This may have been asked or answered somewhere, but what happens when you receive subsidies, do you keep them for yourself or are they calculated into all the miners payouts?

Shit. Forgot about subsidies, my bad. I checked the transaction log.  Received 0.09092350 on Tuesday.  I will code in to credit miners for subsidies ASAP.  Thanks for the heads up.

The source is modified to only serve difficulty 1 shares.  P2pool calculates the hash rate based on the work submitted and I just log those hash rates at a regular interval and use that to calculate the reward distribution.  It's not as sexy as modding the code to capture actual shares submitted but it works out mathematically the same and it is easier to maintain as the p2pool code gets updated.  I'm just learning Python.  Once I examine the p2pool source some more and get more comfortable with Python, I will probably modify the code so that I can capture actual shares submitted, or I could just ask forrestv if he could just add that capability.

My pool works a little different from a public p2pool server.  My pool tracks the difficulty 1 shares submitted and then distributes the p2pool reward proportionally.  This is so your miner doesn't actually need to get a block on the p2pool share chain to get the reward (Great for low hashrate miners).  Current fee is 0.5% with auto payouts after a balance greater than 0.5 BTC.  See the thread https://bitcointalk.org/index.php?topic=66202.0

Who ever is mining with a Litecoin address, I would like to inform you that this is currently a Bitcoin only pool.  Make a transaction with your Litecoin address and PM me the amount(before you make the transaction) and send me a Bitcoin address to change your payouts to.  

Thanks

EDIT: Tittiez - it looks like it's you.

Fuck I copied from the wrong wallet. My BTC address is 1Pa8Wyp7LkxkPuRid6rXcLRvUCDZpGwA9W. What do you want me to do about the transaction? It was just one of those mornings...

Edit: PM'd you the transaction I made with my LTC address.

Your all set.  The all the payouts and current round work has been transferred to 1Pa8Wyp7LkxkPuRid6rXcLRvUCDZpGwA9W

Is it possible to turn off dynamic share difficulty for local shares?

Quote
New work for workers! Difficulty: 9.8273 Share Difficulty 635.184144

I don't really see the point of this.  Even at 10GH/s locally the amount of miner traffic is minimal and it is on the LAN.  Keeping shares difficult 1 locally allows apples to apples comparison at the miner level.

With dynamic difficulty changing I just realized it made comparing stats (in cgminer) between rigs with different uptimes impossible.  cgminer reports total # of shares but those shares represent different amounts of work.    I was comparing mem clock difference between two rigs and the stats are junk.  Stupid me for not thinking of this before running the trial.

Is there a command line argument to specify a static local share value?  If not can it be included in the next version?



If you comment out line 533-538 in the main.py file (newest version) it will serve only diffficulty 1 shares to your miner

See before and after below.

Before:
Code:
                target = net.PARENT.SANE_MAX_TARGET
                if len(self.recent_shares_ts_work) == 50:
                    hash_rate = sum(work for ts, work in self.recent_shares_ts_work)//(self.recent_shares_ts_work[-1][0] - self.recent_shares_ts_work[0][0])
                    target = min(target, 2**256//(hash_rate))
                target = max(target, share_info['bits'].target)
                for aux_work in current_work.value['mm_chains'].itervalues():
                    target = max(target, aux_work['target'])

After:
Code:
                target = net.PARENT.SANE_MAX_TARGET
                # if len(self.recent_shares_ts_work) == 50:
                #  hash_rate = sum(work for ts, work in self.recent_shares_ts_work)//(self.recent_shares_ts_work[-1][0] - self.recent_shares_ts_work[0][0])
                #  target = min(target, 2**256//(hash_rate))
                #  target = max(target, share_info['bits'].target)
                #for aux_work in current_work.value['mm_chains'].itervalues():
                #    target = max(target, aux_work['target'])

So this pool actually serves up Difficulty 1 shares? Or is it just a P2Pool node set up and opened to everyone?

As I understand, difficulty 1 shares. At least that's what I gleaned from the OP.

I made an error but it is now fixed.  P2Pool starts off serving difficulty 1 shares to miners, but as the local P2pool hashrate(P2P Mining Hashrate) increases, so did difficulty. I modded the P2Pool code to now always serve difficulty 1 shares so that it works as described in the original post.

I also fixed some bugs in the Miner list page so that a miner's address will show up even if they haven't submitted work in a while.  This way they can still go to their payout page.

I just wanted to give people a way to contribute to the P2Pool hash rate easily and with less variance. I also want to develop a better user interface for miners to monitor statistical data. It is also a way for me to start my own pool with low initial hash rate and low variance.  I may release the code in the future so others can have there own P2Pool pools. It's just a few PHP scripts and a database on top of P2Pool and Bitcoind.

I have started a new kind of pool that is a sub pool of P2Pool.  With this pool you don't need to get your own block on to the P2Pool share chain.  I track all shares that are submitted by miners and divide the next P2Pool share that my pool receives proportionally to shares submitted in past 24 hours.  

Small miners can now mine on P2Pool and be sure they will get at least some portion of the next P2Pool block that is found.

I have multiple miners mining at one p2pool server. Each miner has it's own bitcoin address. 

How is the payout split to each bitcoin address? 

Does each miner need to find blocks added to the share chain or is the payout split to the addresses based on work submitted to my p2pool server? 

Thanks
391  Bitcoin / Mining speculation / Re: Countdown To 25 BTC / Block reward on: February 14, 2012, 09:18:18 PM

but it could be wwwaaayyyy off depending on the market.


scenerio: 
1. price of bitcoins shoot up
2. lots of miners start to mine,  diff shoots up
3. price hits 2
4. miners leave in droves

now it takes 20 minutes on avg to find a block.


what is the actual launch date of BTC?, and how close are we to the projected 25btc date?

From my calculation,  We are only off by 2.12 days @ 10 minutes per block from the genesis block start date.
392  Bitcoin / Mining speculation / Re: Countdown To 25 BTC / Block reward on: February 14, 2012, 06:48:22 PM
You don't know what day it will happen, so how can you have a clock like that?

this one is acurate.  when the hour hand hits twelve, reward will be cut.
http://bitcoinclock.com/


It is an estimation based on 10 min per block.  It pulls the current block number from blockexplorer.com. Just for fun.

That other clock is pretty cool Cheesy

The reasons for choosing 277VAC are:
a) Still only one phase to worry about - not two or three per PSU. Less wiring.
b) No 480 --> 240 VAC transformer losses. (Not sure how much efficiency loss there is, but I don't think the transformer could be any higher than 96-97% efficient. Mine is a 45Kva SquareD)
c) Smaller gauge wiring due to the higher voltage.

Well "a" doesn't really matter.  If you home isn't 3 phase you aren't getting 3 phase anyways.

On "b" I think you are forgetting about the 480 -> 277 VAC transformer. Wink Still transformers tend to be very efficient.  97%+ is certainly likely, 99%+ is possible.   Energy in = Energy out.  So all the energy on the 480 VAC side becomes 240 VAC or heat.  An inefficient transformer on a mains where it could be pulling 100 amps+ would quickly melt.  Some quick numbers.  The transformer is rated at 45KVA so at 5% inefficiency and peak load ~2.5KW would be converted into heat.  Heat output on the transformer would be more than 10x 5970s. Smiley

Optimally the best thing for you would be a high efficiency 5KW 480VAC to 12VDC powersupply.  You could power an entire rack of GPUs.  Smiley  Then just run the low wattage mixed voltage components off some low wattage ATX PSU units.  Now if you found and rigged that you might be a serious miner.



b) 480V three phase is 480V leg to leg and 277V to ground. If you want to run 277V, you would need to have a 4-wire service.  The kind of tr

Very nice - what are you using to generate the charts?

Thanks.

I am using the Flot plugin for Jquery.

I was thinking that you could set up an api where I can send a request with POST data in a variable called 'bulk_users'.  The data would be JSON encoded as follows.

{"users":[{"api":"user1api","action":"userstats"},{"api":"user2api","action":"userstats"},{"api":"user3api","action":"userstats"}]}

would that work?

Just completed a webpage for charting hash rate of my miners.  I set it up so anyone can enter their API and chart their own hash rate. Is anyone interested?  If there is a lot of interest I would like to get Inaba to set up the api so I could grab multiple users data in one HTTPS call.

Here is a link to my webpage for tracking your hashrate. I put my API here to show an example. More graphs and features will follow.
