Can anyone explain the effect of worker difficulty?  I see where it asks the expected hashrate of the worker and then raises the difficulty for that worker if the hashrate is very high.  What effect does this actually have?  What effect does it have on a worker to have too high or too low of a difficulty set?  I googled but could not really find it explained.  If someone has a link or an explanation I would appreciate it.

I still don't understand the "Suggested difficulty" field.   Dose it have some thing to do with long polling? If my connection is bad do I set it higher or lower?

It means that you aim for a share with more worth. E.g. a share at difficulty 1 is worth 1 share, 2 is worth 2 shares.. and so on. The difficulty refers to the target set for your hashes. At difficulty 2 there are half as many possible hashes which would contribute a share when compared to difficulty 1.

The reason it's useful is that with a very high hashrate (>2GH/s) you'll find so many difficulty 1 shares that it'll use up a lot of communication and it floods the server with requests.. so if you look for more difficult shares, you still (theoretically) get the same rewards, but the communication with the pool server is lower.

Hope that helps.

Slush's real name is Marek Palatinus: http://blog.bitcoin.cz/author/slush/

There is this whole thing called vanity mining where people generate millions of bitcoin addresses just to find ones that contain a specific string Smiley

Who is Marek? was this just a chance address or did you engineer it? just curious.

Regards to recent higher invalid ratio - it was caused by the move of bitcoind to another datacenter and by poorly connected bitcoind to outer world. I made some changes and bitcoind should be well connected now.

Slush, I find the same. Something odd with 17719...

It does appear light.  I'm sure Slush will recalculate the reward...

hey slush, I know that you are busy dealing with stuff at the moment.. so i am not asking for this any time soon..

but at some point would it ever be possible to grab the graph data in json format?

thank you for your time, effort, and for making this pool very nice!

Just my luck... A 660 mhash miner was down during the good luck period... But then again it could be worst... It could be 920 mhash miner or both.

I just checked the Slush stats, and I can't stop wondering why Slush with 8Ths is making dozens of times less nmc blocks than bitminter pool with its 5.8Ths: https://bitminter.com/blocks?commodity=NMCHuh

There is no place like 127.0.0.1

I have a question that I can figure out.

Current shares CDF:   89.01 %

So If we have 100% luck would that mean that we would find a block at 50%? So about 1 hour at current hashrate? And about 24 blocks per day?

It dosen't look that way to me. Curently we have 110% luck and in last 24 hours we fond only 20 blocks and I would look at 26 if that was the case... Can someone help me figure this one out. What is a CDF % for 100% luck?

Or is there a case that there isn't one and 100% luck can mean diffident things?

Thanks

Only getwork is mining NMC. It is only 3% at the moment... If you are using stratum you still get NMC(basis on your BTC shares) but you don't mine them... But you get them only if you entered NMC wallet addres. So not everyone is getting them...

Block 17731 I got just bit bigger reword as before fail miner restart... I restarted it 20 to 30 minutes into the run so there must be something wrong....
Also Block 17719 is off by about 30%

Unless I had some network issues that I didn't noticed...

I think he explained that earlier...

Stratum pool don't have support for Namecoin (yet), so around 30% of hashpower isn't mining for Namecoin. Still you should have higher namecoin income than on other pools, because quite a lot people didn't filled NMC address...

I'm considering to drop of NMC support, because this project is basically dead and current merged mining sources are incompatible with latest bitcoin development (no support for merged mining over getblocktemplate etc). There's no project development since merged mining has been introduced in last October...

I am not quite sure, but i think 100% luck is 63% CDF or else if the pool finds a block after exactly difficulty (as number) shares:

Luck for the day = number of shares for the last 24h / number of blocks / difficulty * 100

Just for the information, I also have problem with reseting my password (no email arrived). It is no big issue though and definitely not a priority. (There is nothing valuable in my account and I do not use this password anywhere else.)

Edit: My mistake. I entered wrong email.

I do have issues in last 3 blocks. What happened? Miners are up and running and this is what I got.
