Hey slush..

Would you look at my shares on block 230199 - they are not correct.  Way under count.

Thanks!

I'v been pool hopping for a few weeks now. Looking for the best payouts. And this is going to be a dumb question but where it says "Suggested difficulty" What should I put there?

ok so i put 7,673,000 in the suggested difficulty field?

Yeah, sounds good.

jk, actually, you should set difficulty according to your connection, then hash rate. 1,2,3,...8....20... ect. Not 7 million.


Of course, if you're pool hopping.... then maybe 10 million would be a good difficulty.

Anyone else having problems connecting to the pool?

I'm using the mining proxy and diablo miner.

seeing this in the console
2013-04-08 11:16:03,666 INFO stats stats.print_stats # 1 peers connected, state changed 1 times
2013-04-08 11:16:50,778 ERROR proxy client_service.on_timeout # Connection to upstream pool timed out

2013-04-08 11:16:53,591 INFO stats stats.print_stats # 1 peers connected, state changed 1 times

never mind seems to have resolved itself.

Quantus, I strongly suggest that you follow the recommendation from Crystallas.

Gramted, I'm new to this. But according to Slush's site, the payout formula is (25 BTC + block fees - 2% fee) * (shares found by user's workers) / (total shares in current round).

Can someone please check the math on this block to see if it holds true to the formula?

Total Shares: 18833717   
My Shares: 1442   
My Reward: 0.00036229
Block# 230220   
Block Value: 25.58996000

By my math the reward should be closer to 0.0019

Thanks!

Two lines under that is this: This in fact is a simplified version here is the more complicated version

https://bitcointalk.org/index.php?topic=1976.msg50002#msg50002


In a nutshell, the shares are weighted, to prevent pool hopping.

[dmphotog]

tiktoc, thanks for the info.  Based on that page things should balance in the long run.  However it still seems like it is well outside of tolerance based on the graphs on the link you provided.  Either way, I will keep at it.

On a side note, how come Namecoin rewards are no longer being awarded on a regular basis.  I am lucky if I get namecoins 1 out of every 10 blocks

"according to your connection" I have 4 GPU's on a wifi connection. What should I set it to? 4? (I am not A pool hopper) Just mean I been looking for a good pool.

The problem for me is: There was a block which took a long time to resolve, and my mining rig just self-restarted during the process due to my ISP problem, and the reward for that block became 1/7 of normal reward, this has never happened with other pools 

[Quantus]

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?

Have had a low reward on a long block from the same issue, 5 minutes downtime = half (or less) the reward I should've got.. always seems to be the case on a 3+ hour round as well :E.

The payment system treats you the same whether you were trying to pool hop or you just happened to disconnect at a bad time. In the long term it averages out because everytime it happens to someone who isn't you, you technically benefit from their lower reward in that instance.

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.

So if I needed some planned downtime and I didn't want to mess up my shares, how would I best choose when to shut down the miner?

[Quantus]

Hold the fuck up a minute! If my miners go down for 5 minutes I lose 50% of the work they have done for that block?

I got these things on Wifi Every time a big truck drives by they go out for 20 to 30 sec. What measurement of time triggers the "oh shit he's a pool hopper fuck him over" device?

Right at the start of a round, i.e. when a block has just been found.

On a longer round, yes - the score is based on an exponential function with the round time as the exponent. It's scaled by a factor "1/C", but on longer rounds this will dominate - check your score under my account. More info found in the link given above ( https://bitcointalk.org/index.php?topic=1976.msg50002#msg50002 for your convenience). The longer the round, the more important staying connected (and submitting a share close to the point a block is found) becomes.

Ah, Thought It Would Be something like that. I was more wondering how to tell but I guess it is on the website somewhere

[Quantus]

I find this system very convoluted. Clever but convoluted. Do other pools use systems like this?
The network has gained 50 PetaFLOPS in the last few weeks so I'm having a hard time telling what pool works best for me.

The network does intops not flops.

Two easy options come to mind:

1. keep an eye on blockchain.info and take your miners down when you see Slush get a block.. it updates automatically and there should be a fairly short lag.

2. Keep refreshing the stastistics page until you see "Current round duration" reset.

Since 1 is less likely to cause issues for the pool.. I'd go with that

Since most pools use systems which discourage hopping your best bet is to leave your miners on a single pool (or point each of your individual gpus/whatever at a selection of pools) and leave them alone. If you're that bothered by the variance you should pick a PPS (pays the same per share everytime) pool.. although in most cases you'll pay a higher fee to the pool for the privilege.

Questions within questions... I'll work it out though

I don't think PPS actually makes much sense for a pool. HHTT is just switching away from it as the pool funds rand down to 0 and people weren't getting paid.

It is strange that I configured my avalons to mine on slush's pool yesterday for 2 hours but did not get any amount of btc.
