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

[ddd1]

I'm considering changing pools but I'm not wery computer savy person.

I use guiminer and deepbit because it was easy to setup for a windows user, is there any chance for me to use this pool or is it just over my head when it comes to setting up mining here?

It's pretty simple; just look at the guide in the third post in this topic for Windows.

Or if you want, you can mine on my P2Pool node: http://tjberens.ath.cx:9332 (just connect with your payout address as your username and any password (or use "graph" for your password if you wanna see yourself on my graphs)) I put a 0.5% fee on it.

thank you I will consider it if the instructions are over my head for windows.

1. I briefly went over the information, so basicaly this is a collection of everyone mhash into the pool and evenly distributed according my mhash mined relative to the pool and accuired bitcoins?
So this decreases the variance for me to solo mining to the variance of 270ghas/s?

2. Also it is 0% fee?

3. So is this pool basicaly a solo mining with the benefit of having less variance/luck factor?

There is a precompiled binary version of p2pool it makes getting it up and running easy.  If you have bitcoin wallet installed and working you simply need to
a) run bitcoind (found in bitcoin program folder)
b) run run_p2pool binary
c) point your miners to the machine running p2pool like you would any other pool.

Yes.  It is the same as a "normal" 270 GH/s PPLNS pool.

2. Also it is 0% fee?

Yes although you can turn on donation % for the developer (or manually donate).

3. So is this pool basicaly a solo mining with the benefit of having less variance/luck factor?

That is one way to look at it.

Yes although you can turn on donation % for the developer (or manually donate).

Actually, there's a 0.5% default donation. Anything else (no donation or more) needs to be specified.

I'm pretty sure the donation feature was removed a while ago. 

Other than that it should be 50BTC divided proportionally, minus the small bonus for the person who found the block.

Why do you need Python 2.7? I'm running p2pool on 2 debian systems with Python 2.6 just fine.  Theres a couple depreciation warnings, but those don't hurt anything.

Uhm, good question..
I dont even remember why I thought I need 2.7 to begin with? I uninstall it now and see if bitcoind and p2pool etc still work..
Thanks for the hint, sometimes the easiest way is the, well, easiest? :-)

The wiki still says:

Code:

  --give-author DONATION_PERCENTAGE
                        donate this percentage of work to author of p2pool
                        (default: 0.5)

If that's the case, somebody forgot to tell run_p2pool.py - the usage output still mentions it. See kano's post for the exact wording.

main.py
    parser.add_argument('--give-author', metavar='DONATION_PERCENTAGE',
        help='donate this percentage of work to author of p2pool (default: 0.5)',
        type=float, action='store', default=0.5, dest='donation_percentage')

data.py
    # 1 satoshi is always donated so that a list of p2pool generated blocks can be easily found by looking at the donation address
    amounts = dict((script, (subsidy-1)*(199*weight)//(200*total_weight)) for (script, weight) in weights.iteritems())
    amounts[new_script] = amounts.get(new_script, 0) + (subsidy-1)//200
    amounts[DONATION_SCRIPT] = amounts.get(DONATION_SCRIPT, 0) + (subsidy-1)*(199*donation_weight)//(200*total_weight)
    amounts[DONATION_SCRIPT] = amounts.get(DONATION_SCRIPT, 0) + subsidy - sum(amounts.itervalues()) # collect any extra satoshis
   
Looks like there is still a default to me. (From 1f87c32)
Plus looks like a really small amount is donated whether you turn it off or not so that a list of blocks can be maintained.

5 blocks in two weeks, I must be in lucky mode. My farm is 7.5GH/s and only part of it allocated to p2pool.

So I see the variance is still pretty noticeable... Would anyone be willing to share rough weekly/monthly profits and their mhash which is pointed at p2pool? I'm one of those seeing is believing kinda guys. When I was just mining one gpu, I was getting about .03 more/day than I would have on PPS/Prop at a big pool with fees, so I was happy, but now that I'm on 4 gpu's and over 3x more mhash (1350 now), I'm just curious as to if I will still make my calculated (based off of BTC calculators and such) ~.9BTC per day?

You can see the recent luck on the p2pool.info stats page.  You can determine what any miner made by doing simple math with those values and any bitcoin mining calculator.

For example, a 1GH/s miner would earn 0.67 BTC/day if they have no variance.  You can see that p2pool has been unlucky recently and in the last 7 days, the pool has found about 65% of the blocks that would have been expected if the pool had no variance.  So that 1GH/s miner would actually have made 0.67 BTC/day * 0.65 = .4355 BTC/day over the past 7 days.

Of course on weeks that p2pool is lucky, the pool will find more blocks than expected if there were zero variance and that miner would make more than 0.67 BTC/day. 

Over a long period of time, the good weeks will tend to offset the bad weeks, etc.

Notice: The protocol switchover happens in 9 hours. If you haven't upgraded to the latest P2Pool, you should do so now. The first post has binaries for 0.9.2.

A few errors ending like this are expected 1 hour after the switch time, since there will inevitably be a few nodes that haven't upgraded:

2012-02-26 02:31:41.256425 >     raise ValueError('old share an hour after switch time')
2012-02-26 02:31:41.256481 > exceptions.ValueError: old share an hour after switch time

Any node that sends invalid shares is banned from connecting to you for an hour as of P2Pool version 0.9.1. This will minimize the impact of un-upgraded peers by splitting them off from the main P2Pool network.

I don't think cgminer splits 1 single getwork across cards.  I am pretty sure it does 1 getwork per thread (so if you are running 8 GPU w/ 2 threads each it pulls 16 getworks).  That would be one useful optimization in cgminer. 

Correct. cgminer really needs a work splitting engine, badly.

This is not remotely true. The only time you may have difficulty getting enough work is immediately after a longpoll, and that is precisely when cgminer splits work. Furthermore, with p2pool, your local p2pool node can generate enough work for 100s of GPUs and cgminer is not remotely a rate limiting component.

You should upgrade your bitcoind to support P2SH!
