how to use p2pool for antminer S1 ?

Easy. Set miner url to the IP of the p2pool node followed by 9332 (example: 1.2.3.4:9332) and set your username to your bitcoin address.

can you suggest which url or the IP of the p2pool node?

mine.p2pool.com:9332

We are also pointing a TerraMiner IV at random addresses who are mining there for at least an hour a day to encourage people to use p2pool. 

Don't forget to set up backup pools.  Either various p2pool nodes, or some of the larger mining pools.

Started to get this error message:

No bitcoind connection when block submittal attempted!

Anyone encounter this before? bitcoind appears to be functioning correctly and the p2pool node does not seem to have lost connection to it.

Looks like it might have been bitcoind. Restarted and have not seen it since.

Good. :-). I was going to suggest that, but luckily checked the next page!

I'm just getting back into bitcoin, and used to use p2pool when GPUs were a thing. I have a small ASIC coming tomorrow (Antminer U2).

How foolish is it to mine on p2pool with _only_ 2 GH/s (gosh, it feels strange calling 2 GH/s "only")?

With such a small device I'm obviously not doing this professionally, but I'm also not sure what the variance will be like either.

The variance on 2GH on p2pool will, sadly, be massive. You could farm from sha256 alt coins though. Or else you might want to use a normal pool. (The proxy pool project I want to port to sha256 but haven't had time.)

Ok, thanks.

I was kind of fearing that, but it's good to get confirmation. I'll stick with a regular pool for now.

What difficulty are p2pool shares?

Edit: pypy Does not work:

Code:

Traceback (most recent call last):
  File "app_main.py", line 72, in run_toplevel
  File "./p2pool/run_p2pool.py", line 3, in <module>
    from p2pool import main
  File "/usr/home/P2Pool/p2pool/p2pool/main.py", line 17, in <module>
    from twisted.internet import defer, reactor, protocol, tcp
ImportError: No module named twisted

Ok, got pypy to work. as far as I can tell, the difficulty is that pypy does not like c-optimized python modules. I guess the FreeBSD ports collection has it's modules c-optimized by default.

The above error was resolved by running the following as the P2Pool user:

Code:

$ easy_install --user twisted
Searching for twisted
Best match: Twisted 13.2.0
Processing Twisted-13.2.0-py2.7-freebsd-9.2-RELEASE-p3-amd64.egg
Adding Twisted 13.2.0 to easy-install.pth file
...

I then got a new error message when trying to run P2Pool:

Code:

Traceback (most recent call last):
  File "app_main.py", line 72, in run_toplevel
  File "./p2pool/run_p2pool.py", line 3, in <module>

    raise ImportError(required + ": no module named zope.interface.")
ImportError: Twisted requires zope.interface 3.6.0 or later: no module named zope.interface.

In trial and error I tried easy_installing "zope.interface", "setuptools" and "argparse", but I am fairly sure this is what was needed:

Code:

$ easy_install --user -U  zope.interface
Searching for zope.interface

Adding zope.interface 4.1.0 to easy-install.pth file

It did not work without the '-U' option, which forces an upgrade (from upstream). In both cases, the '--user' option means that only the user running the command is effected.

Now to test if CPU usage/latency actually goes down

Update: Results are inconclusive or slightly worse.

Ok, thanks.

I was kind of fearing that, but it's good to get confirmation. I'll stick with a regular pool for now.

What difficulty are p2pool shares?

About 500K on average. Here's a 24 hour graph.

Thank you.

Some altcoin p2pool interfaces show a "time to share" but no BTC ones that I know of. You can use normal calculators though to put in your hash rate and the share difficulty to get an idea on how bad the variance is and if you are willing to stomach it. I have some smaller miners in my closest I've not touched in ages that are still happily hashing away with a raspberry Pi. I just check now and then they are still hashing and otherwise just ignore them.

I am using the stock one on my P2Pool node, and it has it:

Version: 13.4-16-g5ee3172

Pool rate: 130TH/s (16% DOA+orphan) Share difficulty: 425000

Node uptime: 12.2 hours Peers: 6 out, 4 in

Local rate: 10.4GH/s (28% DOA) Expected time to share: 2.0 days

Shares: 0 total (0 orphaned, 0 dead) Efficiency:

Haha I'm dense. I'm so used to running public nodes it didn't even occur to be a normal miner running their own p2pool will have the time to share on there. Doh!

What I was thinking at the time was how multiple miners on the same public node can't see their personal "time to share" unless the interface breaks that out and there is a patch to add a couple of required API calls to make that happen.

Roy7 is a bit math challenged. The variance in absolute terms (meaning the amount of actual coins you will be above or below expectation) will be smaller the smaller your hash rate.

If you are a very small miner you will be getting very little output no matter what. If you want to help bitcoin and also have some fun with your mining, just treat your p2pool output as a fun raffle. Every once in a while (maybe once per week, possibly more or less often) you will get a nice payout. The rest of the time you will get nothing. Either way you won't make a lot. Just relax and have fun it with.

[roy7]

Well then perhaps I'm using terms wrong. By variance I was referring to the # of shares on the share chain (how often he'll get paid being the concern, not the amount). At his speed he'll rarely find a share, so often blocks will pay out with no payment to him at all. As opposed to a normal pool with a tiny but steady stream of credit.

I thought the rate at which you receive payments was normally what people refer to as "variance" when we're discussing p2pool, and the issue with smaller miners on p2pool is the amount of time you'll have 0 shares when blocks are found, resulting in no payment at all.

Obviously the absolute amount of coins will be larger with larger hash rates.

However variance as a fraction of expectation is much greater when hashrate is lower, which I think is what roy7 meant, and what is generally noticed by most miners.

This is exactly what I meant by variance. The effect of having an excessively low hash rate compared to difficulty such that normal variances in finding shares have a drastic effect on the overall payout frequency of a miner.

Luckily my Antminer U2 arrived today, and I also placed an order for 10 more :-D

Thinking 22+ GH/s should be sufficient for p2pool :-)

Noticed, perhaps, if you are watching the pot boil. If you expect to make 50c/day and you make 0c/day, that looks like a big deal, but in reality your actual shortfall is still only 50c. Not going to hurt anybody.

Someone with a somewhat larger rig who expects to make $1000/day and makes $0/day (certainly possible when p2pool has 4+ day rounds), that's a $1000 shortfall, and may or may not be a big deal, depending on your financial situation.

At 22 GH you will still have dry spells on p2pool. As I said, though, don't worry about it, you'll have big payoff days too. Look at it every week or two and you'll be happy with the results.
