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

[windpath]

Hey Good afternoon!, I need some help as there is not a central support line. I believe my miner may not be running Getblock, I think it's running getwork. The pool shows that I'm connected and hashing, The Issue I'm having is that my miner is registering that Shares are being accepted but nothing registers under my payout address. Is there some time you have to wait, is there an error on my end, can anyone help me out, thanks!

P2Pool will accept (but not consider valid) shares below the minimum difficulty in order to better estimate your hashrate and payout.

It should give you an estimated time to share after your hash rate has been established.

Until you submit a share that meets the minimum difficulty, and the pool subsequently finds a block, you will not receive a payout.

Is there a way to minimize or increase performance on either bitcoin or p2pool

Warning: LOST CONTACT WITH BITCOIND for 1.8 minutes! Check that it isn't frozen or dead

The stats on my p2pool for bitcoin are really slow

bitcoind and p2pool are running on the same machine

thx

See gyverlb's guide for tips on how to maximize your P2Pool node's performance. It may be a little outdated, but most of the tips and pointers there still hold true today.

Please ignore the bits that suggest setting and tuning a blockmaxsize value. The blockmaxsize parameter has been deprecated in favor of the blockmaxweight parameter, which you should set to a suggested maximum of 3950000.

If you have a system with a reasonably fast CPU (one with a base clock of at least 2.4 GHz) and at least 4 GB of RAM, you may want to try out jtoomim's 1mb_segwit fork, if you aren't already, which promises better overall performance and reward fairness. Using PyPy to run 1mb_segwit is highly recommended for maximum performance.

Hi
Usually that's a RAM problem. You may want to install a 64 bit based OS so you can add more RAM or if
you have the budget you can rent a Vps.
Happy mining

[bitlock1]

Thanks,

I have plenty of ram on this system, before I try a new fork would this be a bitcoind ram issue or p2pool ram issue and what setting would I set to give the program a little more breathing room.

thanks,

Thanks for the blockmaxweight tip - I was using the old suggestions.

There isn't much you can do about P2Pool's RAM usage, as there is no user-accessible way to manage it.

You may refer to this guide if you're interested in tuning bitcoind's memory usage. Note that in Bitcoin Core 0.14.1 and later, the default dbcache value is 450, and not 300 as stated in the guide.

Strange, p2pool general failures.I had never seen this before 

[Rabinovitch]

https://en.bitcoin.it/wiki/P2Pool#Stales

Could anybody be so kind to explain in more details, what does this mean?

On P2Pool stales refer to shares which can't make it into the sharechain. Because the sharechain is 20 times faster than the Bitcoin chain many stales are common and expected. However, because the payout is PPLNS only your stale rate relative to other nodes is relevant; the absolute rate is not.

What's PPLNS got to do with it?

[bitlock1]

I have switched over to https://github.com/jtoomim/p2pool  code and things seem better, but still occasionally  see bitcoind not responding errors.

I review the bitcoind logs

Code:

receive version message: /P2Pool:17.0-4-g68f653f-dirty/: version 70002, blocks=0, us=127.0.0.1:8333, peer=41

2017-12-08 16:01:59 Warning: not banning local peer 127.0.0.1:52702!

i can increase the banscore index to 150 ? not sure if this is a good move. Any Suggestions?

bitlock1, it sounds like your machine is just too slow for bitcoind+p2pool. Please list your machine's specs, including CPU model, amount of RAM, type of disk (SSD vs HDD), and OS. It would also be helpful if you could list your node's IP address or post a screenshot of your "Bitcoind GetBlockTemplate Latency" and "Memory Usage" charts. Output while using the "--bench" command-line option is also helpful.

Usually, the "bitcoind not responding" error happens when bitcoind is responding just fine, but p2pool's queue of tasks to perform grows faster than the CPU can perform those tasks. This causes p2pool to take several minutes before p2pool processes the response from bitcoind, even though bitcoind may have responded within milliseconds. This can either be caused by running out of RAM (resulting in swapping to disk) or by a slow CPU (e.g. anything from AMD before Ryzen).

Currently, p2pool requires a fast CPU with good single-threaded performance. I wish this weren't the case, but the cost in programmer time of fixing it is about the same as buying all p2pool users a faster CPU. I've made several improvements already towards that goal, but clearly not enough.

AMD Opteron 6128 - python is running near 100% so pypy may have to be my route as this processor may be a little weak even with 8 cores
32GB Memory
Hard Drive may be a 5400rpm - this was an old server that I revived and i just grabbed a 1TB HD I had, could have probably used a SSD

I didn't realize  this was going to be so intensive ... I may have to rebuild, but will give pypy a try 1st

Bitcoind GetBlockTemplate Latency is bad - mean of 9.07 seconds
Memory Usage is about 1.9GB

However this server is also server a Dash Node and a Litecoin node and running as expected.
Latency is around .0201s on the Dash node with memory of 235MB, and about .0668s on the Litecoin node with memory of 1.26gb

I am also not sure what version of your code I am using, terrible with git, what would be the command to change from
jtoomim/p2pool
to
https://github.com/jtoomim/p2pool/tree/1mb_segwit.git
if that is the current version I should use.

--bench has been added, will supply debug.log shortly.

thanks

[jtoomim]

Yeah, an Opteron 6128 is way too slow for bitcoin p2pool. Sorry. It doesn't matter how many cores it has; it's a 2 GHz pre-Ryzen AMD CPU, and that's nowhere near fast enough. A cheap dual core Core i3 would be much better than an 8-core AMD server chip. Pypy will help, but I expect you'll still have problems even with pypy.

Dash and Litecoin should work fine. Most of the CPU load comes from dealing with transactions, and neither Dash nor Litecoin have much transaction volume.

The HDD should be fine. I wouldn't worry about upgrading that. If you are thinking of mining Ethereum, you'd need an SSD, but an HDD should be okay for Bitcoin, especially if you use -dbcache=8000 on bitcoind (you have the RAM, might as well use it).

[bitlock1]

jtoomim,

I setup pypy and it is running about the same - so will try this for a few days and see if my latency drops.

It looks like I was running the forest master branch after researching git somewhat.

Are you still suggesting to run your 1mb_segwit branch?

thanks

Hello,

I've recently switched from the main p2pool to jtoomim's fork, due to issues with cpu load. P2Pool works, and I can mine, but over time my node start creating huge amounts of orphans. An analysis of the problem showed that the issue was the cpu load. It's nearly always at 100%. I also saw the same messages that other people on this forum had, namely that the connection with bitcoind was lost. It is indeed so that this starts to happen when the cpu utilization is at 100% for a very long time. I must say that this became only quite recently an issue for me. I've been using p2pool for over a year now, but it is only the last couple of weeks that the cpu utilization became an issue. At first I used just python to run p2pool, and this was sufficient. Recently I switched to pypy as an attempt to alleviated the problem with the cpu load. This diminished the cpu load slightly, however not sufficiently, and my node still gets a lot of orphan shares (the stale rate is enormous: between 30 and 50%). So at that point I decided to switch to jtoomim's fork because of the optimalizations.

However I experience some problems. Well actually I haven't been able to mine at all with jtoomim's fork. Somehow my miners don't mine. I know the miners work and so does the setup because I can mine 'perfectly' on the main P2pool. But when using jtoomim's fork all the work of my miners get rejected. I also see the lights flashing on the usb miners, so they are active.

Cgminer gives me the following:

It keeps on doing that. I see that new work is send to the miners. Also the rest of the output makes me believe that the P2Pool node is running as it should.

The cgminer command I use to run cgminer and connect to p2pool is the following:
screen -d -m -S cgminer ~/git/vthoang/cgminer/cgminer -o stratum+tcp://127.0.0.1:9332 -u xxxxxxxxxxxxxxxxxxxxxxxxxxxx -p xxxxxxxxxxxxx --suggest-diff 32 --gekko-compac-freq 150 --gekko-2pac-freq 200

Can someone explain to me what i'm doing wrong?

Thank you

Extra info:
My setup is the following:
* Processor: i3 M350 @2.77Ghz (so it is not a powerful processor)
* RAM: 8GB
* OS: ubuntu server 16.04 LTS
* mining software: cgminer 4.10
* miners: a couple of gekkoscience compac and gekkoscience 2Pac

After mining for about 8 hours pypy is doing much better, was watching the cpu utilization and it never hit 100% like it did with python so I will watch this for awhile and it looks like the miners are generating shares

http://97.77.64.18:9332/static/index.html
The graphs page show a great decrease in latency  
The stats do show we create/solved a few solutions.

I still need to make sure I am using the correct branch.

I am seeing some of the same results as Cryptonomist....but assume my miners were too slow and the transaction was already complete.

Are you still suggesting to run your 1mb_segwit branch?

Yes. http://github.com/jtoomim/p2pool master is currently just an old snapshot of http://github.com/p2pool/p2pool master. All of my new code is in 1mb_segwit. It looks like that's what you're running now, otherwise you wouldn't be getting the --bench output.

bitlock1, it looks like your node is sorta working now, but not very well. Your mining efficiency is only 73%. This is probably because of the slow CPU. When you're running p2pool with a slow CPU, it can take several seconds for your machine to download a new share from a peer, deserialize it, build a new share template, and send that share template to miners. In your case, it took 4.2 seconds to do the deserialization step, and up to 1.3 seconds to build a new share template. This means that your miners are hashing on an old share for at least 5.5 seconds out of every 30 seconds on average. That alone will reduce your expected revenue by about 18.3%. (There are also a few processing steps that aren't accounted for in my --bench output, which may be why you're seeing 27% in practice rather than 18.3%.)

However I experience some problems. Well actually I haven't been able to mine at all with jtoomim's fork. Somehow my miners don't mine.

Can you try mining on a different node on jtoomimnet to test to see if the problem is with your node or with your miners? You can use ml.toom.im:9332. If your node has publicly open ports, it might also be helpful if you PM me your IP address so I can take a look.

Cryptonomist, your CPU is faster than bitlock1's, and is probably fast enough to run jtoomimnet p2pool with pypy and with an acceptable (but not excellent) DOA+orphan rate, though of course faster would be better.

Edit: based on PMs, it looks like Cryptonomist's setup is working okay. jtoomimnet will often choose higher pseudoshare difficulty, especially on startup, and Cryptonomist is using USB miners with a very low hashrate (~80 GH/s), so he's only finding one stratum share (p2pool pseudoshare) every 15 minutes or so. But it's working.

I have a test node up mining Bitcoin Cash (using Bitcoin ABC) at http://woff.toom.im:9338/. I don't know if it can successfully mine blocks yet though.

I have a test node up mining Bitcoin Cash (using Bitcoin ABC) at http://woff.toom.im:9338/. I don't know if it can successfully mine blocks yet though.

Give me the source code, please, I will connect 2-3 nodes.
I have many miners who require a BCH node

[Minerdude8]

The closest node from me shows a very high latency, so I would like to set up a private noed for my 9 Antminer L3+s. I read here that the requirement is not that huge for Litecoin. Problem is that my internet speed is pretty low and I cannot improve it from 5mbit/1mbit(upload), is that a problem?

I got a Intel NUC NUC6CAYS Intel Celeron J3455 1.5 GHz, 2GB RAM, Windows 10. Can this run a node?
