Hello,

I have been working over the past weeks on version of ccminer (cuda) supporting neoscrypt algo for and I have decided to release it as a crowdfunded project.

This means that it will be publicly available and opensource once the donation reach a certain amount.

Right now this amount has been fixed at 5btc,however I might release it before.
Now, if there isn’t enough people who donates, the miner will be only given to those who have pledged after the pledge period has ended.

Donation will have to be made to that btc address: 18UZRrybgjmR4M53Aca4Q8YBguqErZ5qaP

(more details on the original post: [https://bitcointalk.org/index.php?topic=916336.0)][0]

As of today, the miner gives these hashrates:

gtx980: 495kh/s

gtx780ti: 217kh/s

gtx750ti: 131kh/s

(using the opencl/sgminer miner would give for the 750ti around 40kh/s so it is already at least 3x time faster).

Thanks in advance for your contributions.

For those who don’t know me (I am mostly active on bitcointalk forum under the same username),

I have been actively working on gpu miners for some time now,

and most recently I developped:

* vtc (lyra2re) gpu miners for both nvidia and amd cards (hired by the vtc team)

* coinshield (skein-keccak 1024) gpu miner for both nvidia and amd cards (hired by coinshield team)

* cryptonite m7 miner for nvidia

Hello here a repost from the pledge I am currently running on bitcointalk regarding faster neoscrypt kernel:
the donation target is 2.5btc and already 2.06btc has been collected so we are almost there. Please don’t hesitate to donate and support our development effort.

Hello,

I am about to release a new version of ccminer supporting neoscrypt, it is around 25% faster than the sp/pallas version compiled with cuda 6.5
and around 100% faster when compiled with cuda 7.5

This is a co-joint effort between myself and Nicehash which will contribute to the pledge as well

This means that it will be publicly available once the donation reach an amount of 2.5btc.

Donation will have to be made exclusively to that btc address: 16UoC4DmTz2pvhFvcfTQrzkPTrXkWijzXw
(careful it is a new address, not the old one, one should already consider that 0.1btc has been donated)

The goad for this pledge is of 2.5btc (included NiceHash contribution).
The pledge start now (obviously) and should end the January the 24th (ie 2weeks and half).

If the pledge is successful both windows and linux version (the source) of ccminer will become available.

If those 2.5btc target is met, then the miners will be released through NiceHash

Current speed of the miner:

The hashrate given in the image is for ccminer compiled with cuda 6.5, I am also planning to retune the miner with cuda 7.5
At the moment the hashrate for the 750ti is mostly unchanged while the 980’s lose around 40kh/s.

Thanks in advance for your participation. :smiley:

He better work on it, because with current state of donation, no way I open source my software.

No bragging. If anyone donates enough crypto for me to buy a GTX 980, I write a fast OpenCL kernel and release it for free + future updates if any.

Well it is free but you need people to donate a card, so that’s not really free :) No I guess you understand the reason for a pledge…

Regarding Nvidia cards, sure I support their products. They have nice cards some are clearly overpriced but not all. The 750ti was pretty cheap and pretty good for mining (and the forthcoming gtx960 shouldn’t be too expensive with performance probably better than the 750ti).

Regarding opencl. Wolf0 who developped neoscrypt kernel for sgminer5 claims he has a kernel (private) doing 600kh/s on 290x may-be you could try to reach that speed with yours and release it for free, I guess you already have the material (Wolf0 won’t be happy if he reads me ;) )

I would happily put some cash forward for an improved NVidia NeoScrypt miner. I can’t cover a whole card but I’ll put in £40 of crypto.

or you could pledge for my miner based on ccminer (which should get released in about 2 weeks)

I saw that you are running 3 750ti at a total hashrate of 120kh/s

with ccminer you’ll get about 130kh/s per 750ti ie: 390kh/s instead of 120kh/s

(and I am still working on it)

The reference OpenCL kernel isn’t optimised for any particular architecture therefore you get what you get. There is no problem to optimise it for NVIDIA further meeting or exceeding your results, but I have no access to the new Maxwell based cards and not willing to buy any of these with my cash. NVIDIA doesn’t support open source software, so why should open source developers support NVIDIA?

Frankly speaking, I don’t think you can sell your miner for 5 BTC. Not sure you can get even half the price considering the current decline in crypto. Maybe you can try other ways to make a profit out of your miner.

First it is always nice bragging that you can do this and that but if you don’t do it. It is a bit pointless… :)

Also, nobody ever released a decent opencl kernel for nvidia cards and scrypt (for example) and it was pretty much assumed they weren’t suitable for mining, until Christian Buchner released a cuda kernel for them…

(So I would be curious to see the result… so if you join the competition…)

Regarding your comment about opensource and nvidia.

Opensource software are to support people using nvidia card not to support nvidia itself.

Lately nvidia came up with low power card which perform pretty well, so there are people interested in having miners for those card.

So they deserve miners as well…

Regarding the 5btc, it was based on download estimation (based on a previous miners I released), so it is probably a little high, I must admit, but as I said, I will probably not wait that it reaches that amount to release it… (now considering that the btc is going down… that’s clearly not a lot either…).

Also it must be noted, that I am not asking anyone to pay that amount, I am just asking people to participate (it is a crowd-funded project), just to clarify.
