going on over the past 24hrs), wouldn't it be best if the reward was proportional instead of PPLNS.
Maybe it would be.. I'll think about it. |

"/Rant: Unfortunately what is going on is what I feared would happen. With so many alts on the multiport now, it is switching coins so often none will be really profitable. The profitability is useless to look at IMO since by the time you get any and trade them, their value has dropped. I don't care except for the fact I joined pool to mine LTC and the multiport may never switch to LTC again with new alts popping up everyday.
If you have coins and sell them at the moment profit is high then it may count but that's counting chickens before they hatch. The PPLNS method from everything I've read says your efficiency doesn't get to max until you have been mining for at least 24 hours, so how can mining for a few minutes here and there on any coin do any good? /Rant"
GL all.

Also, the low confirmations I have set on most coins make it easy to transfer and trade them quickly. |

Torn, you can mine LTC directly on port 3334 if you want to. |

You should set a fallback pool in your miner config like most people do.
It IS mining just terribly inefficiently. That wouldn't have been possible at the time you posted since all of the poolservers and the db were down. |

Looks like the pool is back up and mining WDC. The user stats still aren't refreshing though.
We're up.. Stats will take 10-15 minutes to return to normal. |

flound is working hard on it to get it running smoothly.
i think its a big work with us and eu server now and many new coins on multiport.
we should give him time to get things running.
Yeah I think flound should let his system settle down. It seems like in the past week there are hiccups every day if not every six hours. With people demanding new coins or different systems and what not. If I were him I'd wait till the system runs fine for a month or so and handles scaling growth acceptably before powering in more features. At the EOD though it is his product to do what he wishes with. There have been a lot of hiccups in the past week. That's exactly what I plan to do once things are running smoothly. I need a break! The recent issues aren't really about the new coins though. Most of the issues are due to concurrency issues running multiple copies of stratum. It wasn't showing up with only 2 backend servers, but now that there are 6, it's causing some unforeseen issues in the db. I'm watching the db closely right now to see if the upgrade fixed the issue. |
