Nice!  What type of setup do you have?   And why'd you leave whatever you were in before?  Just curious..

1250 Spartan6 FPGA, I was on P2Pool since January, I had to leave it (sadly) because of Pyramining's members pressure (at that time there was a very low BTC generation compared to expectations). Since I like p2pool concept, I decided to give it another chance. Let's see if it's working better now! :-)

Someone, or a bunch of someones, threw on a bunch of hash power.  We're at the highest we've been in ages.. 443g/h atm.

Now if we can just get by this 30 hour block.  I'm curious if the extra power will help or if we still have scaling issues.

M

That someone it's me, with 120GH/s, and I have 120GH/s more to add, if everythings works well.

Are you setting a higher share difficulty for your workers? You could probably get away with 20,000-25,000 difficulty shares no problem.

M

Because of the new power, my share of pie is now about .55 btc per block.  It was about .9.  So I need to get 5 blocks a day to match the 3 I was averaging before to stay at the same output.  Obviously, we've had 3 blocks in a little over 2 days.  I hope this is the returning "bad run" that we get in-between "good runs" and not a sign of scaling issues. :/

I'm not sure how it could. I don't think you can look up shares based on an address.

You should increase difficulty with the square root of the increase in hashrate.

At 20000 difficulty, a 120 Ghps miner would see a daily standard deviation in daily reward of 10% of the mean, and the 95% confidence interval would be about +/- 18%.

At 1300 difficulty, the standard deviation in daily pay is 3% of the mean and the 95% CI is about +/- 5% of mean.

Just something to keep in mind as you add hashrate to your own setups - don't select a linear change in difficulty when you add hashrate to your set up.

Question to p2Pool miners - how many shares per day or per 10 seconds seems to be best? If you submit to large a number, how much does DOA and stale increase by?

Well ... since you actually generate the coinbase transaction yourself (the whole p2 part of p2pool)
Your p2pool must know which shares belong to which address ...
But since I'm only saying that based on what must be the case, I'll go check the 'docs' now ...

https://en.bitcoin.it/wiki/P2Pool_code_documentation
share_data_type
pubkey_hash    Int(160)    pubkey hash of Bitcoin address that this share's payouts will go to

Of course I have no idea how difficult it would be to collate and follow the information to actually work it out, but the rest of the information must be there somewhere Smiley
(the 'must' is based on that fact that you can't cheat the difficulty, so it must be part of the share that is hashed)

I can't increase difficulty in phoenix.  If someone wants to point somewhere in the code that I can change to make my shares more difficult, I would do so

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).

or mine!  5.9.24.81:9332, to make me some altcoins.... my coinbase is higher 98% of the time also, due to having bitcoind with close to 1000 connections!1

actually, i dont even know if it works properly for other ppl, it might just always credit my address with any shares.  does using the -a flag do that?

As long as the people connecting to your node use their address as their username, the coins get paid to that address.

It is any sense to set it so high? IMO it should be just under pool diff shares ~500 tops.

The purpose is to take up less of the actual share slots, so smaller miners can still get into the chain.

Payouts are determined by how many shares you have, and their difficulty, so if you're submitting fewer shares, but at a higher difficulty, it will balance out and you'll still get your appropriate payout, while smaller miners don't get shut out of the chain altogether from the large miner, taking up so many slots at lower difficulty, to make up his same payout.

You can't set the difficulty lower than the normal pool difficulty and it wouldn't make sense if he did.
