      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.

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

                  Like what I do: 6uuy6isbrW1SBF191Bzgui1gWxPdNKx2PB

                    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

                    Training in openCL

                    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

                              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

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