      If any of you wants to help with either Python code for P2Pool or PHP code for MPOS or OpenCL kernel for [cg,sg,bfg]miner, I have no problem of sharing the reference code with you. I’m going to finish CPUminer first.

      P.S. My notebook has blown up yesterday due to summer heat. Shouldn’t have purchased Alienware, lesson learnt.

        Probably I’ll be avaliable for MPOS in one week from now. After that I can jump into p2pool if no one else is interested :)

          Beta 2 is ready. All reference code is in place. 64-bit assembly code is also there, though it works well for the Intel CPUs only. The AMD CPUs are better with the reference code, though I have tested the K8 and K10 generations only. Working on the environment now.

          Thanks for updating us about the process!

            Could try to adapt and setup p2pool, but not sure how to test it without a working miner.
            If the block prefixes don’t change, not much to do here, I think.

            Eventually can help with cgminer, but I’m not an experienced c/c++ programmer. So if you could share the code I can give it a try at least.

              Is it very difficult to have merged mining of all Neoscrypt coins (similar to Blake 256 system)?

              Just a tought…

                Same here!

                I can offer my (very) limited c++ knowledge but you’ll have to explain me what to do ;)

                  I can at least take a look at the python stuff (not promising that I can help since I don’t know what level of programming is required before I’ve looked at the code) and see if I can help out. Just finished version 1.1 of our chargeback system at work written in python so I need a new project to set my teeth in! ;)

                    I’ve completed CPUminer nearly. The only issue left is endian conversion: all Bitcoin derivatives are little endian inside, so NeoScrypt is also little endian completely. SHA-256d and Scrypt are big endian ones due to SHA-256 being employed by both. CPUminer is also big endian inside.

                    The P2Pool module seems to be a simple wrapper over the reference code, so this is an easy part.

                      Great news thanks for all your hard work on this. I think some tips are in order!

                        CPUminer works now in both native (NeoScrypt) and legacy (Scrypt) modes. Not parallelised much yet, so the performance is the same to the internal wallet miner. NeoScrypt and Scrypt should deliver very comparable CPU performance, maybe NeoScrypt a little bit better.

                          That’s great glad to hear the initial results are showing a performance improvement with neoscrypt.

                            I’ll start on the p2pool modifications today.

                              I’d relly like to knwo how you “make” a miner… or a p2pool.

                              Respect guys! You’re doing all this in two? three people?

                              You rock!

                                The glory goes to Bushstar and Ghostlander.

                                I don’t do veery much here, as my programming experience in the crypto area is not that much.

                                I can modify exsiting code a bit, that’s all. ;)

                                    I like my sgminer, but I think Iam not smart enough to modify it :/

                                      Also, the thought crossed my mind, what we could do for those mining with Nvidia GPUs?

                                      Anybody able to modify cudaminer?

                                        Having support for all the camps from the off will make for a stronger launch.

                                        Like what I do: 6uuy6isbrW1SBF191Bzgui1gWxPdNKx2PB

                                          I’m hoping we can deal with cudaminer (or sponsor/commission the guys who wrote it to implement neoscrypt?) Again I would be happy to chip in as I am one of the many who would benefit from nvidia support!

                                            I’m curios as to how Neo would work out on nVidia… x11 seems to have an advantage with em, could this be the case here?
