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

[maqifrnswa]

Aside from the fact p2pool's 90 day "luck" is at 88.5%, and 30 day "luck" is at 57.1%.  Aside from that, yes, it's great.

is there anywhere a graph about the luck of p2pool from the last 90 days?
TIA

http://p2pool.info/luck/

7 day luck 136%
30 day luck 100%
90 day luck 96.4%

@Aseras: I'm really interested in hearing how the avalons work on p2pool, besides jgarzik i don't know of anyone that has one to even try yet. Congrats and good luck!

[Aseras]

I think I got it working, it was a royal PITA.

lets see if p2pool hashrate doubles in the next hour or so.

/you should see the output of p2pool it's scrolling like hell. 20 lines a second!
//is there some way to turn off the new work for worker spam?

Oh yeah, that's a pretty sight...

Having trouble keeping it stable. P2pool keeps crashing. Will only run for an hour or so before it blows up.

It probably can't keep up with the massive hashrate. Might wanna get rid of the --fix-protocol flag.

Have to use it. Otherwise avalon won't run. it doesn't like double byte stratum. Needs to be fixed. It's a known issue.

What we need to do is get Forrest an Avalon to tinker with

It's not speed the CPU is fine. It's on a ssd 3930k system. It's not even touching the box. It's seems more like a resource contention problem with memory. Python is running 700-800 mb. Box has 32 gb of ram. usually when it crashes it blows up python and i see tons of weird errors and then scrolls bitcoind lost connection. Restarting p2pool.py fixes it.

You guys are invited, we love you. How about ssh to a unit? You get it happy, you keep the bitcoin it mines while you work?

Alas you can't change the software on the unit, it takes uploaded firmware, so the only thing you can do is change the settings being passed to cgminer. While I'd be happy to tell your avalons to mine for me, I can't really improve cgminer to work better on them. Like I said, we weren't invited to the party.

As an aside, use the latest p2pool from git which should at least work with stratum with them and improve their reliability. In short, though, you lose on average .7 seconds of work per longpoll with Avalons. That's a fair percentage with average 10s longpoll equivalents.

I'm using the latest git pull.

What do you need?  the avalon modified cgminer source code? Need to light a fire under Yifu, zhang and xiangfu to get a real working copy. https://github.com/BitSyncom/cgminer.git

You can modify the software/firmware. I've been doing it all day. I pulled down the latest firmware and hacked the crap out of it and got rid of things I didn't want. Freed up some room. Enough to tinker and add my own scripts and such.

And p2pool crashed again... Keeps imploding and dropping connection to bitcoind. Gonna have to send Forrest some logs.

The avalons are mining fine, better since I went to U/2000+1 without diff they hammer the piss out of the server. Still 10-15% DOA, but better than 25% I started with.

The BFLs will work fine on p2pool - get one of them ... whenever they are available

Meanwhile ... now what did I say to GitSyncom about "proper" Avalon support ... they sure aren't providing anything like that ...

[Aseras]

I wonder if I ran one of the get work to stratum proxies if it would work on p2pool?

Well I don't know why you're taking this on yourself... I appreciate the gesture but it's not remotely trivial. Let me explain why it's now not that simple. As the avalon code was developed in secret outside of cgminer development, they worked on a codebase that is now redundant, hacking into it in a way where the only driver that works is for avalon. Cgminer's usb code and queueing has completely changed since then. To bring the avalon code into line would require large chunks of code to be rewritten to suit these changes. This is the danger of writing code out of the main tree. Now porting it to the new driver and queueing model and requires quite a bit of time effort and testing, and needs someone to support it (or not if it's abandoned). This is not in the scope of "lend me access to your mining hardware for a few hours over ssh".   I suspect Xiangfu will eventually be forced to keep his code in sync with the main cgminer git tree.

Yes I'm bitter about the whole Avalon experience, seeing them mine 10s of thousands of dollars worth of bitcoin each day with software mostly written by us, without them engaging us at all (except to get into a bunfight with Kano) or us earning a cent for our part, but it's not your fault.

Well it's better than anything anyone else has right now, save asicminer. And he's probably using the same thing just in bigger cards I bet.

I've had enough fun for the day. I gotta get to bed. I have to fly to Italy and go play with a lidar unit on a NATO ship. Fun fun..  Glad I got my units in before I left.

Well someone's gotta do it. Ill see what I can do. I can code and tinker. I just don't like to much. I'm gonna be gone a fair bit of April. So if you want to screw with my units you can but you may have to call one of my techs to hard reset them if you bork one and can't reset it remotely.

It's an offer if you are interested in doing it right

Ps I've probably given you 50 coins by now, over the past couple years. Keep up the good work.

[PatMan]

Oh lordy. 

I wonder how many other people from this pool have ordered Avalons thinking they're gonna work wonders on p2pool?

Maybe p2pool will be the last bastion for gpu mining?......

[aspirez]

Hi i have question,
can i run public pool, using p2pool?
Is there some limit of the max connections?

[Aseras]

Well I can't get it stable. I tried it under Ubuntu, under python, under windows binaries and python. Still crashes once python/p2pool eats ~1.2gb of ram it blows up and takes down bitcoind. I tried the stratum proxy, old getwork mining proxies,you name it. Nothing will run more than a few hours.

I may try baking my own firmware with some alternative builds, but for now its not working. I can mine on btcguild or slush or eloipool solo and not have any problems.

I'm going to offer a starting bounty of 10BTC for anyone who gets the avalon working properly and stable* on p2pool.

*Ill define properly as a reasonable hashrate and DOA rate ( ~25% on fix-protocol ) and stable as 1 week uptime without p2pool or bitcoind crashing. The avalon itself is buggy and restarts sometimes.

Why is python/p2pool using so much memory?  I thought the memory leaks were fixed?

What's different about an Avalon from a normal GPU?  The obvious thing to comes to mind is the massive increase in hash rate.  Does p2pool properly scale to keep the difficulty to the miner at a reasonable pace?  Did you try manually forcing the difficulty higher? 

According to https://en.bitcoin.it/wiki/P2Pool, I think you just add /xxxxx to your username to increase the share difficulty.  At 60gh, to get 5 shares an hour, I think it's saying use /10000.  But as many times as I've looked at this page, and the link it refers to https://bitcointalk.org/index.php?topic=18313.msg816322#msg816322, I still don't understand what it's trying to say.

Sounds like the problem is all in the p2pool end anyway? Can you tell if it's actually successfully connecting directly stratum because that would be essential to avoid p2pool sending a lot and higher diffs would be essential to avoid p2pool receiving a lot.
