How do donations work? Does it allocate a percentage of hashing power to the owners pool or something?
That is my understand. For example if you donated 0.5% 99.5% of the time the miner will work on your pool 0.5% of the time it works on the developer's pool. Correct. I went out of my way to make it as unobtrusive as possible. Therefore if it can't connect to my account it will just quietly stop getting work from there. It will not roll work, and it will only get *up to* the donation amount of work to do. Therefore if you set it to 1% it almost never will actually amount to 1%. Submitted donation shares will show on the screen as "donate" instead of "pool x". You can tell how many shares are submitted at the end in the summary (unless you are on windows and have the binary which crashes on every exit and get no summary). |

i supose one option is to have a timer on the (press enter to exit) and then it just retries.
Now that makes sense! |

have a small problem. had a power failure last night and when the miners restarted i got the following message [2011-09-29 11:48:07] No servers were found that could be used to get work from.
[2011-09-29 11:48:07] Please check the details from the list below of the servers you have input
[2011-09-29 11:48:07] Most likely you have input the wrong URL, forgotten to add a port, or have not set up workers
[2011-09-29 11:48:07] Pool: 0 URL: http://btcguild.com:8332 User: ****** Password: ******
Press enter to exit:
I expect it was just a network hiccup, is there anyway i can easily prevent this from happening... with winter storms around the corner i expect a few power failures occurring and would like the miners to start up smoothly note: running on Windows7 64 bit Presumably this is because your network is not connected by the time your mining has started. If you are scripting some kind of auto-startup, you need to make sure the mining happens late enough that the network is up. Perhaps a simple wait or sleep in your windows .bat file would be enough (not sure of the syntax in windows) so that it waits for a minute before starting. The error is there for a reason as 99% of the failures people were reporting were they had entered the wrong details. I guess I can add an override as (yet) another command line. |

Enable 0.5% donation by default. I plan on maintaining a patch to remove all of the donation code from the project starting in the near future. I think people who want to donate (such as myself) are capable of choosing to on their own through the normal channels. You are free to do as you please. The donation 0.5% by default patch was testing the waters and proved within a heart's beat how popular the idea would be. There is no default donation in the code, but I am not removing the --donation option. Thanks very much to the handful of people who are actually using the donation feature by the way! Even a tiny bit is appreciated  |

Does having x workers for x GPU gain you anything?
The pool's idle worker notification actually becomes useful? How would one decide when to separate them out and not? Most of us don't want it to do this and you'd have to have some convoluted command to link one account to one device and only when you want this. The command parsing is messy enough as it is  |

You have been bitten by the windows-is-failing-to-build-you-a-kernel bug that I have no idea how to fix short of installing linux. Restart it over and over and eventually it might work.

No. Run separate instances if you want that.

Hi! Could you please help me. I am looking forward to run cgminer but I can properly configure it.
Please post the right settings for me.
THANX
I need my rig to switch to the 2nd pool if the 1st is down. I have 4 GPUs. The 3rd one ( device 2) is used for descktop. The also have different mem and core clocks.
Is it possible to configure cgminer to satisfy all these demands?
Yes it is. I can't guess what settings you want for mem and core clocks, but assuming mc0 is the memory clock for GPU 0 and ec0 is the engine clock for GPU 0, something like this: cgminer -o url1:port -u user1 -p pass1 -o url2:port -u user2 -p pass2 -I 9,9,d,9 --gpu-memclock mc0,mc1,mc2,mc3 --gpu-engine ec0,ec1,ec2,ec3 --auto-fan |

55BTC/block at ozco.in next 10 rounds - come earn 10% more This is awesome. |

Would love to see the Changelog in the first post. Otherwise I have to search the forum for each changelog..
Or you could read the NEWS packaged with every release...  |

You can currently pause one device at a time from the Gpu settings menu. If you pause it and the work goes stale, it's no big deal as cgminer just throws out stale work and grabs fresh work. Cgminer goes to extreme lengths to avoid working on, or submitting, stale work.

I just installed 2.0.5 from git, running smoothly as always.
I guess that I will start the features-for-donations requests:
1) The ability to pause/unpause mining. Ideally this would be easily done by another program (without sending keystrokes). I am thinking perhaps a SIGINT or SIGCONT could stop and start mining respectively.
I recently switched to hourly based electricity pricing and plan on evaluating the feasibility of mining every hour. That is what inspires this request to be able to pause mining during peak electricity demand.
Thoughts?
There already is a time based scheduling option. I suspect that suits your purpose? --sched-start <arg> Set a time of day in HH:MM to start mining (a once off without a stop time) --sched-stop <arg> Set a time of day in HH:MM to stop mining (will quit without a start time) |

New version: 2.0.5 Links in top post. The linux binary archive also includes a cpuonly binary. - Intensity can now be set to dynamic or static values per-device. - New donation feature --donation sends a proportion of shares to author's account of choice, but is disabled by default! - The hash being displayed and block detection has been fixed. - Devices not being mined on will not attempt to be ADL managed. - Intensity is now displayed per GPU device. - Make longpoll attempt to restart as often as opt_retries specifies. - We weren't rolling work as often as we could. - Correct some memory management issues. - Build fixes. - Don't mess with GPUs if we don't have them. |

Thank you for the bug reports  |

Thanks. For some reason some printfs seem to interpret %% as some kind of control character instead of showing percent  . That was meant to be a fan percentage. I'll investigate further ... sigh. The random different interpretations of apparently portable code never ceases to amaze me with its level of fail. |

Thanks guys! Nothing like threatening to make donation part of the code to bring out the donations! I haven't seen this many donations in a while I really like the "vote with a donation" idea, that's awesome However pretty much every feature that I'm interested in implementing has been done  Anyway adding the donation "feature" isn't that hard, and some people have expressed that they would use it, so I will include it next version, but after much consideration I've decided that it will default to 0.0EDIT: The --donation feature is now in the git tree. |

That's not a bad idea as a way of notifying people, but it could easily appear to be nagware. I'm thinking that anything I do no matter what will be criticised so fuck it, I'll just make it opt-in by setting the default to 0. Likely I'll earn maybe 1BTC from doing this in the next decade, but at least I'll give people the option. It wasn't even my idea in the first place so those who suggested it hopefully will use it  As for its effect on your statistics, the locally visible accepted/reject rate will include any donated shares, but it will have absolutely no effect on your statistics with your own server since it will be separate. My plan was to query my own server for login credentials and then use those, in case conditions change in the future, but for now I was planning on using ozcoin. The only issue is it will only work on bitcoin, since the block chain has to match. ...On the other hand I could just forget it. These are the issues I didn't want to have to tackle and it's starting to piss me off dealing with them  At least if I don't get any donations I don't feel obliged to do stuff. The time I dedicated to developing this miner was extreme, and I no longer have that much spare time to dedicate. |

I would not make donation mandatory. The intent would be for --donate 0 to be no donation. Human nature tends to accept defaults, and if I set zero by default, I'd say no one will donate. On the other hand, I don't like forcing people to donate by making the default on. So I'm torn on this issue too.

I've considered your request and believe that the responsibility should, unfortunately, rely with the proxy software. cgminer is simply given a url and works with that. Resolving the IP address per work item has the potential to actually be quite slow. As far as I'm aware, some big pools use a round robin system of their own without problems.
