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

[papampi]

Hello,

I've been a user of NVOC for quite a while now on my two 1070 rigs (first 1.4 now 2.0) with very few issues. I really like the builds and want to say keep up the good work!

I'm now in the process of building some 1080ti machines (using Asus Z270-A boards) and have come across a problem (occurs with both 1.4 and 2.0 builds)...

I can get NVOC to boot into ubuntu by connecting to the intergrated GPU however get the usual xorg problem reboot message but can mine normally if I close the console window before the reboot happens and start ./3main manually but if I try to boot NVOC using the 1080ti I get a black screen after the ubuntu splash screen... I can SSH into the machine and it appears that it is mining...

I've had this sort of issue before with AMD machines and forcing nomodeset (or something like that) fixed the problem... however I've tried entering nomodeset at the grub menu but that doesn't do anything...

I'm at a bit of a loss with this, i'll continue playing but just wondered if anyone had come across this?

I'm presuming it's some sort of driver/xorg setup issue? I can boot off of my Win7 test SSD using the 1080ti and that works fine, so i'm pretty sure it's a software bug.

Thanks in advance!!

Download nvOC default xorg.conf and replace yours with it, reboot and see how it goes.

Code:

cd /home/m1/Downloads
wget -N https://raw.githubusercontent.com/papampi/nvOC_by_fullzero_Community_Release/19-2.1/xorg.conf
sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak
sudo cp /home/m1/Downloads/xorg.conf /etc/X11/xorg.conf
sudo reboot

If that didnt help try this:

Code:

sudo nvidia-xconfig -a --cool-bits=31 --allow-empty-initial-configuration --enable-all-gpus
sudo reboot

Try this:

for i in s u b; do echo $i | sudo tee /proc/sysrq-trigger; sleep 5; done  # reboot no matter the state

for i in s u o; do echo $i | sudo tee /proc/sysrq-trigger; sleep 5; done  # shutdown the system even when it is in a hanged state

Is there a script for a “rig offline” telegram notification that I’m missing? The telegram messages are awesome, but would be good to know if it powers down and stay down.

If system is going to be rebooted you will get notified from script that send the reboot command (watchdog or temp control), but if your rig freeze there is nothing to do.
You can set up an external watchdog like an RPi to check your rigs ping and ssh port and send you message if they were unreachable.

Hi
About this, does nvOC use the linux kernel watchdog ?

Unfortunately no.
Actually a card in one of my rigs making it hard freeze lately and I was reading and playing with sysctl to do a reboot on kernel panic with no success.

I changed

Code:

sudo reboot

in both watchdog and temp control to

Code:

sudo systemctl reboot --force

Didnt helped a bit.


Also added to /etc/sysctl.conf

Code:

kernel.panic = 1

And no help too,
The system freezes after 3-4 days of running clean with no logs, just a hard freeze.


Any one has good ideas to implement linux hardware kernel watchdog would be amazing to add ...

Thanks mate
Problem is system freezes and wont get to run those.
I need to enable kernel watchdog so it can reboot the frozen system.

Honestly papampi and the developers if you ever feel like this, I (and probably many) would have no problem with you guys setting up a permanent 1% fee for using your OS.  Its only fair, as it takes a lot of your time and effort to develop, de-bug, and answer everyone's questions.  It's something you don't have to do but you do anyway.  I for one appreciate your efforts.

I am all for it. I think the developers are doing an outstanding work and it would be fair to reward them.

Absolutely agree we need something like this

Hey guys, not sure where to put this, and this seems like the most logical place.  Mods please correct if it's an issue.  I have been using NVOC 19-1.4 for about a month and a half with 13x 1060's on an asrock h110 and the WTM profit switching.  I have added some coins including bitcoin gold and am somewhat familiar with the code but i'm not a programmer so please forgive any ignorance.  I attempted to add Verge-lyra2rev2 and while i am able to get it to mine successfully on ccminer, I am unable to differentiate between the different algos using the WTM profit switching.  It seems to always return the lowest XVG coin on WTM instead of the lyra2rev2 version.  My question is in papampi's screipt is there any way to specify something other than just the tag (XVG), but to use the coin id (207) to pull profit data on multi algo coins.  This would also be useful for coins like myriad.

Thanks in advance,

Ryansgt

Hi Ryansgt,
I had the same problem trying to mine XVG with lyra2rev2. The solution that I use, is to exclude the Groestl algorythm from Whattomine.com. You do that by clicking the "Groestl" button (that switch from blue to gray) excluding it.
You just plug the new JSON what to mine URL in 1bash and you are ready to go.

Unless you are mining a Groestl coin (highly unlikely since in general they are not very profitable), it should be a painless solution.

Yep, that's the best way going forward, we never expected this sort of deadlock, like a coin using multiple algos.

There should be a way of dealing with it but what you suggested is the easiest way for now.

Let me know if it has any bugs or problems.

I just ran the script and had it re-compile all 8 miners as a test.
I did not sit and watch all 8 compile but it completed "successfully" in less than 20 minutes on my lowly G3220.
I would say it works great.
Thanks again for the effort.

Yes, disabling groestl in WTM URL that you put in 1bash was also my solution that i proposed in my post here :
https://bitcointalk.org/index.php?action=profile;u=1157121;sa=showPosts;start=20

But i think it would be possible to filter multi-algo XVG coins like nicehash multi-algo added.
simply add one or two lines of code in forked python script papampi.

Here is what I propose :
Search this section in the python script :

Code:

# filter WTM coins by user selection only
for i in reversed (data):
     if i ["tag"] == "NICEHASH":
        i ["tag"] = "NICE-" + i ["algorithm"]. upper ()

for i in reversed (data):
     if i ["tag"] not in includedCoins:
        data.remove (i)

with adding XVG in WTM_SWITCHER python script

Code:

# filter WTM coins by user selection only
for i in reversed (data):
     if i ["tag"] == "NICEHASH":
        i ["tag"] = "NICE-" + i ["algorithm"]. upper ()
    if i ["tag"] == "Verge":
        i ["tag"] = "Verge-" + i ["algorithm"]. upper ()

for i in reversed (data):
     if i ["tag"] not in includedCoins:
        data.remove (i)

Of course, you will also have to modify 0miner minning command script file accordingly and also 1bash config file to update  parameters of coin XVG and OC_SPECIFIC_ALGO section too.

I think if you're familiar with code you'll be able to do it all.
You just have to take model on added nicehash-algo coins for other scripts files.

This is a propsition that I have not tested myself because I also think, as damnmad, that groestl is not profitable and therefore it is easier to disable it.

I have currently disabled the minning of XVG because of the sharp fall of recent days. Everything that was below 50,000 satochis was removed from my list of coin in WTM. So, suddenly I found myself mining ETH several times in recent days with using of WTM profit switch.

This is really amazing pap, it will help users who are not good at compiling or having issues with compiled miners.Will share it with the discord community too.

Please don't mind about people writing in bad tone, they don't understand the effort and time you are putting into this and there are really nice people up in here writing good things, they are the ones we really care about. Appreciate the work so much.

Like you say : " keep calm and carry on mining"

Is there a script for a “rig offline” telegram notification that I’m missing? The telegram messages are awesome, but would be good to know if it powers down and stay down.

If system is going to be rebooted you will get notified from script that send the reboot command (watchdog or temp control), but if your rig freeze there is nothing to do.
You can set up an external watchdog like an RPi to check your rigs ping and ssh port and send you message if they were unreachable.

I'll look into the Pi, would be great to set it up to ping and then restart if needed. Of course, finding the issue of the freeze is my priority and I think I have an idea now.

I have two rigs both mining ZCL on Supernova and this has happened twice that both rigs will freeze within a minute of eachother. I saw the first time while being connected via teamviewer that the server "disconnects" briefly within the miner and that watchdog will then re-start the 3main, get hung up and freeze. I assume this is what happened again. I would point to a hardware issue, but both separately going down at the same time with no telegram errors? Too much of a coincidence. I don't have any of the cards overclocked at this point, both systems were up for almost two days before the last freeze.

Anything you can think of in this regard?

I am in the process of updating the miners and re-compiling. Thanks!

So I have now tried the standard MPH_EQUIHASH switcher, MPH_ETHASH switcher and the SALFTER_MPH_PROFIT switchers from nvOC.
I have not yet tried the WTM switcher. That's next. 
I auto_exchange to ZEC on the MPH pool and that also works very well.
I have noticed from my test runs that I gain very little additional ZEC, if any additional, using these switchers than just pointing all my GPUs directly at ZEC.

It seems that the switching occurs often and is based on something like instantaneous profit margin on an exchange.
If that is what is happening, there is very little chance to:
have the miners switch
get the coin mined
into the wallet
confirmed
onto the exchange
and the exchange made before the switching equation is no longer valid
 
And frequently the switch formula will select a coin that only has the highest margin for a very short time, so if you make the time between profit checks too long your wasting time mining a suddenly low-profit coin.
It would seem that auto switching would be more advantageous if one had many rigs that could start the profit checking timeout in a staggered manner.
That way it is more likely that only one rig would be stuck mining a short-time-most-profitable coin.

Can someone help me with what I am missing in my thinking?
My farm is not that large so the benefits may be so small that I can't measure them.
The work done on the switchers is fantastic but I don't yet see the benefit.
Thanks.

whattomine has just added Innova Coin to the possible coin selection in its comprarative list.
If you want to add it to your WTM_SWITCHER list, it's still easy:

To add Innova (INN) (Neoscrypt) to the selection of cryptocurrency in 1bash script file and therefore also in the WTM switch:

1 / Find TZC Variables in 1bash file (just below the VIVO variables, you will copy / paste as a template Under TZC lines):

Code:

# Innova (INN)
# ## No Need to add add stratum+tcp:// to server address
INN_WORKER="$WORKERNAME"
INN_ADDRESS="INN_Wallet_Address"		# Donwnload InnovaCoin Wallet and Blockchain to obtain an address, avoid mining on cryptopia address
INN_POOL="pool.unimining.net" 	 			# 0.5% pool fee, Yiimp type Pool
INN_PORT="4235"
INN_PWD="c=INN"
INN_INTENSITY="17"

Add this below to the 0miner script file (in the same way below the command to launch the TZC ccminer and you can copy TZC but be careful to replace TZC_ by INN_ in the whole command):

Code:

	if [ $COIN == "INN" ]
		 then 
			HCD='/home/m1/KTccminer/ccminer'
			ADDR="$INN_ADDRESS.$INN_WORKER"
			screen -dmSL miner $HCD -a neoscrypt -o stratum+tcp://$INN_POOL:$INN_PORT -u $ADDR -p $INN_PWD -i $INN_INTENSITY
	fi

At the end of 1 bash file, you can also add INN coin in ALGO_SPECIFIC_OC section, Like This :

Code:

if [ $ALGO_SPECIFIC_OC == "YES" ]
then
  # Neoscrypt
  if [ $COIN == "FTC" -o $COIN == "ORB" -o $COIN == "PXC" -o $COIN == "VIVO" -o $COIN == "TZC" -o $COIN == "GBX" -o $COIN == "CRC" -o $COIN == "INN" -o $COIN == "DSR" -o $COIN == "NICE-NEOSCRYPT" ]
  then
    ALGORITHM="NEOSCRYPT"
    POWERLIMIT_WATTS=80
    __CORE_OVERCLOCK=150
    MEMORY_OVERCLOCK=800
  fi

Don't mine directly to Cryptopia Wallet Address because if Maintenance on INN Blockchain, cryptopia will be slow to reput online a wallet, and you risk to mine in the void for all  the time cryptopia INN wallet could be offline or désynchronised of official Blockchain.
Download their smaller wallet. There is a portable wallet for windows users.
https://innovacoin.info/#wallets

To consult your pool balance :
https://www.unimining.net/?address=INN_Wallet Address

You can mine INN on other pools :
http://www.zpool.ca/site/mining => 2% pool fee
http://pool.hashrefinery.com/ => 1.25% pool fee
https://altminer.net/ => 0.9% fee
https://www.lycheebit.com/ => 1% fee

More pools on their webpage, I do not have all consulted :
https://innovacoin.info/pools/

Be carefull in Mining VIVO coin, i mine it but it seems that his blockchain is pericliting or desynchronize on severals pools.

If you are minning VIVO, Please let US a Message to tell everyone where is the good blockchain.

Because of this désynchonized VIVO blockchain, i prbably loose 0.5 Vivo ...even if bulwarkpool.com confims all blocks it mine on the wrong blockchain. But i think it's not a good solution to resolve.

I just saw thant hashraffinery seems to have the same problem but i'm not sure because they don't precise tha coins they are desynchronized

Please tell everyone what pool your are using.

Is there a way to use MPH pool auto exchange feature using papampi WTM auto switching?  I have not tried this but i assume if i point all the different coins to the correct 72XXX ports that it would work?  Has anyone tried this or have any ideas on how to implement this in the code?

Yes, and thats what I do
Just set your coins with normal 17xxx port and add them to wtm_coins

Edit:
Normal port 20xxx should be used, 17xxx is auto algo switch.

I dont have any amd rigs and dont use rxOC
But I think the set of compile miners has same path as rxOC, but others like ethminer, dstm, bminer, ... may have different path in rxOC that should be changed in 3main/1bash or move them to the appropriate location.

@papampi re: hardware watchdog

Sorry for being brief here, but I'll try to give you some pointers.

you should look at ubuntu package watchdog and the watchdogd daemon. When implemented correctly (I hope it is) with the help of the kernel is should work as hardware watchdog timer (on mobos where the hardware watchdog can be enabled in bios or where it's enabled by default).

It works by starting watchdogd which is a daemon that will reset a watchdog (hardware bit in the cpu/mobo) once a minute. Once started, if watchdogd does not reset the timer, a hardware reset occurs.

Sometimes it's possible that there's a hardware issue with the gpus where a simple reset will not be good and you might need a physical power on-off.

hth, bytiges.

Thanks mate
I know how it works, and I can load watchdog manually but couldn't get it to auto start on system boot.
Also no idea which modules to remove from blacklist .
