Regarding Cryptonight ASICs

will you update your version of xmrig with the upcoming fork where Monero and Sumokoin are going to update the algorithm, I dig SUMO I am relevant this coin for example.

[2010phenix]

xmrig already say that add support after Sumo move to cryptonight_heavy

[Foudge]

I will merge with xmrig branch and redo some optimization for Core2 if necessary.
The PoW algorithm update is scheduled for April 6. Not sure I'll be on time.

[sergneo]

@Foudge I mining Sumokoin , you'll be able to enable PoW SUMO ? Date fork has not been determined, but promise after Monero.

[Foudge]

I don't know. If the difference is like between cryptonight and cryptonight-lite, it will be easy.
You have a link about the algorithm PoW evolution?

Fork Block Height set at 117600 (on abt April 4th). Binaries will be released soon. Following the fork the light Qt GUI wallet will be released featuring remote node connection ability (it is ready for release). Web wallet is expected to be released soon as well.

@ Foudge this is his(SUMO) new algo repo: https://github.com/curie-kief/pow_test/commits/master

and how work: https://github.com/curie-kief/cryptonote-heavy-design

@Foudge https://github.com/xmrig/xmrig/releases/tag/v2.6.0-beta1
xmrig has just released a new version with Added Cryptonight-Heavy support for Sumokoin ASIC resistance fork.
You can now take the basis to update the optimization Core2 Duo, Quad as in your version of F4 ?

@Foudge fork is done, miners are working, can now optimize the code for core 2 duo ?

[sergneo]

@Foudge where did you go?

[sergneo]

@Foudge it seems the miner v2.6.0-beta2 is not very optimized for Core2 Duo Quad especially under Xeon.
cryptonight-heavy issues at E5440 43.5 H / s on 4 threads , on 3 threads 35 H/s. And this despite the fact that the cache L2 12Mb. Especially on a Quad with a 6Mb L2 on 3 threads gives more than 2. 22H/s vs 14H/s.

[sergneo]

@Foudge But even more optimization is needed Monero v7

[sergneo]

xmrig has already released a version https://github.com/xmrig/xmrig/releases/tag/v2.6.0-beta3 Oh. Please add to your version of pow Monero V7. Your version for no AES faster.

[Foudge]

I have a bad news. I stopped mining with my CPU and stopped develop this project. I started the merge but it's not functionnal and need work and time to do all the necessary.

But if you have a non-AES CPU, all is not lost. I discovered 3 weeks ago another miner : JCE Cryptonote CPU Miner
It is closed source, have fee, but it is really fast, and faster than my version of XMRig on this processors!
Besides it is up-to-date, support many algo variations and many coins and developper is very active.
Github : https://github.com/jceminer/cn_cpu_miner
Bitcointalk : https://bitcointalk.org/index.php?topic=3281187.0

I already used it, it works very well! I recommand it.

[Foudge]

In cryptomining, I will maybe develop algo rewriting on GPU (maybe an another XMRig fork). The idea is to use an API faster than OpenCL or CUDA : Vulkan
But how many time to control GPU programing and this new API? What is the gain to be hoped for? I don't know. If it's just 10% boost, no need to spend tens of hours on this project. So not sur at all if this project will born, but it's certain that development on CPU is over for me.

[sergneo]

This is of course very sorry that you stopped work :( If you would have released at least one version after the fork would be good. JCE Cryptonote CPU Miner may be faster, but I have 100 computers are on the local network and do not have direct access to the Internet, ie this miner is not for me it does not work for me. The developer did something stupid. He doesn't have the http monitor, but I really need it.

[2010phenix]

JCE Cryptonote CPU Miner and not even start on old Windows x32

[sergneo]

@2010phenix no http monitor, be sure to direct Internet access to the donation pool, 3% for the old CPU. Private code. Miner has no future, the developer will not work on it much. Reject share Minergate.

[sergneo]

@Foudge please, could you combine your F4 version with the latest xmrig 2.5.3 version ? For your miner to work at least after the fork with Monero V7. Respond.
