Well, it has also to do with luck i guess...in the top 50 list there is someone with several blocks on his name and only hashing with 20Mhash/s

cuz they found those blocks when 20mh/s was GODLY!

Yeah, but he could have been hashing with 20 mhash since 2010 and found blocks when it was still profitable to mine with a cpu.

Or he could have started last month with 100 ghash, but is now having network issues, and can only mine with his laptop's 7750 @ work...lol

There is a lot that list doesn't say.  

[BadAss.Sx]

Ah well, whatever...finding a block does not give us any advantages...

[gourmet]

So why the big fuzz that i have found a block in my statistics lol?

well, you can be happy that you became a part of the bitcoin history

I have still zeros by all my workers. :-(
When there is a non-zero number, will it become clickable and linking to the list of found blocks?

[gourmet]

I do not think it is very difficult. The value of each share you submit is calculated with the following formula:

score_share = exp(t/C)

where t is round duration in seconds, and C is a constant, currently 200. This means the value of each share is exponentially growing, so old share have significantly lower value compared to recent shares. So if you stop mining while others don't, your part of total pool score for that round will decrease exponentially. You can read the original post about this reward calculation method here: https://bitcointalk.org/index.php?topic=1976.msg50002#msg50002.

Additionally, based on measurement I have found that each hour, t is reset to zero and your score is divided by exp(3600/C). This is probably to prevent an arithmetic overflow (see http://en.wikipedia.org/wiki/Arithmetic_overflow).

Hope this helps,
   T

(emphasis by me)

(Also the whole pool's score is reduced by the same factor, not only yours.)  :-)
[edit] (In fact, it's the pool's score that is the candidate for arithmetic overflow, not the your one...) [/edit]

Thank you very much for posting the constants that resulted from your research, Tibor!

I've noticed that the current round (19720) score had been "reset" at about 20 minutes round duration for the first time and then between 1h 21m and 1h 22m for the second time.

I've looked just at this round, haven't examined any other one.

[edit] Next round (19721) first reset at about 1 hour 14 minutes. [/edit]

if I have 16 asics pointing to 1 WORKER should I raise the diff?!
All on one machine.

I have found 1 block, it was the second day after starting up my first 10 USB miners. The block number that shows under my workers is a hyperlink to the block.


Found blocks
239418

Anyone else has the problem they receive alot less then normal now per block? Normally i receive around 600000 but all of a sudden it hangs on 29000 per block...

edit: fixed

Almost made a post worried about payout..
Then noticed 40450.699 Ghash/s for the pool - wow

hi Slush,

can the namecoin to be add back to merge mining?

That would be nice yes

Hmmm, looks like it's almost time to take a break while waiting for the BFL 60 -- or at least get a Raspberry hooked up.  Profitability after energy cost on my FPGAs is down to a couple bucks a day.

What is the reason for invalid rounds?

[threedrules]

dont know, but the last one isnt invalid

[BadAss.Sx]

I do hope it get fixed...it's a little bit annoying lately

[mdopro1]

Today I had a hour and half long round end up invalid so it's not such a huge deal but I have also seen a 4 hour long round going invalid. That's a good chunk of the day gone bad.

I'm not complaining, I just want to know what happens and why a round ends up invalid and what is the justification of it?

[BadAss.Sx]

We all don't know...most of the time it gets valid eventually, so let's wait, but sometimes you are hours busy with mining and it ends up invalid...that's not nice

[cr1776]

I switched about 90% of my miners to a different pool today while all this gets straightened out.  I've mind for 2.5 years with slush, and kept about 10% still here now to see how it behaves, but have been bothered with the shares being marked invalid, then back to valid later (in the good cases).

I'm sure it is nothing, but just didn't want to take the chance.

[mdopro1]

I see. I never check back to see if invalids turn valid again but I'll check this time. Thanks for sharing the info.
