  • please bare with me as I put these threads together…

    We should get a PXC address established as they are changing over to neo tomorrow. Maybe even put together a dev fun CPU mining pool for PXC neo…



  • Are you accepting donations to these addresses for the bounty? i really want the mining to switch before these ‘super’ asics arrive and destroy FTC.

    Will happily send some FTC over to improve the bounty.

  • We have the GPU miner for AMD’s in production as we speak. So no need to grow the bounty any more.

    But, please hold your ftc and wait as we have some projects coming up which will need bounties.

    More details to come after the Neo fork…



  • Should we donate to the cuda bounty?? (Im all in NVidia GPU’s)



  • If anyone can, create a cuda clone of this bounty thread.

    no harm i suppose.



  • calem, what do you mean no harm? 😃 A CUDA miner is an absolute must!!! The Nvidia cards are much more versatile and can be used for much more applications than just mining. I am all for a cuda miner. Id be more than happy to throw the amd gpus and mine with an nvidia instead. Would pledge 2 mil UFO but wont be able to deliver then until late september… probably will be able to borrow tho



  • By “No Harm” I mean, we may as well get the CUDA bounty started now as it’s the next miner we_really need _once the AMD one is done.



  • As far as I know is the AMD miner made in OpenCL, which is running very fine on NVidia cards.



  • Woo hoo that’s great news. 🙂

    Needs new miner for farm 🙂



  • So are you saying we have a fully operational (not tweaked) CUDA miner?

    Hi all,

    The new NVIDIA Maxwell chipset uses much much less power than the AMD equivalent. Also they have ironed out problems regarding slow computation that made the previous generation chipset so poor at mining.

    In the UK you can buy a 750Ti for just over £100 that will give you around 265kHashes/s scrypt using 60 watts. It also will run much cooler so less power required for cooling also.

    I believe the high-end maxwell GPU cards are scheduled to become available in September. So long as NVIDIA don’t set too high a price for the cards I would expect a lot of miners to switch, especially where electricity is expensive.

    Regarding openCL compatibility, the CUDA SDK includes OpenCL (1.1?) support. I’ve just had a quick look at a sample of code and the C API looks similar (but not completely identical) to that implemented by AMD (small things like oclGetPlatformID rather than clGetPlatformID).

    Regarding the actual .cl code I’m still not up on enough to fully comment, but I would expect identical or at worst minor changes for a non-optimised solution (for AMD and NVIDIA). However, when it comes to writing optimised openCL code then this could diverge. For example I think I read somewhere that with AMD 79** GPUs it’s best to use the int4 vector type to ensure maximum use of GPU resources. With other GPU architectures this might not be the case, hence we could end up with, once optimisation is performed, maybe opencl code for AMD, and a different one for NVIDIA.

    Of course, first we have to get a first working version of a openCL based miner. Optimisations will come later I would guess.

    Cheers

    Dave

  • Thats right! I am an ardent nvidia advocate too because you can do lots of things with a ge force. Next stop should def be a cuda miner.



  • my 2 780ti’s are just dying to have a crack too.

    You know what I miss… Tweaking miners…

    I personally believe I hold the world record for r9 270 hashing on scrypt… 😃

    I can get max 415mhs on my asus 270x … what do you get?





  • 😃



  • Nice 🙂
