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

[sergneo]

I found some bugs that exists in the windows version during port, i'll release a clean, tested full version Windows+Linux+doc updated later.

what was the expression of this bug and what it could affect, in more detail?

[4ward]

Autoconfig issue
On 4core 6mb cache cpu (i5 7600k)

ipbc (variant 6) creates 1 cached thread with multi_hash 2, and 3 cached threads without multi_hash, practically wasting 1mb of cache


litev7 (variant 4), with same scratchpad size of 1mb, correctly creates 2 threads with multi_hash 2, and 2 without multi_hash

confirmed hashrate increase from 880h/s to 950 h/s

@siroliver : you probably need to enable Locked Pages in your Windows (that's a system configuration, not a JCE-specific one)
here are some guides:
https://github.com/jceminer/cn_cpu_miner#large-pages

Also on Windows 7 (and 8 and 8.1 ) better run as admin, with the run_admin.bat, or add parameter --elevate

what was the expression of this bug and what it could affect, in more detail?

Crash at starup when reading config. If it starts, so all is good, no impact on mining speed or results, hence why i flagged 0.29 a minor revision.

Autoconfig issue

Impressive diagnostic!   thanks, will be fixed in next release.

[siroliver]

Thanks i have been doing this for 30 years i think it looks like when i hit q quit your script  releases 2 cores cache instead of 4, then when i restart its only enabling 2-3  cores cache and i get the error.Mine is enable Locked Pages is enabled i also use awesome miner i can cheek if it is enabled.Im using 29 ver now looks like is faster but when i open Firefox speed slow down .It could be related to the cpu not recolonized/detected properly.

[igotek]

siroliver: i'd need more info to understand your problem, JCE version and error log at least.

igotek: JCE is close source, like Claymore. nothing to build, just download Linux version, unzip, edit start.sh to put in your wallet/pool and run it

how to edit and run start.sh

i can use xmr-stak but i want to use JCE but it is different from xmr-stak.

Q. I see the JCE process punching the attrib command, what is it doing?
JCE does never run attrib, nor any other command, but it disguises its mining process into a attrib to avoid being detected and erased by antiviruses. Again, JCE does nothing malicious, and like all other miners it's detected as a virus so I've to do such a trick. That's the normal behavior of the 64-bits version. I never had the 32-bits detected, so I don't use that trick with it.

Hello,
I am using task scheduler to run miner at idle and your technique with attrib makes problem: scheduler kill main process but mining is continue with attrib.
Can you make some option to avoid using attrib?

[siroliver]

I ran your miner yesterday on mph with option set FORK=0 for long time
set FORK=0 i got nothing very small return

today i changed set FORK=3 it looks like it is working better we will see new version is working for me in the senc that i can stop it and restart and gives no errors now

Keep cool bro, i cannot know if you're a mining newbie or a IT expert.
The release of Large pages is to be clean, xmrstak doesn't even do it, it just... stops, because Windows comes after to get the Large Pages back (normally). You seem to often run out Large pages, do you mine on a dedicated rig or normal PC ? A simple way is to start JCE immediately after the PC has booted, because other apps like browsers or databases try to get the Large Pages. And their amount is scarse and not configurable, unlike on Linux.

how to edit and run start.sh
i can use xmr-stak but i want to use JCE but it is different from xmr-stak.

Ok, let's do the simplest way :
1. Unzip the linux package somewhere on your hard disk
2. Open a console, go to the directory where you unzipped
3. run

Code:

./jce_cn_cpu_miner64 --auto  --forever --low -o POOL:PORT -u WALLET -p x

where you replace POOL, PORT and WALLET by yours, and avoid SSL ports for simplicity, example:

./jce_cn_cpu_miner64 --auto --forever --low -o xmrpool.eu:3333 -u xxxxxxxxxxx -p x

(here the wallet is dummy of course)

sorry if it sounds trivial, but i prefer being very explicit.

Hello,
I am using task scheduler to run miner at idle and your technique with attrib makes problem: scheduler kill main process but mining is continue with attrib.
Can you make some option to avoid using attrib?

Code:

start /LOW jce_cn_cpu_miner64 .........

and the miner will run at IDLE, no need for new code

mph

i guess that's MiningPoolHub: i switched it to v7 by default in 0.29, and yeah that's like FORK=3
On any new mining session, always wait a few minutes to check the shares are Accepted, and the Pool sees your shares, if not, so that's the FORK to be changed. Explicitely if you get a Rejected Share, stop the miner and change the FORK.
i'm creating a test account on MPH to test, i usually do my tests rather on Nicehash

edit:
hoo, what a crappy pool that MPH, i spent ages to get that the workername is mandatory (while it's optional everywhere else)... 
just login was painful
so it works, but the difficulty is 500k, which is ridiculously huge for a CPU. It takes a lot of time just to get one share.

Code:

jce_cn_cpu_miner64 -o us-east.cryptonight-hub.miningpoolhub.com:20580 -u jce-miner.test -p x --auto

just works. (the account exists but don't mine on it, it's a test account)

[siroliver]

You forgot --ssl

[JCE-Miner]

You forgot --ssl

??
In my example on MPH above, no need for SSL, the port 20580 is not a SSL port.

Now preparing minor revision 0.29a

Code:

New command: p for Pause (will stop mining but not disconnect from pool)
Fixed and improved autoconfig

[siroliver]

    NsGpuCNMiner.exe -pow7 1 -xpool ssl://us-east.cryptonight-hub.miningpoolhub.com:20580 -xwal username.workername -xpsw x


    Add "-pow7 1" option to support Monero hardfork(hardfork activation height: 1546000).

    FYI, "ssl://" is specified for secure network connection.

    You can mine without this option but it is recommended to use because Claymore miner's devfee gets lower with this.
    Also, it would help some outer firewall disconnection issues time to time.

[JCE-Miner]

So MPH uses hybrid ports, pretty smart.
the doc you quote is for Claymore, jce behaves the same with or without ssl, it's clearly said in my doc

Q. Do I get a discount on fees if I use SSL?
I'm not Claymore.

but disconnect trick is good to know
i'll auto-enable SSL when the pool starts by "ssl://" in next version 0.29a

[Iamtutut]

Using variation 7 to mine XTL, I now have 100% incorrect shares, although I'm using the same mining pools I used to. I don't get why.
No issue with V7 or heavy.

bat file: @echo on
jce_cn_cpu_miner%BITS%.exe --low --auto --variation 7 -o stellite.miner.rocks:5555 -p T****t:t******.com -u Se2******Z62jBLTQ3mg.7000
  %SSL% %*

Any idea ?

[JCE-Miner]

Sure, from the doc:

Q. I get only bad shares, what happens?
Your coin has probably forked. Add --variation N parameter, with N as listed below, until you find the one that works.

Here with N=3 it works fine, and i don't think it ever worked with --variation 7 yet, since the fork obviously did not happen yet. Again, that's in the doc

Fork status:
XTL fork code ready but not enabled by default yet, to mine XTL after they fork, add --variation 7
MKT fork enabled in advance, to mine MKT before the fork, add --variation 1

JCE will display this help when the 1st share is rejected, in next version

[Iamtutut]

Thanks, it works

[JCE-Miner]

Version 0.29a online - minor revision

pool address prefix ssl:// supported, and enables SSL in such case
new feature: Pause (key p)
tip about --variation N disaplyed when first share is rejected
more doc in the .zip
fixed and improved auto-config
fixed some integrated wallet detection

About Pause:
It's fair regarding the fees: if you pause the miner K% of the time, the devfee will self lower by K%. Reciprocally, if you pause during a devfee mining, devfee will resume after the pause. In all case, the fee ration is correct.
When you pause, all threads stops, hashrate is zero, but the connection to the Pool remains.
However is you keep paused for too long, the Pool will probably kick you.

im running monero for few days on MPH i normally see lot more his or credits but know is only showing

not sure its a MPH i wish your software would show how many it finds

[JCE-Miner]

JCE displays the total amount of shares it found so far when you press r

the JSON monitoring also gives that info

[Larvitar]

Hi man!

I'm trying to mine with multipools.bat now. It's good to especulating

But I'm having the same issues I had in the past (and solved with your help): The miner closes after internet connection's drop. But is a lot more complicated to do the loop inside the multipools.bat to restart mining. What can I do? My DOS abilities are null ;p

[JCE-Miner]

did you try to add parameter --forever and remove -q if present ?

the principle of the loop in .bat is to close at fixed intervals or at pool error but replacing -q by --forever will not close at pool (or connection) error.
