        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:

          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?

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

                    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()

                              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.

                                https://github.com/litecoin-extras/efficient-scrypt-kernel

                                http://handsonopencl.github.io/

                                Yes that does look a bit “complex”

                                https://github.com/eXtremal-ik7/xpmminer/blob/master/src/OpenCL/kernel.cl

                                  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?

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