I would just like to chime in about how cgminer sends misc shares to backup pools when not busy enough..


my 4th backup pool is solo (as i think all miners should have solo as final backup to protect network)

well cgminer found me this block https://blockchain.info/block-height/188729 a couple of hours ago.. what are the odds?


thank you clovias

My 5th backup is solo as well.  Though I haven't had any nice surprises like you just did.  Good for you.

I wonder how often this happens?  Anyone else find a block with a solo backup, I wonder?

Meni Rosenfeld I have seen around, answering questions and breaking down problems using complex math equations. Plenty more information would be needed, but if its possible to get an answer that is anywhere close, he's your guy. Recently I haven't come across his post as frequently as in the past, so I can't say he has the time or would even be willing to bother so...

The odds are very easy to work out.
The chance of a single 1 difficulty share finding a block is 1 chance in D
Where D is the current difficulty.
(i.e. at the moment it is 1751454.5353407)
Of course you may have sent more 1 difficulty shares, but it won't count them, only the ones that are blocks.
So in reality the chances are even better.

Those are the odds of him finding a block. The odds of him finding a block where that magic share just happens to land on his 4th pool (solo) is quite a bit lower.

hi!

i get a lot of duplicates on my ztex single and ztex quad.
almost 3.6% rejects and almost all from the duplicates.
it seems that the duplicate is send to the pool and then directly after that a new share.
anyone else got this with ztex boards? could it be a problem with the ztex bitstream that is included in cgminer or could it be
a problem in the ztex code in cgminer?

regards
streetuff

Interesting. So this happens with eclipse as well. I don't have a solution but I have an interest Wink

The p2pool problem with this is taken care of, and perhaps I shouldn't keep beating a dead horse but I would like to take this oportunity to ask about how cgminer handles roll-ntime.

  • Under what circumstances does the miner call getwork? It seems to me that it happens more frequently than expected. If long polling is supported and "expire" is set to 120 it should be quiet and just keep rolling until 120 seconds has passed, should it not?
  • Second, if it sends a getwork request before there is new work to send, what is the pool to do? It can only roll ntime, but how can it tell by how much?

Dunno what you're doing to suffer that. Probably too high intensity and/or worksize or something else...

Perhaps overclocking, but I mine the year at this frequency using the Phoenix and there are no problems. I want to use CGMINER but I have this problem since version 2.4.0

Correct; I get the same when the AMD driver crashes and recovers. Quitting Cgminer and restarting it will allow you to start mining again.

Back off on your overclock a bit. Cgminer pushes your cards a bit harder than some other miner programs, and you can usually achieve the same or better hash rate with a lower overclock.

Not in my case. Overclock down — less Hashrate.

It would be great if author would make autorestart programm, after driver crash in next version of Cgminer.

Well of course a lower overclock will get you lower hashrates. What he's saying is that CGMiner at a 920MHz OC might be equal to another program at a 940MHz OC.

Sometimes,also, with a lower overclock setting and lower hashrate you will get a higher Utility.
