[1500 TH] p2pool: Decentralized, DoS-resistant, Hop-Proof pool

seems the p2pool HASHRATE stop growing ?
what's wrong? full?

Variance. 
As hashrate goes up block variance goes down. 
As hashrate goes up share variance goes up.

This is a non-issue for large miners but for small miners large share variance can be discouraging. Waiting 2 hours for a share only to have it end up orphaned and payout = 0.0 can be rough.  I think in the medium term p2pool can grow by encouraging small pools to use p2pool as a backbone to reduce variance. 

Longer term something needs to be done to help smaller miners w/ share variance.  There are a couple of potential solutions.   Personally (unless forrestv can school my on any misconceptions) I think p2pool evolving to be a high difficulty backbone with longer timespan between shares supporting large miners, "subp2pools" and conventional pools is the most ambitious but also most comprehensive solution.  It could scale to support a significant fraction of Bitcoin total hashing power.

Anybody running an old version is going to have p2pool stop working. That's going to affect the hashrate until everyone upgrades.

Yeah c'mon you slackers!  Hurry up and upgrade you're slowin' me down!

I have read the wiki but still do not understand how I get namecoins as well as bitcoins with this pool. What do I do to get namecoins?

mine them solo.  p2pool is bitcoin only however you can solo mine NMC at the same time via merged mining.  There is no sharing of hashpower, blocks, or rewards for NMC though.

Solved 2 namecoin blocks! Woo.  Been mining since last June and this is the first solves I've gotten lol.

Having a Litecoin mining problem.  Usually when a mined block comes in, I get little over 1LTC but a few times a day, the transaction randomly comes in at .3 or .2, something like that.  About 50% of the time, I see that all my shares in P2Pool go instantly from normal to orphaned  eg:  125 (8 orphan, 1 dead)  to  125 (124 orphan, 1 dead) which drops my payout down to a fraction of what it should be.  If I reset P2Pool, my shares go back to normal and resume normal payouts.

Now in this case, my shares didn't go orphan but I still got the random low payout. Also, as you can see in P2Pool my payout should have been 1.2LTC for that block.  P2Pool is the most recent version JUST released but I was having the problem with previous versions and I do not have this problem with Bitcoin P2Pool.

Thoughts? Suggestions? Criticisms?

Setup namecoind with "server=1" in the conf and add "--merged <namecoin info>" to your run_p2pool.py command.  What more do you need to know?

I'm having problems with LTC p2pool mining too now after updating to latest version,for some reason when i start minerd my hashrate in cgminer plummets by about 50%.

So I'd also appreciate some help!

There was a fix for behavior this in the most recent release, 0.9. Litecoin's blocks are 4x as fast as Bitcoins, but P2Pool cached the last 1000 shares regardless of which blockchain you were mining on, and chose the wrong chain if the block headers from 24 hours ago weren't known. However, if you still have problems, please do tell me.

This doesn't sound like it could be P2Pool's fault... Try Litecoin mining with less threads so cgminer has some cpu headroom?

Yes, my post is from after 0.9, I installed it last night right after the email went out.  It has happened twice today, once when I saw all my shares go orphan and other time they didn't.  How does something like this happen?  Not that I claim to know much about how this all works but, to me, it doesn't seem like it should be possible that P2Pool gets confused, I get 10% of what my payout should be then I restart and it goes back to normal.. Where did the extra coins go? 

I honestly don't care all that much since it's Litecoin, which are borderline worthless and getting worse by the day.  I guess it just makes me worry fundamentally about P2Pool if my work can disappear this quickly.  Could work be faked just as easily?

Ah, sorry. I thought you meant in your first post that you hadn't seen the problem with 0.9 yet. Looking into it now.

Strange.. never seen that before. Check the date on your computer, maybe. If it's about a day behind, Bitcoin's Feb 20 protocol change could be causing this.

I'm having a terrible time getting p2pool to report my hashrate.
I have everything installed correctly, proper ports forwarded, and cgminer reports that it is working.

Here is a screen: http://dl.dropbox.com/u/9542654/ugh.png


Any ideas?

Thanks,
Garrett

Bitcoind not up to date? What's the output from "bitcoind getinfo"?

[ancow]

Is cgminer reporting any submitted shares? I'd assume not, which would be why p2pool doesn't think you're mining...

No it isn't. What does this indicate?

This:

    "balance" : 44520.93652163,
    "blocks" : 197724,

That is without p2pool and cgminer running.

Depending on your hashrate either that you need to wait longer or that there is some problem with hashing stopping you from producing shares.

Are there any lines like the following in your p2pool output?

Code:

2012-02-21 01:14:13.976993 New work for worker! Difficulty: 0.999985 Share difficulty: 584.493139 Total block value: 50.045000 BTC including 104 transactions

If not then cgminer isn't requesting work from this p2pool instance.

Nope. I have about 700mh/s on this rig so if it was working it probably wouldn't take terribly long to submit a share. cgminer does notify me when a new block is being worked on, but that's all.

When I try to connect to bitcoind via http I get this: {"result":null,"error":{"code":-32700,"message":"Parse error"},"id":null}
