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

[spiccioli]

gonna take some time for the others to switch...

Additional 100GH for a day pointed on updated node will do the trick ;]
Do we know any1?

we could ask pyramining to point part of his farm...

My getwork latency is 0.211s mean. Had one spike up to 0.8s
I dont know if its good or bad. Whats your latency?
Also how can i optimize?

Well, the reason to have a treshold before switching to a fork, is, to have most of the users there.. "Cheating" with additional 100gh/s would be just like lowering the treshold.
We'll get there, fast! :-)

What's a normal 'age' for a share submission? After a weird issue with disk corruption I moved p2pool and bitcoind off of the miner hardware to an ubuntu install. getting from 5 to 10+ second 'age' times on 'Got Share' messages, with occasional 30-40 second ages. I'm presuming this is due to the lack of horsepower on the ubuntu system in processing and verifying the share against the chain. (Hint: it's a netbook )

Maybe I should swap to a low/no fee public node, instead.

The mean on my node is 0.152s, the highest in the "Day" graph is also about 0.8s,
but i have seen higher in the "Hour" graph.
It seems drop to less than 0.1s when a new block is found,
and goes higher and higher, so I guess it is a transaction scaling issue in bitcoind.

Edit: I mis-read the graph, the getwork latency only drops a little occasionally (when a block is found?),
so don't know why it goes higher and higher, then sometimes drops (about once per hour).

Is it possible and reasonable to run p2pool in a Raspberry Pi?  As I understand it, to run p2pool, you also need to run the bitcoin client to get the blockchain.  Here's my situation:

I'm currently running a BFL (FPGA) Single using cgminer on a RaspPi.  I do not use p2pool because of BFL's way of handling shares is not efficient with p2pool.

In the near future (hopefully), I will have 2 ASIC units that I would like to run on p2pool and I would like to use the RaspPi for this also.  So, although I can compile the source for p2pool and the bitcoin client, I am not sure if the RaspPi will be able to effectively run bitcoin. 

1) Has anyone successfully run p2pool on a RaspPi?

2) Is there a way to mine on the p2pool without running p2pool on the mining machine? 

3) Could I run the bitcoin client and p2pool on another computer then have my RaspPi w/ ASICs "point" to the other computer?  (Seems like a stupid idea.  At that point, I should just discard the RaspPi and simply mine on the computer.) 

4) Are there trusted nodes on the network that are running p2pool that I could point my RaspPi to?


Unrelated questions:  Does p2pool support stratum?  If not, will it soon or how will p2pool deal with the high hash rate of ASICs?

you dont have to compile p2pool, its written in python.
2. + 3. yes put bitcoind and p2pool on a other pc and connect from the RPI to it. this is not a stupid idea in case u want to have the miners outdoors, so u can have ur pc inside and the RPI + ASIC outside
4. search for the p2pool node list. but this is rather a bad idea due to latency, running it locally (or in your network) is the best idea.

no p2pool does not support stratum nor GBT yet, as far as i "know" the dev of p2pool, as soon ASIC comes out there will be a simple solution. stratum/GBT isnt good for p2pool anyways since the ~10 second Longpolls. I think hes going to implement a higher Diff Share system (the one already implemented isnt complete yet).

Doh - I knew about Python.

But if I do try to run everything on the RaspPi, I will also have to run bitcoin also right?  I will try it unless someone says it's crazy, but it would seem that it might be a bad idea.   (No HD for blockchain storage, only SD card.  Will this be too slow?  Will 256MB of main memory be too small?  Will the newer 512MB be too small?)  Does anyone have input for this part?

[stevegee58]

You can run bitcoind and p2pool on different machines.  I believe it's even suggested that you do that.

What advantage are you gaining running things on the RPi besides looking for things to do with your cool new toy?

you can run p2pool on rpi and bitcoind somewhere else, this works.
my bitcoind uses 168mB atm and p2pool 234mB so u would need the newer one (version B). as i said i recommend u to run p2pool and bitcoind somewhere else.

p2pminers are unionized, if they hear you talking about luck they'll take the week off.

It should have a mean of approximately 10 s, and be larger than 30 s about 5% of the time.

Low power (primarily) and low noise (low priority since FPGAs / ASICs are/will be noisy).  I see no need to run a PC or laptop for 50W to 150W (or so) when < 5W does just fine.

Thanks.  Due to memory limitations, I will try this.
