When you say that, either your calculations are incorrect, or you're wildly overstating a day of poor l***. As Emerald already stated, look over at least a week and not day by day.

That is realistic. I've been pointing 1/2 of my power at p2pool. I get between .9 and 1.2btc per block. I was one of the top 10 miners. I should be able to get between 4 and 5 btc per day. Lately it's been about 2, 3 on a really good day.
Um... if you expect 4 to 5 and you instead get 2 to 3, that isn't a 3 times difference.  I also think that day to day luck is too variable. Look at least at the last week's luck.
Right, but comparing p2p vs my other half on a regular pool I would have made triple what I did at p2pool. That's why I ran half of my miners in each place. To make a real comparison,not a guess. P2pools luck/variance sucked terribly or something else is very wrong. Even with merged mining it doesn't even out.

Namecoins aren't that valuable.  And the other ones are practically worthless.

I'm having problem (or not?) getting cgminer to work with p2pool

run_p2pool script is showing:

06-01 00:38:40.526000 P2Pool: 17451 shares in chain (8845 verified/17455 total) Peers: 10 (0 incoming)
06-01 00:38:40.526000  Local: 3364MH/s in last 10.0 minutes Local dead on arrival: ~1.7% (0-4%) Expected time to share: 9.8 min

06-01 00:38:40.526000  Shares: 2 (1 orphan, 0 dead) Stale rate: ~50.0% (9-91%) Efficiency: ~55.6% (10-101%) Current payout: 0.0

cgminer is showing over 1000 shares accepted after running for about  10 minutes

Should the output from run_p2pool show the shares that cgminer displays as accepted?

Are there any special settings in cgminer that I need to enable to make it work with p2pool?

No, actually, it's running just fine.  The shares shown in cgminer are not the same shares as in p2pool.  To really get any sort of solid numbers from the p2pool client, you need to run it for about 24 hours.

CGminer solves difficulty 1 shares (that places like BTCguild and Deepbit accept). In an effort to keep a 10 second share distribution spread, P2pool uses much higher difficulty shares (last I checked, it was like ~600).

P2pool is taking all shares close to 1 (0.99xxxx) but accetping to payout only shares higher than pool diff. Pool diff is calculated to make 1 pool share every 10 second. It was over 600 when 350GH pool, now about 450 on 200GH pool.
More miners -> more power -> higher payout share diff.
That near to 1 shares are accepted to keep you informed that miner is working - see yours stats page.
Also this log indicating that you just have started pool and it is still checking last pool shares Smiley
Try open ports to get incomming connections.

My node stats:

Thanks guys.  It makes more sense now.

My stats page is showing no incoming connections:
----------------------------------------------------
Pool rate: 230GH/s (10% stale) Share difficulty: 441

Node uptime: 0.094 days Peers: 10 out, 0 in

Local rate: 3.11GH/s (6.4% DOA)

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

Payout if a block were found NOW: 0.01130494 BTC to 1FNonVHWRn9H31ufEUe6w7w9ytMvxWq33Z

Current block value: 50.338125 BTC
----------------------------------------------------

I opened 9333, and tried external port scanner (http://www.t1shopper.com/tools/port-scan/)
it says the port is responding.  Is there something else I need to do to "publish" my external IP to p2pool to get incoming connections?

If you restart p2pool shares count is starting over form 0 Smiley
No worry, all you have shared is counted: you have payout > 0
Incomming connections will come over time, it is mostly 2-3 hrs after node start.
It should be port 9332 also if you want to connect miners from outside and allow other to see your stats Cheesy

Rav,

I'm confused, post #3 in this thread (step 9) is listing 9333 as the port to forward.

bitcoind is listening on 9332.  Should I be opening 9332 not 9333?
Did they mean to open 9333 and forward it to 9332, OR open 9332 and forward it to 9333, OR
open 9333 and forward to 9333, OR open 9332 and forward to 9332?

What do you have in your setup?

Thanks,
Peter
bitcoind uses 8332 for JSON-RPC and 8333 for peer connections, and p2pool uses 9332 for RPC and 9333 for peer connections. You should open 8333, 9332, and 9333 for a public setup, but not 8332. For a private setup, just open 8333 and 9333.

OK, after 1/2 years of p2pool mining I finally quit.

Simply because I don't get the reward I should get.

When I look at the luck chart it's always around 90%. And that pretty much confirms my own (long term!) observations: When using p2pool I get only about 80-90% of the reward I get compared to Slush or Deepbit.

Question: Is there any chance that p2pool will finally be able to compete with the other pools? Or is the p2pool approach simply inherently flawed?
Your perception is flawed, just as is most peoples when it comes to know where they stand in terms of coin generation. The only way your pool can make more than p2pool is if your pool solves more blocks for the same amount of hashing power. So the only factor that matters is how many BTC per gigahash you are making per day and actually receive. Which scoring system is used doesn't matter when you are trying to compare coin generation quantity per gigahash per day. To determine where you stand, you need a relative position, PPS, like with http://www.alloscomp.com/bitcoin/calculator.php is currently at ⊅.63 per day per gigahash. What percentage are you in comparison to this value with each pool?

Here are my stats from May 19, 12
I have only used p2pool:
Daily average = ⊅0.66846 per Gigahash
The current expected ⊅BTC for the difficulty 1733208 is ⊅0.58016 per Gigahsh
My daily average is 15.24% better than the current expected payout.

The total network is producing ⊅7450 per 24hrs for 11.91 TH/s. How many ⊅ per GH/s is that? It's ⊅0.62552 per GH/s.
That means the total network is paying out 8.4% better than expected.

Where you at?

Edit: This is where you are at in the last 24 hours:

In the past 24 hours Deepbit has found 18 blocks at 3177 GH/s, giving them a value of ⊅0.28328612 per gigahash.
In the past 24 hours P2Pool has found 5 blocks at 229 GH/s, giving them a value of ⊅1.09170305 per gigahash.

How much worse is p2pool now?

For Bitcoin to be a true global currency the value of BTC needs always to rise.
If BTC became the global currency & money supply = 100 Trillion then ⊅1.00 BTC = $4,761,904.76.

Given 100% luck, what would the BTC per gigahash be?

What about stats for the last 7, or 30, or 90 days?

So?

In the next 24 hours it might be the other way round.

I tested p2pool for 1/2 year!! - not just 24 hours. Or a week. I used it for full 6 month.

And I only got about 80-90 percent of what I would have gotten using BTC Guilds PPS method.

- With BTC Guild PPS I get ~0.48 BTC / day for my 840 MH/s.
- Using p2pool I got ~0.39 BTC / day (average for the past 6 month) for my 840 MH/s.

And no, I did not have a faulty configuration. Or old version (btw. this constant need for updating p2pool - and bitcoind - was a pain in the ass too. No need to worry about that using deepbit, slush, etc.).

If someone tells me he's getting the same or more using p2pool compared to a "traditional" pool he is simply a liar. Or fool. Or both.

Using cgminer I was getting 60-70% efficiency and 20-30 U/m. Configuration matters on p2pool.
-u bitcoinaddress+1  This helped to reduce D.O.A.
-g 1
-I 7

@Frizz23 Wow, both of your payouts are below the expected payout from Alloscomp's Bitcoin Calculator. Perhaps you have something misconfigured to get such bad results on both pools.

For Bitcoin to be a true global currency the value of BTC needs always to rise.
If BTC became the global currency & money supply = 100 Trillion then ⊅1.00 BTC = $4,761,904.76.

Are you sure about this?  Putting political views aside.

My cgminer shows slower hash rates for both GPUs and PGAs (that is probably ok, might be related to getting work from network vs local), but
my utilization dropped from the usual 48-49 (cgminer shares)/minute to 44.  The total hash rates as reported by run_p2pool and cgminer are much lower.
My cgminer queue grows, efficiency dropped to 30%.  Is this normal p2pool mining?  Something is OFF.  abcpool, btcguild, 50btc were running better.

I'll give it a try for a week or so (few blocks), but I'm not very impressed so far.  Maybe I'm doing something wrong.  I only have 1 incoming connection, 0.1 (possible) balance (on 3.3+GH/s) after few hours of running.  Both bitcoind (8333) and run_p2pool (9333) ports are opened.

Not sure what else I can do to improve.  Move the run_p2pool/bitcoind to another PC?

What i realized is that a fast CPU is very essential for good share results, if the used machine isnt working with the right capacity usualy there are more stales/DOA (especialy when you run p2pool and cgminer on the same machine for example). Yes to move the p2pool/bitcoind to an other machine could bring the solution in my oppinion. My efficiency is usualy above 100% MPBM seems to reduce my CGMINER hashingspeed aswell...

Because of fast longpooling efficiency shown by cgminer is much lower than on other pools (miner have less time to scan for solution).
Part of my cgminer.conf that I think can help:
Code:
"expiry" : "90",
"gpu-threads" : "1",
"queue" : "0",
"retry-pause" : "5",
"scan-time" : "60",
"submit-stale" : true,

After about 3 days of mining my cgminer shows:
Code:
cgminer version 2.3.4 - Started: [2012-05-29 23:07:52]
--------------------------------------------------------------------------------
 (5s):171.9 (avg):130.8 Mh/s | Q:31745  A:7467  R:70  HW:0  E:24%  U:1.72/m
 TQ: 0  ST: 1  SS: 0  DW: 30444  NB: 413  LW: 0  GF: 1  RF: 0
It is desktop PC, my kids (and me) are using it abut 12h/day ;]
I think 500-600MH/s card can give 100% (or more?) efficiency on my settings.

Hi together,

I'am new  to the P2Pool Project, but I will support the Idea.

So i have set up one Public Node and its ready to be used.

Who wants, ca Try it under

http://p2pool-cologne.dyndns.org:9332

The Stats can be seen on http://p2pool-cologne.dyndns.org:9332/static ,
The current Fee can be seen at  http://p2pool-cologne.dyndns.org:9332/fee

I'am new  to the P2Pool Project, but I will support the Idea.

So i have set up one Public Node and its ready to be used.

Who wants, ca Try it under

http://p2pool-cologne.dyndns.org:9332

The Stats can be seen on http://p2pool-cologne.dyndns.org:9332/static ,
The current Fee can be seen at  http://p2pool-cologne.dyndns.org:9332/fee


It's  an VM running on an VMware Cluster for HA at a location near Cologne / Germany.

The Server is also listed at http://nodes.p2pmine.com/


Have fun to test/use it

Well Done! Would love to see more p2pool Nodes in Europe Smiley

I only need People/worker who's use my node   Smiley

2 explanations for those not sure about things:

1) The E: value in cgminer really doesn't mean you are getting more BTC (higher E) or less BTC (lower E)
The easiest way to explain it is as an example.
This example isn't using exact numbers - in reality the E will be lower - but simplified for explanation.
... and by 'shares' I of course mean 1-difficulty pseudo shares as cgminer displays

A) If you have a computer with 2 devices that can each hash a full nonce range in 10 seconds (2^32 hashes) then on average (p2pool) it will complete each work item it gets and thus on average find 1 share per work item and have an E of 100%
B) If you have a computer with 4 devices that can each hash a full nonce range in 20 seconds (2^32 hashes) then on average (p2pool) it will complete only half of each work item and thus on average find 1 share per 2 work items and thus have an E of 50%

A) is of course 2 shares per 10 seconds and 2 work items per 10 seconds
B) is also 2 shares per 10 seconds but 4 work items per 10 seconds

Both the above computers have the same MH/s
Both of the 2 above will produce roughly the same amount of BTC
The second one just happens to get twice as much work to get the same result
There are other factors that come into the E value (e.g. roll-n-time) but the point is that E means how much work needs to be transferred to get your shares (not how many shares you expect to get over any given time frame)

2) Pool comparisons.
There is no point comparing pools over a day - that simply shows you don't understand how bitcoin mining works
Also saying "I got paid X BTC" in a short time frame (a day, a week or even a month) doesn't mean you will get that same amount the next day, week or even month.

Quite seriously, the only measurements of the performance of a pool that are valid, are:

A) the average of: "number of 1-difficulty shares" / "the block difficulty for each block found" ... over a LONG period of time (months)
 this is how you correctly calculate "LUCK" and should normally be close to 1.0 (100%) over a long period of time

B) the % of orphaned blocks

P2pool throws away share history ... so not everyone can check that.
Of course on P2Pool each share found actually counts for multiple 1-difficulty shares.
So if the current difficulty was say 650, then each share found while the p2pool difficulty was 650 would count as 650 "1-difficulty shares"
