CCminer 1.7.6-r10 Fork With Faster Neoscrypt, Lyra2RE and Lyra2REv2

[liquidproman]

Welcome to the discussion thread of on 名無し名誉名人(Nanashi Meiyo-Meijin)'s ccminer fork.
This thread is the branch of http://askmona.org/4314 in Askmona.


Features

• Faster Neoscrypt, Lyra2RE and Lyra2REv2 than the original ccminer
• Support for Pascal, Maxwell, Kepler, and Fermi GPUs
• Support Monacoin solo mining

In this zip file, ccminer_CUDA8.exe is by compiling in CUDA 8.0. So it needs the latest Nvidia GeForce drivers.
ccminer.exe is by compiling in CUDA 7.5 and suitable for compute capability 5.0 or less of the GPU.(ex.750, 750ti, Kepler or Fermi)

Old binaries and sources are here.(Names beginning with ccminer-windows are source files.)

Tips
In older GPU than compute capability 5.0, it may not be very fast. This problem can be solved by compiling in CUDA 7.5.
And 32bit ccminer is faster than 64bit one.

Lyra2re (r6, cuda 8 ) not good on my gtx750 (win7 64, latest nvidia driver), only 540khs, I got more then 1mhs with sp's cuda 7.5 version.
lyra2rev2 (r6, cuda8) is little bit faster for me then r5 cuda 7.5

[Amph]

wasn't this already released, what's the point of this? it was released by nicehash a few days ago

at first thought this was even faster, but it's not the case

no, it is not the same.

Thank you for testing.
Lyra2RE implementation is different in GTX9xx and GTX750.
Nanashi Meiyo-Meijin did not test to use GTX750 and GTX750ti. So he did not notice this problem.
He looks this thread. Maybe he will fix it in next update.

Nicehash forked Nanashi's ccminer1.5.80-r10.
This ccminer was released in May 27. And Nanashi switched the base ccminer from SP's one to tpruvot's one to support Pascal, Kepler and Fermi GPUs.
CCminer 1.7.6-r6 is faster than Nicehashminer.

i see the same hashrate mentioned on cryptoblog, what are the differences then if this is not the same?

Maybe a little patience is in order. The recent improvements to Lyra2 & Lyra2v2 are a welcome surprise as the prospects for
continued support of Cuda optimizations was not looking good.

These improvements were sponsored by Mona, which uses the lyra2v2 algo, I am hoping some of the talent can also be applied
to other algos if there is community support.

This is the best news I've seen in a long time and the timing couldn't be better with the release of Pascal, Cuda 8 & SM 6.1.

[liquidproman]

Thanks joblo. I couldn't say what I wanted to say.


Development schedule (Roughly)

• Debugging Lyra2RE
• Optimizing Neoscrypt
• Optimizing Cubehash in Lyra2REv2

Nanashi thinks several techniques used in Lyra2REv2 is applicable to other algorithms. The most typical algorithm are Lyra2RE and Neoscrypt.
I hope you test it or analyze it with Nsight in his next update.

if this is a long term project, then i'm supporting it, since sp want to say goodbye

it's good to have other that want to improve the code, especially for the new gpu

Nanashi Meiyo-Meijin has started this project since last month. It might change because this project has only just begun.
And he thinks this project is just a hobby. I hope he will have the fun of development.
but still he will rejoice if you support.

Trying to connect to miningrigrentals gives a bunch of 'stratum connection interrupted' spam and never connects.

Seems to work fine with just a straight connection to like Nicehash. Hope this isn't a sign of a miner fee that isn't reported.

[Velgelm]

now lastest version:
1.7.6-R6
and
1.7.6-R6-Fix
Wich version for maxwell cards ? (9xx series) ?

[liquidproman]

Now, Nanashi Meiyo Meijin released CCminer 1.7.6-r6-fix.
It is bugfix for 750 and 750ti, and optimized for Kepler and Fermi GPUs.
For Maxwell(like 9xx series) and Pascal GPUs, 1.7.6-r6 is probably faster than 1.7.6-r6-fix.

now lastest version:
1.7.6-R6
and
1.7.6-R6-Fix

You should use 1.7.6-r6. and dont forget to install latest Geforce drivers.

Did this problem occur with only this ccminer?
No one uses miningrigrentals in Askmona, so it might take a long time to resolve this problem.

thx

Yes, it only seems to happen with this version. SP's ccminer doesn't have this problem nor DJMs version.

MRR can be used to mine monacoin or any coin that uses lyra2v2 if you rent rigs for that.

The same 500+khs unfortunately. SP version can do 1mhs+

[liquidproman]

Thank you for testing.
Since the optimization of policy for ambiguous, also he does not have a 750, he is in trial and error now.
I think it is very interesting that no more speed unlike 9xx.

[liquidproman]

Nanashi Meiyo Meijin released CCminer 1.7.6-r6-fix2.
It is bugfix for 750 and 750ti.
