Wow! My miner found a block. Number 285163. A first for me.

Mine found 2 a couple days ago throughout a single day and my rig is microscopic in comparison to what I see out there. Is that equivalent lightning striking twice?

yes very odd.. a friends 60gh/s rig found 2 blocks last week. essentially an impossible feat in comparison. but luck is luck, or someone is manipulating the data

I have to ask: do you get any kind of "Bonus" when your hardware finds a Block? Or the usual reward you would get for participating?

i am the one without any idea what he is doing, also i take donations ^^

It depends on the pool. With Slush, no bonus.  Other pools have different rules - p2pool pays a 0.5% bonus to the person who finds the block.

Thanks for the Formula's and explanation. I for one will try this. Probably not until the weekend, But I will get back to you with my results.

I'll be interested to see how you go. Keep us posted?

OK so here is what I got:

Round 21628 Thru 21657 = 30 Rounds

Total Shares = 78149042396

All blocks solved at Difficulty - 2,621,404,453.06

2,621,404,453.06 * 30 = 78,642,133,591.8

So Total Shares - 78149042396/78,642,133,591.8 (Difficulty * 30) = x

x = .993729936189684

k=30, lambda=30, x=.993729936189684

RESULT = .5105800139110

OK! Now it's up to you to tell me/us what this number means  Huh

Thanks

The "RESULT" is the Erlang distribution cumulative distribution function p-value. From Wikipedia, the CDF "is the probability of observing a test statistic at least as extreme as the one observed".

In this case results refer to the lower tail probability, so given a value of 0.5105 this means that there is a probability of 0.5105 of observing actual shares/expected shares of 0.9937 or less.

In other words: If you did the same thing for one hundred other group of 30 blocks, you'd get better luck 51.05% of the time (and worse luck 49.95% of the time).

So the 30 blocks that you tested were very close to perfectly neutral luck.

Well again Organofcorti, thank you for that! It's the most tangible explanation I have seen to date regarding the pool "luck". I hope others grasp this as well and realize that things seem pretty neutral. I know it sucks to have these LONG blocks, but I do think it's right in line with the "luck"  of this pool overtime. Translation, I don't think there is any monkey business going on behind the curtain  Grin

Completely new to this so if my question is stupid I will say I am sorry now.  I have setup cgminer and configured a batch file to run it.  I was not able to get the batch file in the knowledgebase to work but I have gotten it launched with this

I:\CGMiner\cgminer.exe -o stratum+tcp://stratum.bitcoin.cz:3333 -u XXXX.worker1 -p MyPassword

However, when I turn on verbose logging I see this...

(5s):0.00 (avg): 0.000h/s |A:0 R:0 HW:0 WV:0.0/m

This makes me suspect its not actually working. So here are my questions:

Is it working and there is simply nothing to work on now?
Is it not working and there is an issue with my batch file? 
Is it not working and likely a firewall type issue?
Is there a way to tell how many MHash/s I am running?

Any help would be appreciated.  I do see other messages besides the above such as work update received and but my numbers continue to be 0

(5s) and (avg) are your average hashrates for the last 5 seconds and from the program start respectively.
(You can find this information in the CGminer README file.)
So you're running zero MHash/s. So: It's not working.
The other messages can help you in finding the reason.

91% 30-day luck.. That's pretty awful Sad

yeah, and it was all in the last week essentially that pulled the 30 day average down about 10 points. . .  So figure how bad its been the last week and there is your answer. .

Just this week - about 3 of the days this week I am about 1/3 of my normal average, so it has definitely been a very bad run of luck this week. .    and its like the hits keep on coming with long block after long block. .   

Here's hoping things normalize themselves, but it almost seems like the normalization will occur with the luck metric resetting itself vs us getting better luck to normalize those numbers. . .

Luck always looks worse if you average over days instead of blocks. The long rounds take longer, so "luck" looks worse than it should be.

No doubt.. .   I check once a day or so. . .   If I see 6 blocks looking for confirmations (about 36 hours worth of stuff), then its about average. . .  If you only see two or one (like right now), then that means there haven't been a lot of blocks done. . .   right now its one block, which means the current block was long enough for most of the earlier rounds to all be confirmed. . .

Hey all - I am unsure as to the normality of the following as I am new to mining, so a little advice would be helpful please...

It appears to me that every time a block is found and the stats page has the 'processing' message for the block that was just found, my hash rate dips 6 - 10 gh/s (not stuck at one interval, when I refresh the screen it varies between 6 & 10 Gh/s).

I noticed the dip on a block about 4 days ago and just passed it off as some sort of network re-adjustment. I bounced the miner client and it didn't help. I looked an hour or so later and everything was normal, so I figured I must have needed a reset. I noticed it again a couple of blocks later and tried the same thing, but watched it more closely. The hashes only came back up after the last block quit processing and showed my BTC reward. I then started to watch for a correlation. After closer notice of the last 7 blocks, every time a block is found I see the trail off in hashes and as soon as it is done processing the hash rate bounces right back. Is this an accepted pool trait or should I be looking at my mining hardware?


- Thanks -

My guess would be that the Mhash/s* is adjusting since it's on to a new block. That hash rate number is based on "shares so far" on the current block so the bigger rigs probably take over a little faster and then it smooths out as time goes on. Just my theory. I guess it would only be problematic in really fast solved blocks? But I don't think your equipment has any issues if it comes back over a short time.

19 more confirmations and I'm tapped out! Have not seen that since I started mining. This surely has been a funky couple of weeks!

EDIT: Well that 15:25:45 block came in before all my confirmations, so I've still yet to be Tapped!
