I see an influx of hashing power on the horizon from BAN - those poor guys are starting to cotton on by the looks of it......maybe that'll help break this block Wink
Maybe... but the vast majority of people mining on pools where they can set payout thresholds, only need to wait a few confirmations and so forth will just fail to understand p2pool.  They'll come, get angry that they aren't getting paid every 2 hours because their ADHD is kicking in and they're getting twitchy Smiley

This is how it's always been - but there are always some who get it & stay. We get the cream........ Cheesy

Heh, good way to look at it.

Come on Mr. Block, come out of hiding! This is getting depressing!

Ok you Linux gurus I have a question, 

I just setup a new node on Debian.

I had to run Bitcoin-qt cause i could not the bitoind to auto start on server boot. with the Init.d setup.  Very strange.  And i hate having to rememeber ccli scripts to move coin in and out of the default wallet.  Lol never had to yet.

Any suggestions on how to setup the auto start for bitcoind and python scripts for p2pool.

Also I was interested in pypy as some of you said things run faster on it.  I have 12 GB ram in the server machine.  So i have plenty.

Thanks for your assistance.

Do you have bitcoin.conf created in ~/.bitcoin directory and it contains
Code:
daemon=1
server=1
rpcuser=something
rpcpassword=somethingelse
?

Yes

I can start it manually and run it with the -daemon setting and it runs fine that way.  This is my second node i have setup so i do understand the mechanics of it.

It is completely running just need to get the autp start on both bitcoind and the python scrips to auto start on boot

Finally found a use for "/"...

The past few days I've decided to rent some pretty significant firepower for p2pool.  Although it hasn't helped us solve any blocks, it has certainly given me some interesting data points to consider.  Thought I'd share with the class Smiley

Normally I've got 9 S3s pointing to my p2pool nodes.  The past few months, I've had a couple redirected to OgNasty's node for a test, but they're all still on p2pool in some fashion or other.

The past few days I've rented anywhere from 200 - 400 TH/s of miners.  I've pointed that hash to my node and have tried a few different combinations of settings to see what happened.

My S3s I have configured like this: "ADDRESS+500".  They have remained constant with that setting.
The rentals I've done a bunch of stuff to see what effect it would have on my S3s.  Here's what I've found:

ADDRESS/4096 (or any /xxx where xxx is less than share difficulty): the node will ALWAYS set the share difficulty for this worker to be the standard p2pool share difficulty.  So, if p2pool has a difficulty of 10,000,000, that's what the difficulty will be for this worker.

ADDRESS: Not using the "/" sets the difficulty for this worker based upon the node's hash rate.  What I've found is that it tries to get the time to find a share around 30 minutes.

ADDRESS/50000000 (or any value higher than share difficulty): As you'd expect, if you provide a value higher than p2pool's difficulty, the node sets that difficulty for your worker.

So...

If you're a miner and you're on a node where the node's total hash rate is significant, and you're not the source of that high hash rate, you should use some value for "/".  Why?  Because that miner with the high hash rate might be relying upon the node to set the difficulty, which will hurt you in terms of time to share.

If you're the miner who's got the extremely high hash rate, do the rest of the miners on that node a favor and set your share difficulty high enough to ensure you're not submitting shares more often than every 30 minutes or so.  It's pretty easy to calculate this value:

Code:
Difficulty * 2^32 / hash rate = time to share

Therefore, to get the difficulty if you've got 200TH/s:

Code:
Difficulty = 1800 * 200000000000 / 2^32

So, if you've got 200TH/s, you should set your difficulty to 83819031.

Anyway, food for thought while I'm sitting here at the airport waiting for my delayed flight to take off Smiley

Hey guys, i made my own node and started mining. But i cant figure out how to set the diff for the ant s4. i tried puting worker.1+2054  but the diff stays at 1000. Should i change the diff for the s4 or should i leave it? btw i have the newest firmware from bitmain

i believe what you;ve set is the "+" which is known as pseudo diff, max is 998.99xxxxxxxx, you can only set lower than max 998.999xxxxxxx so for a s4 or miners that is above 1ths, there's no need for it except for smaller miners like s3 where you will set +512 or any other value.

you might want to set queue to 0 or 1 by ssh'ing in.

welcome to p2pool & happy mining.

Thanks man, now im gettin the diff Smiley, anyway my queue is 1. and with 118% Efficiency. So far two shares Tongue

FYI - The max was increased in a p2pool build (forrestv) back in Aug.  The new max is 1000000 (1 million).  For my S4, I use +2240.  If you use a multiple of 512, the best share value does not populate.  So I use +518 for S3, +1028 for S2/C1/S5, and +2240 for S4.  However, the pseudo-difficulty values do not effect your shares or payout. Those new shares are just good luck.  :-)

ok started the node, everything is good except some of the time bitcoin-qt make so much upload that kills my internet latency. I installed netlimiter and limited the up stream to 150kb. How can i restrict the upload only for the ppl that pull the blocks and not to the p2pool? is that affecting my income for my node? thanks

people lost interest in p2pool? pool rate was 3ph+ in dec-jan, now its 1.5-2.5 PH max. Also dont know who is the big guy who comes in and goes out now and then. I see big deviation from 1.5PH to 2.5PH frequently. why arent the miners staying at the pool or pool has some problem?

Very true, also keep in mind pool rate is a very rough estimate based on submitted share and will always have a pretty large swing, 1PH swing up and down for the estimate is pretty typical...

Take a look at the historical charts on windpath's site: http://minefast.coincadence.com/p2pool-stats.php.  You can see the hash rate and active miners reported up to a 6 month window.  We can certainly see a downward trend, and I think this can be explained by more and more home-based miners turning off their equipment as difficulty has risen and value has dropped.  The big guys (i.e. those with multiple PHs of gear) are typically not mining on p2pool, but rather are likely to run their own pools.

Let's face it, mining in p2pool is pretty much a niche market experience.  While we all (members like PatMan, windpath, IYFTech, myself who have been here for a year or longer) espouse its value and praise its decentralization, the reality is Joe Sixpack miner can't be bothered to setup and run his own node.  Furthermore, most of those miners can't handle the inherent variance in p2pool.  They like their steady little trickle payouts and naturally migrate towards the large, centralized pools.  

This thread is full of discussions amongst members about what needs to be done.  Solving the variance problem.  Making running a node more user friendly.  Making p2pool more performant by rewriting it in a language other than python.  In my opinion, decentralization is the single most powerful feature that p2pool brings to the table.  Unfortunately, p2pool has no active development effort, and hasn't had it for a very long time.  Yes, there are a number of people who have stepped up to provide some great front ends and data availability (rav3n, justino, windpath, nonnakip to name a few), but the core code itself is in need of attention.  The original developer has had little to no involvement with the community and nobody in the community has stepped up to take over the project.

If I had the time, I'd love to organize a hackathon.  Unfortunately, Bitcoin mining is a hobby and my own schedule prevents me from taking on a larger role.  I'm sure a lot of others of us here are in the same boat.  Oh well, when I win the Power Ball tomorrow, I'll have plenty of time on my hands Smiley

If you're suffering from Bitcoin sucking your bandwidth, use the "maxconnections=n" (n=whatever number you like - try 14 or 12) command in your bitcoin.conf file  Smiley

Same here.  And, honestly, if I had the time ... there are lots of things I'd be doing before rewriting p2pool.
