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

[btharper]

IMO it is your bitcoind lagging, try latest git https://github.com/bitcoin/bitcoin

Thanks a lot!



A slight difference.

Wow, for those who don't care immediately to check the image, the "slight difference" is an order of magnitude.

Also, have you thought about adding your P2Pool node to nodees.p2pmine.com? Just another way to advertise, I believe there's also a thread (maybe more than one) that archives a large list of nodes

It is only 10x faster ;]

Does it support merged mining like namecoin, or separate pool?

Probably it's own network.  I was poking around myself a couple days ago to see if it would work with PPCoin.

Memory usage still very high:
651MB virtual, 490MB physical. Probably that's why it's loosing contact with bitcoind (swapping memory).

[lenny_]

Yes, a little bit smaller usage in your machine. Your biggest p2pool instance eats 359 MB RAM (564 MB virtual).
At this moment, my p2pool memory usage decreased to 442 MB RAM (651 MB virtual).
P2pool is first time since v9 - usable, it not losing contact with bitcoind anymore, look at graphs: http://lenny.dnsd.me:9332/static/graphs.html?Hour

[mdude77]

I think using the latest bitcoind is a bad idea.

Here's why.

I fired up bitcoind in my linux vm.  Pulled the latest git of p2pool, and pointed it to bitcoind.  Pointed all 3 of my miners (measly 4.5GH/s) to it.

Within 30 minutes I had 4 shares, all orphans.

I changed p2pool to point to my local official build of bitcoind (7.1) and restarted it.

Two hours later I have 7 shares, 0 orphans, 0 dead.

Granted, it could be coincidence.  But the latest bitcoind does say "do not use for mining".

[lenny_]

I am not using my node for mining, just for supporting network as 24/7 peer.
Did you make sure that your bitcoind from git had latest blockchain? Files are different from 0.7.1 and may be not compatible when you switching versions with same ~/.bitcoin directory.

EDIT:
Memory usage is really low now:) I left p2pool overnight, and after 12 hours of running, it establish connections to Peers: 5 out, 4 in. Physical usage 296MB, virtual 440MB. Well done, forrestv! I still can use p2pool on my 1GB RAM machine, I will leave it running:)

Yes.  Blockchain pulled it from that build only.

[Proofer]

Where in my linux p2pool directory can I look to find the human-readable version number, e.g., currently, 9.4?

[twmz]

Granted, it could be coincidence. 

A handfull of shares are far too few to identify statistically valid patterns.

My stats for the past couple days with the latest bitcoind...

Code:

Shares: 137 (8 orphan, 1 dead) Stale rate: ~6.6% (3-13%) Efficiency: ~110.8% (104-115%)

Try editing your bitcoin conf with the below settings. The reasoning behind them is with less connections and less transactions to process your bitcoind will respond faster. It did help a lot for me. Also I've noticed that anyone compiling their own bitcoin from git has a big advantage too since the new db system for the next bitcoin release is way faster. If you can't compile your own keep an eye out for a 0.8RC1 when it comes out.

Code:

maxconnections=10

#Maximum size, in bytes, of blocks you create:
blockmaxsize=50000

#How many bytes of the block should be dedicated to high-priority transactions,                                                                                                 
#included regardless of the fees they pay                                                                                                                                 
blockprioritysize=2000

#Minimum block size you want to create; block will be filled with free transactions                                                                                       
#until there are no more or the block reaches this size:                                                                                                                  
blockminsize=0

#Fee-per-kilobyte amount (in BTC) considered the same as "free"                                                                                                                    
#Be careful setting this: if you set it to zero then                                                                                                                      
#a transaction spammer can cheaply fill blocks using                                                                                                                      
#1-satoshi-fee transactions. It should be set above the real                                                                                                              
#cost to you of processing a transaction.

when I set maxconnections=10 my p2pool is not started, just stay in

Windows binary: http://u.forre.st/u/ahajjytb/p2pool_win32_9.4.zip
Source zipball: https://github.com/forrestv/p2pool/zipball/9.4
Source tarball: https://github.com/forrestv/p2pool/tarball/9.4

Changes:
* Fixed inefficient memory usage - Resident memory went from 736MB to 266MB for Diablo-D3

unfortunately p2pool wasted work do not go below 15-20% as was before hardfork

Where in my linux p2pool directory can I look to find the human-readable version number, e.g., currently, 9.4?

run_p2pool.py --version

Stale P2Pool shares are not "wasted" - they still can solve blocks and get us all a payout. They're just don't count for P2Pool credit, which affects everyone to some degree, so everything is optimal and fair as long as your efficiency is close to 100%.

Python 2.6.6

Some incompatibility with python 2.6.6? I tried it on python 2.7.3 (VM) and and no error.

It's just a warning that is actually meaningless, since it was triggered by a bug in Python. It doesn't happen for new versions of Python because the erroneous warning was removed.
