Guys,
Technical question: How does CGminer split its job in an ASIC miner?
Background (I tried to go in depth in the C code but I still can't find the right function for it):
- I am trying to hack together a ASIC miners' hashing boards to work together in a particular way
- Assuming that it's for Bitcoin mining and given an ASIC miner like an Antminer S9 etc and assuming I have the drivers for it
- I know that Stratum will issue the extranonce2_size and other header details to CGminer
- How does CGminer split the job between the different boards/chips? I assume it splits the job based on the returned extranonce2 values generated as it doesn't look like a simple increment of the extranonce2 from 0x00 up.
Any ideas or fingers pointing in the right direction will be super appreciated.

It is not. It was made from when kanopool was called kano ckpool and everyone referred to the pool as ckpool. |

I've updated the rental port 4334 to have a minimum diff of 1 million.
 Giving it a spin with ~2PH for 24 hrs.  |

While no one was renting, I updated the rental port 4334 to have a minimum diff of 1 million.

Thanks mate. How is the payout calculated once the block is found? Based on how many shares my.miners generated?
When you say long enough what sort of timeframe you referring to?
At the moment the website says only 4 blocks found ever? Is that right?
Yes, shares. Months, unless we get bigger. Yes only 4 blocks. |

Hello all
Noobie here. Been looking ast ckpool for a while. I have 2 x s9s going on multipool at the moment.
Would it be any more worth pointing at ckpool?
I plan to get a few more s9s in the coming weeks.
Just struggling to understand how ckpool pool works.
Pls pplns etc btc boohahah is confusing. Lol.
Cheers in advance.
Here's the lowdown: You hash for us, if and when we find a block you get a payout. Blocks happen every few weeks on average. Do it long enough and you earn more than elsewhere. |

Man, I have to say, I love you. Thank you for increasing our knowledge.
Indeed, thanks ComputerGenie, you are fast becoming the patron saint of the pool. Thanks from me too  |

1. yes 2.yes nothing's changed at the solo pool for many months so something's changed at your end |

hi
im trying to use --suggest-diff but when i add it at end of my command i get rejected otherwise it work with difficult of 4k i do something wrong or ck does not accept --suggest-diff anymore
thanks for help
First thing: You don't need it. It will get adjusted eventually, I think up to 15 minutes. Let your miner just mine and diff will change to lower value. Besides, you don't need to see any shares really to mine here. Lower diff shares are just for you to see nice statistics, but they will earn you nothing, this is a solo pool. But to answer your question: suggest-diff works just fine for me. I have Antminer U3 60GH/s and I set my suggest-diff to 64. I did that by setting this in config file: thanks for quick reply i know solo thing but i want to use --suggest-diff and it dose not work and its on my nerve why it isnt and your way didnt work too it still start at default 4k  helppppp 1. Are you actually using the latest cgminer? Only cgminer supports it. 2. Are you specifying a number with suggest-diff? It doesn't work by itself. e.g. --suggest-diff 64 |

I am saying this because I have 675 TH in antminers S9 (for me its a lot of money), I did a test with 4x at ckpool and I still did not received a penny for it. I know that some point I am going to receive, but at BTC.com pool I am receiving 0.0964532 per day....
I think CK pool can be more profitable, but I am still without knowing how.
I need to make something absolutely clear to you and other newbies, as I don't like people coming in without really understanding and then complaining bitterly if things don't go their way. In the long term, the ONLY thing that matters on a pool is the efficiency of the pool and the fee - on ckpool the fee is absolutely zero, and the ckpool software and setup is the fastest most scalable software so the most efficient. HOWEVER, and you must understand this completely - a small pool like this can have good and bad luck. There is absolutely nothing I or anyone else can do to force luck in one direction or another, nor is there any way to predict luck. Luck will have more effect on your profits than anything else in actual fact - the smaller the pool, the more important luck is to profits. If you are on a PPS pool, you will earn less on average than a PPLNS or SPLNS pool, BUT you can be guaranteed you will get exactly a fixed amount at fixed intervals. With a small pool, if the pool is lucky, you can earn far far more than a PPS pool, BUT you can also earn far far less if it is unlucky. How lucky is lucky? It's possible to find a block in 10% diff meaning your profit on that block can be 10x higher than normal, but it is also possible to find a block in 1000% diff meaning your profit can be 1/10th normal for that block. On average, it averages to 100% diff - that's exactly what diff means. However there is one more variable to understand - if bitcoin diff is rising, and there is every expectation that it will continue to rise, if you score a lucky block here or on another small pool, you will be ahead profit wise in ways that you can never make up on another pool, BUT the converse is also true - if you score an unlucky block, you can never make up the lower profits. Ideally a pool should be large enough to smooth out that risk such that only fee matters, but it's extraordinarily hard to get sheep to leave their antpool and friends and make small pools large enough. How big is big enough then? Ideally about 10x larger than this pool currently is... Good luck and keep on mining. |

disregarding capacity issues, can 2 instances of ckpool (of course, one splns one "solo") run off a single bitcoind?
Sure, provided you name them differently so there's no conflict over sockets. |

Port 4334 difficulty is set to 1 million, just how freaking high does your rental service want it? ....
Is that true for this pool too? For whatever reason they keep showing 2 levels, one at 1M and one at 500K, and they're disconnecting when they show 500k (even when it's under 100TH).  Sometimes I swear that certain things (especially nh) exist solely because there isn't another viable alternative.
Yes, 1 million is the starting diff and 500k is the minimum diff. If the shithash service connects for a while and doesn't send anything it probably drops to the minimum. |

Welcome to our new miners and thanks to CG and others renting. We pushed above 10PH for a little bit there. Keep on mining |

Hi,
I want to rent some hash to find my luck! I tried port 4334, but always receive this error: "Pool difficulty too low"
I know difficulty doesn't matter in this case but is there any idea how much diff i should set for diff to not get this error?
Port 4334 difficulty is set to 1 million, just how freaking high does your rental service want it? You have no control over diff as the user. |

Its NotAllGoingToPlan  Apart from finding blocks, what's the plan? |

Can someone please fully explain the payment model for me. After 3 weeks I really feel I am wasting my time extremely. I understand payments do not occur until blocks are found. As I read it, only 150 miners are paid out and only 50 of those are smaller miners “me”. As I understand it, Since 08/23/17 only 450 miners have been paid, and of those, only 150 make up qualifying smaller miners. Is that correct? Or if this answer gets to the same point and is easier Do I have any prayer of getting paid within the next 2 blocks found? "15kmPJN9rAJFH4pGyYM7T3QSHh3y1fk5zX": 43252347.0355,
What's your hashrate and work out what your chance of getting paid at any other pool is. |

Hey guys.. ok so i only have 4 days experience in mining..
i have 1 Antminer S9.. and my electricity cost is negligible.. would i have a chance of mining a block solo on ckpool? is it worth the shot?
im willing to keep my antminer pointed there for 4months..
You have about a 1 in 1500 chance of finding a block each day. Go elsewhere for advice on shitcoins please. Ok so i do have a chance.. can you tell me how you calculated that? It's actually a bit lower sorry, I did a rough estimate and diff has risen from when I last checked. It's in in 7700 per day. 4.2gigahashes solves 1 diff 1 share per second. Current difficulty is 2,227,847,638,503, which means you solve a block on average every 2.2 trillion diff 1 shares. You have 14 terrahash or 14000 gigahashes so you solve 288 million diff 1 shares per day. |

Is there any way to make p2pool mode modern so it can use multithreading and multi cores etc?
Rewrite it from scratch in another programming language. |
