Changing the hashing algorithm

mnstrcck

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.

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

I pushed my code to git repositories :

https://github.com/cqtenq/sgminer

I download vehre’opencl , cgminer.exe can start,but not share.

cgminer --neoscrypt --worksize 128 --thread-concurrency 200 -I 8 -o http://pool.ftc-c.com:19328 -u TRsuTqxAMKZNvC7JzGNgvM49rkQNcxqjhi -p x

MrWyrm

Have you tried with --no-stratum?

lizhi

The screen shot is wrong. cgminer.exe can not run :-[ . window and linux there may be different.

lizhi

Now , cgminer can start, but can not mine. My AMD Driver is SDK 2.9.

cgminer.exe --neoscrypt --worksize 256,256 --thread-concurrency 1600,1280 -I 8,8 -g 1 -o http://pool.ftc-c.com:19328 -u TRsuTqxAMKZNvC7JzGNgvM49rkQNcxqjhi -p x
