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

[DopeLabs]

Yep, my node is down at the moment due to a popped PSU.  It'll be back up in the next few days, and I'll have a couple of Blades connecting to it - along with what I'm already running, that should be ~30GH/s coming back to p2pool.

How are you running your blades on p2pool?  I was using bfgminer as a getwork proxy and over 30% of the shares where rejected.  What share reject rates are you getting?

you dont need to use proxy with blades and p2pool.. just point the blade directly at p2pool as you would any other miner... note that you will get about ~3GH stale/doa with the old blades running at 12-13GH, so your only getting a real 10GH.. not sure how the new blades run... also dont forget to append a '+1' to the end of your username on the blades when connecting to p2pool.. since they only know diff1, this will stop the annoying submit > target messages in the p2pool console output...

Stales on p2pool aren't wasted work, this is explained in numerous places (and in details in the guide in my signature). So you don't get "only 10 GH".

They may not be efficient on p2pool and not provide the full 13GH benefit to the miner, but you'll have to test and report what p2pool's efficiency is over at least 100 or better 1000 submitted shares to verify that.

Does anyone have a p2pool that has all the merge-mined coins?
Namecoin, Devcoin, IOcoin? (I forget the rest)

http://fuzzypool.mine.bz/ come join... 60GH is waiting in the back of a delivery van on its way to me now and 7GH on pool at the moment... all Merge Mined coins on the pool and 0% BTC fee

few minor bugs working out so sorry for the visual errors etc but mining works and need to test more on alt coins so your hashrate is appreciated

Glad to see someone has resurrected my code.  Good luck.

I have a day one KNC Jupiter pre-order and another one due before October 15th. Will they work on P2Pool node based pools OK.  I also have three 60(GH/s) BFL SC's I could put on a P2Pool node based pool possibly but thinking of selling them soon.

It's my understanding that the miner software authors have heard _nothing_ from KNC lately, though they were told they'd be given access for testing. So if it'll work in any particular situation is a crapshoot. Historically mining code from hardware vendors has been pretty crappy.

It takes a bit of time to install p2pool and bitcoind, so if you're planning on p2pool mining them I suggest getting it setup and running early.  You can happily look at the p2pool graphs even if you're not mining on it.  Your BFLs will run great on p2pool, or you could just use p2pool as a backup for them.

try for the p2pool, how is the speed.

Yup, I do.....

Edit: But I took i0coin off - too memory sucking & drive bashing.....BTC, IXC, DVC, GRC & NMC only for now.

I0C has been updated and it's working fine. Give it a try
Can you tell me what is GRC? Couldn't find any links about it.

Sorry, it's GRP not GRC - which is GRouPcoin:

You'll need RAM, it's a bit of a hog like I0coin was before it was updated. Took me a while to compile it too, still needs some work & there's no windoze version yet or GUI. But, as they say, every little helps. I mean, if you're gonna mergemine you might as well mine them all right?

Any idea if p2pool is going to be fixed to work with ASICMiner Blades?  I just tried my Blades on p2pool, and I get a shitload of rejects.  Between 30-50%.

How are you running your blades on p2pool?  I was using bfgminer as a getwork proxy and over 30% of the shares where rejected.  What share reject rates are you getting?

Eventually got round to trying the Blades on p2pool - I'm seeing the same thing.  Abandoned the idea for the meantime until something is done about it.

[gmaxwell]

You need to set your pesudoshare difficulty to 1 with +1 on the username. This is documented upthread.  ASICminer blades are flawed and works only on difficulty 1 work even when directed otherwise.

[HellDiverUK]

Just to note that I am connecting my Blades to p2pool via BFGMiner's http stratum proxy.  I don't know how I can set the diff to 1 by device - I'd have to keep it diff1 for everything that's connecting through BFG.

Why not set up a separate proxy for the Blades and put a +1 on the username?

I havent kept up with P2pool for so long. Way back when i tried it with GPUs more than a year ago, its very resource hungry and variances were so high.

How is it now with all the ASICs?

What is the current status of the project? are there any forks from this project?

[zvs]

the ks-2g could run one adequately, but that, the ks-4g and the ks-16g are sold out

You're dreaming if you think a single core Atom will run p2pool with any efficiency.  A Celeron 847, which is WAY faster than an Atom really struggles, even running a text-only Ubuntu server install on SSD. 

The slowest machine I've had it running properly on is a Pentium G620 (dual core 2.6GHz Sandy Bridge).

Currently my p2pool node runs on my mining/workstation machine, which is an i3-3220T with 8GB RAM and SSD drive.

why wouldnt it?

it has 2GB RAM and a 500GB HDD

obviously you wouldnt want to make it public and have a ton of people connecting to it

i guess the only thing ive noticed is that with an i7-4930k you can get the getblocktemplate latency down to 0.7ms or so (though i guess this would be more reliant on having quality memory, eh).    if you chop out all transactions it'll go for 0.85 or 0.9ms on one of those old hetzner 2700k's

Still resource hungry, still high variance.

I was really keen to use P2Pool, and ran it for several months, but to be honest it was just too much - it needed a fast machine to run it, and payouts were pretty woeful. Half of any mining profits (if I got any at all) was wasted on power to run the i3 machine needed to make P2Pool perform anywhere near well enough.  I tried to run it on a Sempron dual core 2.5GHz CPU, and it struggled with a measly 5GH/s.  Someone said they ran P2Pool on a Celeron 847, but I think they were huffing glue.

Now I'm up to 35GH/s, I gave up on P2Pool.  I get far better returns with less bother on a 'real' pool.

When was that? Before or after the last protocol fork (which made it efficient with most ASICs) which happened in July? If it was after the fork it's surprising as it should have solved these problems.

BTW, your hashrate shouldn't have any impact on the resources used by a P2Pool node:

• Stratum offloads most of the work generation to the miner, leaving on average one computation to be done only when the node needs to update the coinbase (probably every 30 seconds on average unless it is aggressively pushing additional TX in the coinbase as they come, which would not be linked to the miners hashrate)
• variable difficulty is used so that the node only receives one share per second on average to verify

I use an i5-3350P with 16GB and a 64GB SSD with ~20 altcoins nodes, 6 p2pool nodes, a PostgreSQL database for some datamining and several other daemons with an average load at ~4.
My efficiency is most of the time >102% for the Bitcoin p2pool node with an Avalon and several FPGAs mining on it.

Before that I only had an old Core2Duo at 3GHz with 6GB and the same SSD which was more than enough. I upgraded due to flaky hardware (integrated SATA controller dying) and the additional RAM allowed me to follow more altcoins.

Edit: forgot to add CPU usage stats, on average the Bitcoin p2pool node uses 5.2% of one of my CPU cores, bitcoind uses 2.2%.

I will give it a try. Is ur guide the most uptodate?
