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

[Syke]

It's not pretty but it's there in the output:

>3025MH/s Shares: 468 (39 orphan, 18 dead) Peers: 14 (4 incoming)

[cheat_2_win]

Haven't received a payout for two days. Is this just another block drought or is something wrong with my setup?
I'm seeing 156GH/s so I'm not on the split chain.

We found two blocks on the 31st, two blocks on the 1st, and two blocks today. Payouts should be steady.

After that, it has been kind of dry spell  .

[Syke]

Just my luck. I double my hashing on p2pool and then dry spell. Argh!

Seriously, a day or two without a block is no big deal. p2pool is running great!

[gmaxwell]

I have consistently higher stales than the pool. Today I mined my HD8650 for 8 hours non-overclocked (so at ~210Mhz instead of ~250Mhz) and that did not improve it any. On average p2pool reports ~16%+-16 while the pool is usually about 8% (today it even reported 23%+-23% !)

Is there anything I can do about this?

What reject rate does your rpc miner show?  Are you running NTP (is your clock correct)?

The big -/+ means you don't really have much data for the estimate.  Those ranges mean that in fact your true stale rate might actually be pretty low.

Because you're a bit behind when you start its usually to get a couple stales right away that makes the number start out poor but then it improves with time.  It's not unusual for me to see stales at 20% shortly after startup but by efficiency is usually at 100% by the next morning or so.  (converges a bit faster if you have more hash power though)

Watching

Regarding some questions I saw here:

cgminer > guiminer, even if guiminer is already set up, just for the automated overclocking options and temperature monitoring alone

Bitcoin-qt WILL crash if your wallet.dat is encrypted. Use bitcoind instead, or don't encrypt your wallet.dat (if you're using Windows, you can encrypt the wallet file manually by right-clicking on wallet.dat, going to properties, and checking encrypt there. Supposedly this will protect your wallet.dat contents from being stolen, but don't trust me on that)

P2Pool will not connect AT ALL unless your bitcoind is fully loaded AND has the whole blockchain downloaded.

[wachtwoord]

What reject rate does your rpc miner show?

Miner reports: 0.4%  stales (1 in 250)

  Are you running NTP (is your clock correct)?

What is NTP? My system clock is correct if that is what you mean.

The big -/+ means you don't really have much data for the estimate.  Those ranges mean that in fact your true stale rate might actually be pretty low.

Would seem obvious but then it should be 0-44%. 20±20% normally means that it is most likely to be 20% but this estimate can be off 20%. I find this pretty odd when the p2pool reports 0 orphans and 0 dead.  (why does it report 20% stales? Based on what measurement?

To summarize: I have no clue what it is supposed to be reporting.

[m3ta]

20±20% normally means

What this means is that you should upgrade, because, for a while now, P2Pool's log is like this:

Code:

Pool stales: 9% Own: ~0% (0-78%) Own efficiency: ~110% (24-110%)

The "±" is not used for some time, so you have an oldish version and it's really not worth it to make any assessments based on a not updated version.

[ChanceCoats123]

I finally got my posting rights for the regular forums so I could ask these questions:

1. I'm currently using the latest cgminer and the latest p2pool with bitcoind for mining. As of late I've been having extremely low shares. I have a single 5870 mining at 950/300 and I get a reported 385mhash average. However p2pool.exe is reporting only 200 mhash. I have a feeling that is why my shares are low...

2. Is anyone successfully using poclbm? I get 410mhash at the same settings but all of my shares are being rejected. I know there was a github link for getting poclbm to work, but I can no longer find it. Any help is appreciated.

Thanks in advance.

2.5 and 11.12 drivers. I need to change the drivers. I should probably check again for p2pool updates too. Which drivers do you recommend, by the way?

Edit: I looked around and the github archives of p2pool have 0.8.1 on top and then 0.8.2 on bottom. I hadn't noticed it until I looked at the release dates.

Still doesn't seem to fix any of my issues though. P2pool used to actually display close to my actual hash rates in the Recent section, but it's reporting 185mhash/sec which is not even close. I'm also barely getting work. I know the difficulty is higher, but I used to average 20-30 shares per day and I've had 8 in the last 24 hours.

I'm looking into drivers now for cgminer performance issues...

[Rassah]

Using newest p2pool and newest cgminer now. Noticed the change with cgminer reporting a lot more shares as being ACCEPTED, which I guess it to check to make sure it's working.
One quirk with p2pool though: the most hashing power I can get out of my cards is 530Mh/s. That's what cgminer is reporting as my average. P2Pool, however, is reporting
Recent:  0.66% >1092MH/s
Why is that? And is this a bug that may be distorting the total p2pool hashing power, if a lot of people are experiencing (reporting) it?

[ThiagoCMC]

It needs 2 hours to calculate...

I just add 1.3GHash to P2Pool!

If this works nicely, I'll add more 10 next week... 

Plus a quick guide for the community members!  ^^

Cheers!
Thiago

[ThiagoCMC]

Well... What a hell... More 1.3GHash...   

[Syke]

Unlucky block, someone's probably trying to hop. More power to them, that's more shares for me!

[Fiyasko]

Hey guys! Im really intrested in running in the P2Pool, PROPERLY....
Me running in P2Pool...Please tell me something Wrong is going on here...

The P2Pool window (wich i for somereason cannot Copy out of) consistently states
"Recent : 0.00% >0H/s Shares: 0 (0 orphan, 0 dead) Peers :10"
Making me think that either there is a information pulling error
Or that my work isnt being counted.
Or that my work isnt being counted as "my speed"

also, Whenever p2pool goes: New work for worker!"
Cgminer (at the same time) goes: "LONGPOLL requested work restart, waiting on fresh work"

Where as with DfeepBit i get:

I hear that there is a noteable differance in share structure difficulty for p2pool, But surely SOMETHING, is running incorrectly.
The amount of work im getting from P2Pool is apparently so low that im wasting hashing power, That just cant be right.

I also noticed that when using my comp that has an AVprog, P2Pool runs like Garbage (Most definitly due to the AV prog scanning P2Pools traffic). Turning off the AVprog allows P2Pool to run and mine, But it runs like crap...

I cant help but Assume that i Will Not be paied for the 18 shares that i submitted, Because i forgot Where to put my bitcoin address. Perhaps thats why everything is messing up?

[ThiagoCMC]

@JackRabiit

I'm writing a Quick Guide for P2Pool... This is the kind of pool that Bitcoin network deserves.

I would like to see it with 1THash in 3 months! 

[Red Emerald]

If you don't specify a bitcoin address, bitcoind automatically generates one. I think it even automatically gets labeled p2pool.

[Vanderbleek]

JackRabiit, the longpoll statements you are seeing are correct. It SHOULD be showing up every time p2pool says new work.

[ChanceCoats123]

2.5 and 11.12 drivers. I need to change the drivers. I should probably check again for p2pool updates too. Which drivers do you recommend, by the way?

I use 11.12 and 2.5 sdk. Also it's difficult to roll back the sdk if you've installed a newer version, are you sure you are on 2.5? And, if you build the binaries on cgminer and then change sdk but do not delete and rebuild the binaries, you will still be getting the old hash rate.

In other words, say you have 2.6 installed and run cgminer for the first time from a fresh download, then you change sdk and don't delete the .bin file in the cgminer folder, you will still be running 2.6. I'm not sure of the technical reasons for this, but it works for me.

It's definitely the 2.5 SDK. I uninstalled all previous OpenCL and ATI drivers before I got it installed then went to 11.12.

As for the speed update, I will wait the two hours to see if that works. I'm still hardly getting shares though. It's just bothering me because it seems I've had a huge drop off in shares lately, but my speeds have been consistent for almost a month now. I've also not seen a paycheck in a while (which I know is to be expected), but it's been long enough to make me unhappy...
