[Dev] Feathercoin - P2Pool-Neoscrypt - Now Available

Wellenreiter

@Ghostlander,
The pools can connect now, but no share information is exchanged, so no common cloud is formed.
I think it is due to the different handling of endianess, that is also influencing the communication between the pool nodes.
I see messages like gent_x doesn’t match local gent_x (something like that )

my Local rate and Global pool rate always wrong , I don’t know what is that.

But my GPMniner mine PXC normal. I can recevice PXC from p2pool.

ghostlander

Wellenreiter, your P2Pool base code was forked in Dec-2013. It’s getting old.

There seems to be three seperate p2pool pools from what I see from nodes: Wellenreiters, ghostlander’s and a 3rd which I seem to be joining with my node.

Wellenreiter

That is not very likely.

In the list of bootstrap addresses in the p2pool neworks file are only Ghostlanders two nodes and the two nodes using my flavour of p2pool, so your pool node will start to connect to one of these normally.

Suggestion: delete the file ./data/phoenixcoin/addrs and then start your pool

You can get a list of active peers with the link http://

:10554/peer_addresses

If the above doesn’t work, add the option -n with the ip address:port of one of the nodes in the list

Re-did p2pool again today (did that about 15 times yesterday), and it downloaded all the shares…not sure what was going on. Didn’t do anything different.

Today,I had test p2pool and cgminer again. I still find some problem.

GPU miner version : vehre’s cgminer 3.7.1

from https://github.com/vehre/neo-gpuminer

P2Pool version : ghostlander’s 13.4-54

from https://github.com/ghostlander/p2pool-neoscrypt

AMD Card 7850 and AMD 13.12 Catalyst + SDK 2.9

My p2pool is http://pool.ftc-c.com:10554/static/

Pool rate: 662kH/s

I think pool rate is right. :)

Issue #1:

Cgminer works abnormally and local rate always 0H/s .

If I use " --fix-protocol -o http:// " ,cgminer will not work. It say JSON error.

If I use “-o stratum+tcp” , cgminer can run , but it work abnormally, local rate= 0H/s .

my pool rate is right,it is 662K/s. local rate is 0, I think gpuminer or p2pool work abnormal.

wellenreiter01’s p2pool-neoscrypt still have some problem too. pool rate and local rate is very low.

I hope you git your codes from github, build a new pool , test again, I think you can find some error. I guess you may be miss something. :)

Wellenreiter, my gpu-miner can mine PXC norml in your p2pool, local rate about 10K/s.

I thinl pool20.neoscrypt.de is right. so please check your https://github.com/wellenreiter01/p2pool-neoscrypt/

I guess you may be miss something.

ghostlander

If I use " --fix-protocol -o http:// " ,cgminer will not work. It say JSON error.

I have corrected this.

Getwork Fixed, Midstate Removed

After I change SANE_TARGET_RANGE = (2**256 - 1 >> 30, 2**256 - 1 >> 12) to SANE_TARGET_RANGE = (2**256//1000000000 - 1, 2**256//1000 - 1) , cgminer can work normal ,but pool have not hashrate , Local: 0H/s .

I will try Wellenreiter’s new version on git https://github.com/ghostlander/p2pool-neoscrypt

lizhi

I have corrected this.

Getwork Fixed, Midstate Removed

I make your cgminer-neoscrypt , I have a error. can not compile success.

**P2Pool version : ghostlander’s 13.4-54 **https://github.com/ghostlander/p2pool-neoscrypt

**GPU miner version : vehre’s cgminer 3.7.1 , **AMD Card 7850

Test Failure

If I use “SANE_TARGET_RANGE = (2**256 - 1 >> 30, 2**256 - 1 >> 12)” in p2pool/bitcoin/networks/phoenixcoin.py , p2pool always display " Accepted d94ffdc3 Diff 145/-2147483648 GPU 1" , This is a abnormally informtion.

local rate is 0, I think gpuminer or p2pool work abnormal.

If I use “SANE_TARGET_RANGE = (2**256//1000000000 - 1, 2**256//1000 - 1)” in p2pool/bitcoin/networks/phoenixcoin.py , p2pool display " Accepted 329bea3e Diff 3/1 GPU 1 ", This is a right .

But Local rate is 0 still , p2pool always display " Worker PfF9PKBjkmz7gFAkA7h6ajY5AHc9B1mijW submitted share with hash > target: " .

p2pool can not work ,mine pxc failure.

ghostlander

Your MinGW doesn’t declare sleep() and pth descriptors. My one does. See the last patch for Windows 64-bit and revert those changes you need.

**Wellenreiter’s p2pversion : 13.4-34-g1eb6d7b-dirty **https://github.com/wellenreiter01/p2pool-neoscrypt/

CAN WORK WITH A ISSUE

If I use “SANE_TARGET_RANGE = (2**256 - 1 >> 30, 2**256 - 1 >> 12)” in p2pool/bitcoin/networks.py , can not work too .

If I use “SANE_TARGET_RANGE = (2**256//1000000000 - 1, 2**256//1000 - 1)” in p2pool/bitcoin/networks.py , p2pool can work, cgminer can work normal.

But have a problem only , p2pool display "local rate is very low ". cgminer display 20K/s , but pool display about 400H/s only. :-[

Wellenreiter

Strange thing is, that cpuminer works fine for me’ while gpu miner get’s very low hashrates on the pool only

I wil investigate further.

Further examination

I find my cpu miner work normal ,their hashrate is about 3K/s , correct .

Only gpu miner’s hashrate is very low, about 400H/s. When they work at the same time, cpu miner work normal, but gpu miner can not work.

I think your gpu miner too on pool.ftc-c.com:10554

When they work at the same time, cpu miner work normal, but gpu miner can not work.

cgminer 3.7.1 Look normal

Wellenreiter

Gpuminer 3.7.0 is working fine for me on p2pool.neosrypt.de:10554
With 3.7.1 low hashrates of ~400 hash/sec is seen by the pool.

my miner 3.7.4exp is Ph5Cy7cGhF3qW14cD6w8DJcSVPrLmX4Goa ,it is working on your pool20.neoscrypt.de

It look normal , have 20K/s hashrate.

how to fix your p2pool ?

Wellenreiter

mining at ~ 35 khash on p2pool.neoscrypt.de with gpumminer 3.7.5 , what is comparable to the hashrates the miner reports :)

I pulled the latest p2pool code and currently test it on a private node.

I will push that code as soon as the tests are finnished.

Wellenreiter

A new version of the p2pool is available on Github.

Changes:

import of latest master code with significant code changes
adaption to Ghostlanders pools, so the pools now can fully connect to each other and build a common pool.
tested with cpuminer and the latest version of gpuminer.
longpoll and stratum are supported
