What could be worng if the local hashrate is higher than total p2pool hashrate ? ;/
March 01, 2014, 05:19:41 AM
Has anyone ever seen their P2Pool show "no shares yet" under the Active Miners on This Node?
I am seeing this on my Bitcoin P2Pool, also I am seeing the entire pool hashrate has dropped steeply to 99TH/s.

I've put in a pull request to fix the problem with vardiff sending out 0 diff work that causes some GPU miners to spew endless HWs.

I got an error where it said something about trying to broadcast a share without having all the transactions (?). Then the share was counted against orphans, I think. The message scrolled off before I could save it. There's no log file for p2pool right? At least I couldn't find it.

Part of the problem may be that python is an interpreted, not compiled language.
I have seen compiled versions of p2pool (at least for windows in the OP). Anyone have instructions on how to do so? I'm not so much interested in increasing the performance as making it easier for others to use without having to load dependencies.

Hi guys, do you have any idea what might be causing this hashrate drops on my p2pool ?

I was going to guess no internet until you posted the error log.
"0197 > Failure: twisted.internet.error.ConnectBindError: Couldn't bind: 24: Too many open files."
suggest you should look into raising the number of file descriptors. Have not run into that problem myself yet.

if I run my own p2pool node how do I change to ADDR/0.001?
is there a switch in run_p2pool to achieve this?
when i do run_p2pool -a/0.0001
it gives me a parse error

Is it the username your miner uses to connect to a node. Instead of username = payment address, use ADDR+DIFF to control the pseudo share difficulty (for graphing or support really old asics) or use ADDR/DIFF to control your share target. You can also use both. For instance I mine Uno (a sha256 coin) with ADDR/64000+64 on my Antminer S1 (180GH).

Hi! I have the following problem. Sometimes, if the restart p2pool (quark-algoritm), when the power pool > ~ 150 MH / s, process starts to load the processor to 100% and all shares the dead. All logentries "DEAD ON ARRIVAL". Why this happens and how to solve this problem?
If it takes your node more than 30 seconds to verify a block, you will get 100% stales. Even without 6 different hashing algorithms, I have seen up to 12 seconds of CPU lag on my machine processing P2Pool.
Part of the problem may be that python is an interpreted, not compiled language. A Just-In-Time compiler like PyPy may help. (I think I will test that on my own machine)
Edit: I think actual block processing is handed off to Bitcoind. P2Pool still has its own chain though.
Edit: pypy Does not work:
Code:

Update:
Got it working.
February 27, 2014, 05:57:42 AM
Individual miners on a public node would see reduced variance in their own shares, since pool hash rate is taken out of the equation. They could do this by hand now with ADDR/1 (or say /.000001 for scrypt), but I think handling it automatically makes more sense (and keeps vardiff alive for miners that are maybe bigger than justifies using ADDR/1).

I'm thinking of setting a P2Pool node up for around 2MH/s on Vertcoin. Can you still auto donate 1% to the dev's?
I don't think Forrest has a Vertcoin address but you can ask him. The address hard coded into the repo wouldn't work anyway. Maybe best to just do a manual donation now and then to his BTC address.

For those interested I just found an interesting patch the author mentioned on the HHTT thread:
https://github.com/iongchun/p2pool/tree/auto-worker-diff
Gives you two command line options to control the pseduo share difficulty. You can set a target difficulty per-miner or per-address. Using that per-address would seem to fit nicely with my pull request to set share difficulty based on address speed instead of local node speed.

Fee % isn't a % of each block. It is a % of shares are randomly given to you instead of your miner. So in 100 shares, on average, 1 share will be 100% credit to you, and 99 shares will be 100% credit to your miners. It should average out long-term that you make 1% of the total income of the pool. But it is very high variance. I hope in a future major version of p2pool the fee % is applied to every block like donation %.
February 26, 2014, 03:24:15 AM
Hi guys, is there a way to check why I'm not getting fees from every mined block (and the total fees are much lower than the set 1%) ?
Right now avarage payout of two biggest miners only is ~4000BC, but I'm not getting any fees ;/ (It's not about greed - I just don't understand it).
Hashrate is constant (and growing).

Hashrate is constant (and growing).
I had the same question in another topic:
Should you get a 1% fee everytime the miners are paid? I haven't received any fee yet, while the active miners have received their share payments.
Or will this fee be paid on a daily base? I got the feeling something is setup wrong.
Or will this fee be paid on a daily base? I got the feeling something is setup wrong.
It isn't intuitive, but each share a miner submits to you has a 1% chance of becoming your share instead. So you'll see a lot of variance in your pool fee income, but long-term it should even out (at the expense of higher variance for the miner as well).
Maybe one day p2pool will allow the fee amount to be recorded in the share, like the donation amount is, so it can be paid exactly when each share is paid and all shares remain with the miner.
After a few weeks I can confirm this behavior. Sometimes there are days without a fee, and then suddenly you get a few in a row. Looking back a month it seems to be about 1%!
It has also happened to me. I need like a couple of months to understand what is going on until I read on post on the site (another subforum) and finally understood what's going on
