[JCE]Fast & stable CN/v8/Heavy/Tube/XHV miner, CPU+GPU, Vega56 1800+ RX580 1200+

[JCE-Miner]

uPlexa

Will be in next version, code done and tested.
Stellite v8 is ready too, but i need a test pool and didn't find any yet, the testnet still says v7

Vishera performance: i admit this time, this is a real surprise. That's a modern AES Amd CPU, while i didn't test it since i've no such CPU (i've old Athlon64 and Ryzen, but not intermediate) i expected the perf to be at least on par.

Next version will restore Core2 and older CPU perf (sure), give a little +0.1% on Zen (quite sure, but it's in the margin of bench error) and add perf for Intel and those FX Cpu (not sure, theorical optim).
And add some new shitcoins like Swap, and uPlexa.

[JCE-Miner]

Online is
0.33j CPU Windows

* Increase/restore v8 speed
* uPlexa fork, as --variation 19
* Updated shitcoins: Saronite forked to Haven, XFH to Swap

About the speed, i tested it good on CPU I have, but did theorical fixes on CPU i don't have.
On Zen i got still +0.2% extra perf.

Fast as lightning! Thanks JCE!

[JCE-Miner]

It was ready before you asked, in test session.
Next release is 0.33b14 GPU with the backport of CPU version (including uPlexa) and the fix for --legacy eating too much CPU.

Hi ! no Linux build for the j release?

[JCE-Miner]

I give priority to the GPU version this time

Unfortunately the same speed as 0.33i CPU 

[JCE-Miner]

Ok, thanks for the report, so i'll separate the bulldozer-like assemblies from the Zen, since one got perf increase and the other perf decrease.
I'll pack this into the 0.33b14, with the GPU port of uPlexa and a more automatic legacy to avoid some GPU perf regressions.

Hi all,

Linux GPU: unlikely. I'm a niche miner (CPU and older GPUs) and adding the Linux concept would make it a niche of a niche, but a lot of dev time to do. The Win GPU is already like 15% of my fees but 90% of the support, the Linux version would be like 1% of my users for 95% of the support. I cannot afford this
Sometime i don't look at the market and do things for fun, like supporting the HD6000, but it remains an acceptable dev time. Linux GPU wouldn't.

Btw try TeamRed on Linux for v8 mining, it burns like fire

@PIOUPIOU99: yeah thanks, my new CPU miner also burns like fire 

Speed on Intel: i don't even have any big Intel CPU, i'm all AMD, as for the GPU (i've zero nVidia). But that's ok, i'll do some theorical optimizations for big Intel CPU too.
Can you tell me what exact CPU you have? Maybe a good config can close the gap with xmrstak. I know i must beat it by more than 1.5% to compensate for the devfee. It's true in most cases, but yeah maybe not the i7.

I do use it but competitive linux miner is always welcome

The great laik is asking for something probably have 580 8gb cards with timings mods doing 1400 cn heavy or something

[ganzocrypt]

I am getting a segmentation fault (core dump) on Ubuntu 18.

I am running the jce_cn_cpu_miner.linux.033i.zip

any idea?
Thx

I covered this miner in a video guide that should be helpful for beginners.

[JCE-Miner]

Woow, thank you, i take a look.

@all: sorry no support today, lacking of time. Otherwise the b14 GPU is now online

uPlexa fork for CPU and GPU
dedicated bulldozer v8 assembly x64
legacy mode is now automatic and tends to give slightly better perf on big rigs
The --legacy param remains to force this mode if needed.

about the assembly: it's only on pre-Zen aes AMD cpus, only x64, only xmr v8. No change in other cases.

I give priority to the GPU version this time

Pretty please ?

Hello

I can't find the link to download the GPU version, where is it?

Another thing, my CPU hashrate seems to be too high...

12:27:17 | Hashrate CPU Thread 0: 150.04 h/s
12:27:17 | Hashrate CPU Thread 1: 200.44 h/s
12:27:17 | Hashrate CPU Thread 2: 157.66 h/s
12:27:17 | Hashrate CPU Thread 3: 193.99 h/s
12:27:17 | Total: 702.11 h/s - Max: 949.68 h/s

*When I'm not using the PC, I get 1100 h/s

I'm using the 0.33j with a I5 4440
On this post I saw some ryzen and newer I5 getting only 300h/s, how is that possible?

[UnclWish]

Version GPU b14 - RX 580 8Gb cards - heavy algo - latest driver.
Miner closes after conneting to nicehash. He write "Pool changes difficulty..." as usual and than just closes without errors...
b13 works normal.

[JCE-Miner]

just tried and "works for me" but, what CPU do you have? There may be a conflict with the recent Bulldozer assembly, if you have a related processor.

edit: just found I put some BMI assembly in the bulldozer code, and not all bulldozer have BMI, so it may crash. If you have a modern but not Zen CPU, so it's probably the reason.

I use --no-cpu option... CPU is FX8320...

[JCE-Miner]

Bingo that's it, once again you saved my release from a stupid bug, thanks so much!

No matter you don't use the CPU to mine, it gets involved to do some partial hash to detect the broken shares (the red counter in the purple report). Otherwise, I couldn't tell the difference between a share refused by the pool because of bad fork, or real GPU memory/core failure. The impact is negligible on perf, but it may crash if the CPU side is wrong.

Note that i borrowed the idea from Claymore 10+ miner.

Are you some dev angel or something? Your config of RX580 8G + Nicehash + AthlonFX triggered three bugs I could not or barely have detected myself, that's crazy you found all of them

quick answer above: the speed depends on the algo, if you mine Turtle or uPlexa you'll get very high speed, but as any other miner would, so it's not better, just different.
uPlexa is an excellent coin to mine on an AES CPU, since the AES part is big and AES CPUs do it in a split second.

Yes, I'm mining angel

Just want to help. You did a lot of hard work. I'm testing and help...

[JCE-Miner]

I did one of my shameless undercover re-release of the b14. Should mine good on Athlon FX.
I also relaxed the max threads per GPU to 3 (request on github)
