Changing the hashing algorithm

Wellenreiter

Based on Ghostlanders phoneixcoin p2pool and the scrypt based p2pool I mananged to get a neoscrypt p2pool working.

it can be found here:

https://github.com/wellenreiter01/p2pool-neoscrypt

and cloned with

git clone https://github.com/wellenreiter01/p2pool-neoscrypt.git

Please use and test it.

Add your test results, comments, remarks here:

https://forum.feathercoin.com/index.php?/topic/7531-p2pool-neoscrypt-available/

From that repo and the recent commits it looks like your still using the ltc_scrypt module? and the one in the repo is the normal scrypt one?

Thank you so much for your help ahmed.

I’ve been caught up with work but I’ll be in contact.

Where is our feathercoin-testnet p2pool ?

Can’t sync,my feathercoin-testnet can not connect network.

I’m not sure. I’ll bring Pete’s attention this way when he has a chance.

edit

pm’d you.

I think someone should add NeoScrypt to this wikipedia page:

https://en.wikipedia.org/wiki/Scrypt

The section with implementations would probably do well with a link to the github.

If anyone can improve the kernel file (neoscrypt.cl), then I will soon be completed .

What sort of thing is wrong with neoscript.cl Lizhi?

I need a openCL kernel for neoscrypt. main code is __kernel void search()

MrWyrm

I enjoyed that. Solo mining on the phoenix test net, PhenomII X4 940, 4 threads, listed at the bottom as 9202 hashes per second.

I’ve been looking for some information that might point us in the right direction. I skimmed openCL , but don’t know what is involved in creating a kernel.

I found this Github for scrypt that might show how it is done.

Training in openCL

Yes that does look a bit “complex”

all seems to be very quiet now, are we waiting for someone to develop the GPU miner now?

Cheers

When the forum get’s the quietest, the harder the team is working behind the scenes…

I have a team in Russia, a cryptographer in Germany, budding young talent in Egypt, and an ex nasa guy in the USA, just to name a few, who are potential candidates for the bounty.

I had put my project .Please downland http://www.ftc-c.com/pack/cgminer-master.tar.gz , I had finished some code for GPU Miner, Now I think needs to write neoscrypt.CL

You can compily it:

cd /D/FTC/neoscrypt/max-cgminer-master
autoreconf -fvi
export LIBCURL_CFLAGS=-I/usr/local/curl/include
export LIBCURL_LIBS=-L/usr/local/curl/lib
CFLAGS="-O2 -msse2" ./configure --enable-scrypt --enable-keccak  --enable-neoscrypt
make

Run cgminer.exe

setx DISPLAY 0
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

cgminer --neoscrypt --worksize 128 --thread-concurrency 200  -o http://pool.ftc-c.com:19328 -u lizhi -p 12345

great work lizhi. Ive been reading up on opencl but its early stages. but it may be while before I am able to create something.

Wellenreiter

Lizhi,

what is your pool? is it a p2pool and is it working?

Or is it just accepting hashes from the miners, but not forwarding to feathercoind?

My neoscrypt-p2pool is http://pool.ftc-c.com:19328/static/

I used your p2pool codes. I find it is not work.

Add sgminer 4.2.2 . I will push as soon.

kernel file path is kernel\neoscrypt.cl

sgminer --algorithm neoscrypt --worksize 128 --thread-concurrency 200 -I 8 -o stratum+tcp://coinotron.com:3337 -u cqtenq.1 -p 110

cd /D/FTC/neoscrypt/sgminer-master
autoreconf -i
export LIBCURL_CFLAGS=-I/usr/local/curl/include
export LIBCURL_LIBS=-L/usr/local/curl/lib
CFLAGS="-O2 -Wall -march=native" ./configure --enable-neoscrypt
    ## May be edit Makefile: LIBS = -lpdcurses -lpthread  -lcurl -lcurldll
make
