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

[PatMan]

.....the p2pool client is actually completely native and unmodified (for now).

Oh? Are you planning something?  (Please say yes  )

1000 hours to rewrite p2pool eh - what's your hourly rate? 

[naplam]

Who runs http://p2pool-nodes.info ? how can I tell them to list my public pool?

It will find your node automatically - might take a few days to propagate 

Hmm I changed IP but the old one isn't there either and it had been running for weeks, that's why I thought it was somehow manual (or malfunctioning).

How does this differ from pointing all the workers to the same workername on the same node, all with high difficulty?

The p2pool client software has to generate multiple workers of multiple different data sets and track them all, and then process the shares as they come in. Setting the difficulty high only helps that latter part (the shares) which is actually the least work. If python wasn't single threaded and as inefficient as it was compared to a low level language, this workload would be irrelevant over and above the work of communicating with the p2pool network and the bitcoind to generate work, but it's not when everything is serialised, so there are always bursts of worst case latencies which are real-world problematic.

Excellent point.

I have a new node as well, ireland.p2pool.co, which has been running for almost a week and it is not showing on p2pool-nodes.info as well.  If anyone knows how to contact the operator or what you have to do to get on this list please let us know.  Thanks!

Try peering with a couple connected nodes...

I.E. Find a couple or few close nodes that are connected and add them as nodes using -n when you start a p2pool process.

Bleg!!!


I updated my linux system... Bad mistake.

Now I am getting these errors trying to start my p2pools!

Traceback (most recent call last):
  File "/opt/p2pool/run_p2pool.py", line 3, in <module>
    from p2pool import main
  File "/opt/p2pool/p2pool/main.py", line 17, in <module>
    from twisted.internet import defer, reactor, protocol, tcp
ImportError: No module named twisted.internet


Help please!!

I have the same issue when I use pypy but not python, "ImportError: No module named twisted" even though twisted is installed.  I have tried everything including re-installing twisted and re-making p2pool.  I also copied twisted into python2.7 from dist-package.  Any other ideas?  Thanks.

You don't need to make p2pool, it should just run from the directory. I would suggest deleting it & uninstalling what you installed & try again following the read me. What version of Linux are you using?

How can I edit for altcoin with p2pool ?

I would ask in the altcoin thread that you want to mine.

Rav3nPL has a version in git for altcoins

Thanks for the reply.

I am running Ubuntu 14.04

I actually fixed it after spending quite a bit of time on it.  I needed to copy zope and twisted from /usr/lib/python2.7/dist-packages to /usr/lib/pypy/dist-packages.

Also, to note, (and it seems obvious now) that you need to run p2pool with the option --relay-network public.us-east.relay.mattcorallo.com.  Assuming, your server is on the east coast of the US.

No worries, glad you got it running. You're much better off running the C++ binary for Matts relay node, the python one is veeeeery slow. Again, no need to build it, it runs separately from within the client directory

Please sir, can I have some more?.........

Let there be some seconds between please, that last was ~0.6s after discus fish found one..

[MissouriMiner]

请使用正确的难度。
P2POOL，这15天效率很低，
原因：中国矿工约有1.5PH/S，使用了超大的难度（+5120或者更多），
我们及时的更改了错误，目前全部使用大约是难度比例1:1。
P2POOL这些天低效率，我们表示抱歉。
但是我们认识到了最好的难度选择是：选择和矿机算力相等的难度。
当前我们的蚂蚁S3+518（+512，S3不显示BestShare），
1TH/S+1028，

S3+518，平均5秒一个Accepted。

S3+5120，大部分计算都超时，被服务器拒绝，能挖到的Share，但是很难产生块。

希望这些数据能帮助到更多的P2POOL矿工，

使用正确的难度选择。

Please use the correct difficulty.
P2POOL, this 15 days the efficiency is very low,
Reason: the Chinese miners about 1.5PH/S, using the large difficulty (+5120 or more),
We amend the wrong, all currently used is about difficulty ratio 1:1.
P2POOL these days and low efficiency, we apologize.
But we recognize the difficulty of selecting the best: the selection and calculation of force is equal to the difficulty of mining machine.
Our current ant S3+518 (+512, S3 does not display the BestShare),
1TH/S+1028,
S3+518, an average of 5 seconds for a Accepted.
S3+5120, most computing timeout, was rejected by the server, can dig into Share, but it is difficult to produce block.
Hope that these data will help to more P2POOL miners,
The use of the difficulty of choosing the right.

Do you have a recommended optimal setting for the S4?  I am using +2048, and it seems to be working OK.  What are other S4 owners using for pseudo difficulty?

[nreal]

Pseudo share doesnt affect in founding block anyotherway than it restarts works everytime that changes, so selecting constant could help abit keeping miner busy. Large miners should use bigger sharedifficulty - that would help poolwide. Like btcaddress+501/100000000, then there should be less 5 s restart times, and big miners earn that way more too. Ckolivas proxy helps keeping miners busy also, I have got very good results with it in p2pool and solo pool, it squeezes juice out of miners, with s3s mindiff and startdiff have to be chosen so that you can see best share..

Last weeks bests with 2th= 2,347,645,293, one ~1,500000000,   537,352,921 .. newer got those kind of results without proxy.

S3:s doesnt show best share with all share diff + 512, 1024, 4096 doesnt show, 500, 4000 ... it shows

nohup ./ckpool -p -A -k> /dev/null 2>&1 &

Wondering how ants would perform if those are turned to diskless nodes and booted with tftp, that way cgminer could be running on some more powerfull machine, i think s2 s3 s4 are suffering constan restarts - the mainoboard doesnt have enough power. And that way I doesnt have to wait new firmware and cgminer...

Did you manage to get the S4 working with p2pool? I saw the test results when Bitmain tried it with IYFTech's node & they were terrible, are you using the latest code from ckolivas? Any improvement?

Peace

My latest binary works a bazillion times better on p2pool.

The default Bitmain 4.6.1 has been working pretty good for me.  I get 1.9 TH/s average.  And you have to set pseudo difficulty.  It doesn't work properly without it.  I haven't tried the latest version from ckolivas that was released within the last 24 hours, but I will try it now.
