[OS] nvOC easy-to-use Linux Nvidia Mining

[Stubo]

I have been spending a bit of time reading through all of the bash scripts that make up nvOC. I urge everybody to do that because then you will learn both how it works and how you may be to take advantage of some of the vast functionality that is offered. To make that easier to do, I found a python script "beautify_bash.py" that you can run against them (1bash, 2unix, 3main, etc.) to make them more readable.

https://github.com/ewiger/beautify_bash

It basically just reformats the code with the proper syntax indentation for loops and if statements. The first thing that I did with the 19-1.4 release the other day was to beautify all of the scripts, then make my personal miner tweaks to those versions and finally deploy those to my miners. I have found no issues from doing this. The basic steps to get it going are:

-Download the zip file to your PC, unzip it to get to beautify_bash.py
-Use WinSCP or suitable substitute to sftp it down to your rig(s) in /home/m1 directory
-Login to rig, make the script executable "chmod 750 beautify_bash.py"
-Execute against the scripts you use:
./beautify_bash.py 1bash
./beautify_bash.py 2unix
./beautify_bash.py 3main
./beautify_bash.py 4update
./beautify_bash.py IAmNotAJeep_and_Maxximus007_WATCHDOG
..etc

It will beautify the script and leave a copy of the original as <filename>~. Perhaps there is some reason for releasing the scripts with no syntax formatting as they are but I have yet to find it.

Hope this helps.

I have started to not use standard formatting with bash at all.  I wasn't really thinking about readability for others.  This script looks interesting; can probably save a lot of time when used systematically.

I would also add that it can point out problems as well. In 19-1.3, it pointed out extra fi's in 2 of the scripts. It looks like you cleaned them up for 19-1.4.

Nicely done and fast as always

Thanks a lot damNmad

Thanks mate, I was following this coin from past two months (trusted it somehow), good to see its ticking every boxes now

Just installed this nvoc on one of my rigs, looks good. So questions though (no, I did not read all the pages..):

- Is there a way to limit telegram messages to be sent only when there is something wrong, i.e. reboot of server or miner is needed ?
- My rig has some stability issues, I am mining Ethereum with ethminer. In order to track the GPUs causing problems they would have to be run as separate instances/sessions, (xmos does this by default). Any plans for implementing such feature? If not maybe I try with claymore or plug in xmos USB stick, adjust overclock settings and copy them to nvOC.

You can set telegram to no, but may lose some info, or set to high times like 1440 (once a day)
Papampi telegram will send alerts either way

Is anyone having a problem mining with skunk algo with ccminer.
I have set it up, but can't get it to work.
I tested the syntax from the command line, and this is the result I get (I have replaced my real username with "username" in this example):

m1@m1-desktop:~$ /home/m1/TPccminer/ccminer -a skunk -o stratum+tcp://zpools.de:3300 -u username.miner1 -p x -i 22
*** ccminer 2.2 for nVidia GPUs by tpruvot@github ***
    Built with the nVidia CUDA Toolkit 8.0 64-bits

  Originally based on Christian Buchner and Christian H. project
  Include some algos from alexis78, djm34, sp, tsiv and klausT.

I've implemented an idea where i've reduced the number of telegram notifications by integrating with https://healthchecks.io/checks/
I have a crontab job run every 5 minutes where I curl the healthchecks.io checks:
*/5 * * * * curl -fsS --retry 3 https://hchk.io/CHECK_ID > /dev/null

And in there healthchecks.io/checks you would configure how often you would expect to be notified and when you would raise an issue. There is an integration with Telegram, where the bot can be configured to send you an message in case of ping not received during the grace period.

And then the Bali_TELEGRAM_ALERTS can be scheduled to not send messages at all, only when WATCHDOG seems appropriate.

I suggest you to read the notes and comments on /home/m1/kk003_telegram and see if its ok for your needs.
Or you can go here:
https://pastebin.com/vPnb6TKn

and see.

I guess if you leave empty var USER_CUSTOM_TIMES_TO_SEND_TELEGRAM you'll get only warnings (including warnings from IAmNotAJeep_and_Maxximus007_WATCHDOG).

Form:

Code:

USER_CUSTOM_TIMES_TO_SEND_TELEGRAM=("12:00" "18:00" "21:32")

To:

Code:

USER_CUSTOM_TIMES_TO_SEND_TELEGRAM=()

I did not do this check, hope it works for you (I think so).
Let me know if it does not and I'll fix it.

You may too set USER_CUSTOM_TIMES_TO_SEND_TELEGRAM like this:

Code:

USER_CUSTOM_TIMES_TO_SEND_TELEGRAM=("18:00")

to get a telegram once a day at 18:00 (or any other time/s of day you want)

Here is the warnings list (most of them):

Code:

# Some warning you can choose to get via telegram or not 
SEND_WARNING_SYSTEM_RESTARTED="YES" # YES or NO
SEND_WARNING_XORG_RESTARTED="YES"   # YES or NO
SEND_WARNING_LOAD_AVERAGE="YES"     # YES or NO
SEND_WARNING_CHECK_DISPLAY="YES"    # YES or NO
SEND_WARNING_WHEN_NO_L_ON_SCREEN="YES"  # YES or NO     YES send a telegram when screen is not starting miner with -L (create log file)

And some info you may choose to get or not in your telegram msg:

Code:

# some information you can choose to receive or not on your telegram msg
SEND_REBOOT_REQUIRED="YES"      # YES or NO
SEND_WORKERNAME="YES"           # YES or NO
SEND_MINING_COIN="YES"          # YES or NO

SEND_RAM="YES"              # YES or NO
SEND_CPU_MODEL="YES"            # YES or NO
SEND_LOGGED_USERS="YES"         # YES or NO
 
CUSTOMIZE_SYSTEM_NAME=""        # "PRIVATE_IP" or "PUBLIC_IP" or "AnY CusTom nAme you want here", if empty it uses the system's hostname
                    # This is the main header you'll get in your telegram message
                    # PRIVATE_IP will use your private ip/s (remenber you may have more than one)
                    # PUBLIC_IP will use your public ip

Warnings auto-clear when system gets back to normal.

To Fullzero. Hi i have a very very wierd situation going on with my "Drunken Rig" damnmad and i have tried numerous times to get it to work with no avail. The rig seems to have a mind of its own we dont know if its xorg or coolbits the culprit but it tends to Overclock some cards and some not and at a random order also it tends to control some of the power values and some not so its like it has a permission issue but it doesnt seem to want to listen regardless of what we do. can you contact me via pm or on discord to see if you can maybe connect to the rig and see whats up. Damnmad has a bunch of logs from the rig maybe they can help resolve the issue also?

Yeah, the thing is, his RIG throwing this Error while running 1bash;

"ERROR: The attribute 'GPUGraphicsClockOffset' specified in assignment '[gpu:0]/GPUGraphicsClockOffset[2]=175' cannot be
       assigned (it is a read-only attribute)."

His RIG is using mixed cards like 970, 1050, 1060 as well,  i tried to edit the xorg config file, but no luck, he isn't able to OC some of cards at all!

I believe, we have seen this sort of error, don't have those cards to test it personally, might need to edit the cool bits according to the card or I might be completely wrong.

Correction i could Overclock the cards via "Nvidia Server" Manually its xorg and or cool that doesnt auto overclock on 1bash start.

zm 0.5.4 is out which adds some nice improvements to the telemetry interface.  I have rolled it out on all my nvOC 0019-1.4 rigs with no issues.

I know it has been discussed recently and I hope to see a way to collect data from multiple rigs and present it in a single browser window.  With the 0.5.4 update, the telemetry now looks like this:



Which I think is a nicer view into what your rigs are doing than this:



But this 2nd view does provide some nice nvOS specific data.

Some sort of dashboard view of all your rigs would be very nice.  It would of course depend on what miner(s) you're running to pull the stats to collect them into a consistent view.

Hi guys can you help me how to add more algo on SALTER_NICEHASH? I want to add cryptonight so that it can automatically switch to that algo pls tnx tnx tnx

Hi Fullzero or anyone here figure it how? i tried to copy the settings of other algo and change the settings but it gets buggy and got insane income result lol

I will add looking into modifying SALFTER_NICEHASH_PROFIT_SWITCHING to work with XMR/ Cryptonight.

Yey thanks so much i will wait for it

I installed nvoc 19 1.4 it works fine except - auto temp control
I'm constantly getting this message -

Power limit for GPU 00000000:0E:00.0 was set to 150.00 W from 150.00 W.

Warning: persistence mode is disabled on this device. This settings will go back to default as soon as driver unloads (e.g. last application like nvidia-smi or cuda application terminates). Run with [--help | -h] switch to get more information on how to enable persistence mode.

All done.
GPU 12, Target temp: 70, Current: 58, Diff: 12, Fan: 30, Power: 50

I've setup PL to 150W but somehow it shows Power 50
Can you help me please?
 

Open Maxximus007_AUTO_TEMPERATURE_CONTROL

find this line :

Code:

POWERLIMIT=$(echo -n $PWRLIMIT | tail -c -5 | head -c -3 )

and change it with :

Code:

POWERLIMIT=$(echo -n $PWRLIMIT | tail -c -6 | head -c -3 )

You can also edit your host name with

Code:

sudo nano /etc/hosts
sudo nano /etc/hostname

Thank you temp control is working now it shows my PL (150W)

but sudo nano /etc/hosts and sudo nano /etc/hostname shows same picture

I don't know if this will totally fix the issue but the sudo error re: host resolution can be corrected by fixing the hostname. In 19-1.4, there is an issue in that the hostname in /etc/hosts and /etc/hostname do not match. IIRC, /etc/hostname has 19_1_4 and /etc/hosts has m1-desktop. Edit one or the other or both and make them match. If you edit /etc/hostname, you will have to reboot.

Hope this helps.

Thank you for your response.
If I'm not mistaken they looks same

[dbolivar]

Guys, is there a real-world difference between enabling or disabling GPUPowerMizer? I notice I can achieve the same overclocking values with or without this setting, getting about the same hashrates. But maybe it's good (or not!) for something... From the NVIDIA documentation, it's related to dynamic power management, but since we lock the frequencies and power limit, does it have any use? Thanks!

All,

Apologies if this was covered somewhere in the previous 267 pages but I'm having a struggle getting the .IMG to burn to a USB. I download it (tried 3 different PCs, all on Windows 10), used HDD Raw Copy and Etcher, to write the image to a 32GB Lexan (per Vosk's recommendation) and a few others and keep running into the same issue. It seems it only writes the 1hash file and nothing else. It splits the USD into two partitions, one contains the 1hash, and the other is "unformatted."

I'm sure, and kind of hoping that, I'm "missing some mundane detail." Does anyone have ideas what is going wrong?

Thanks

Joe
