[ mining os ] nvoc

[Temporel]

Guys, I am having issues unzipping the NVOS (nvOC_v0019.zip) on both MAC and PC. The file size shows 6,436,759,477 bytes (6.44 GB on disk), but when I am trying to unzip the size of the image is getting huge (over 250GB!). I downloaded the google drive version of NVOS zip from this forum. Has anyone encountered this issue and can give some advice? Thank you in advance!

if you really tried on 2 different computers then your original must be corrupted. Try downloading it again.

Guys; I thought of keeping all the best OC settings in one place for all the available cards in the market.

I would need your help to input your best OC finds bit of details; happy to update it time to time; it would help us hit the rock bottom (even for a beginner).

You can PM me or Post a reply on this post or request on this post :

https://bitcointalk.org/index.php?topic=2176936

Hope I get good support from our nvOC community members to make this possible

I've only started; any suggestions welcome

I have added a link to the OP.  This should be helpful for members.  

Thanks fullzero for that

Guys what is SRR option?

also when i set minimum temp=25 or lower, it wont go lower than 30

(using v0019 with updating)

SRR = Simple Rig Resetter
it's a little board that connects to your power/reset pins on the motherboard, it then listens for heartbeats from specific rigs, when the heartbeat stops, it means the rig froze, it hard re-sets the specific rig.

I've been using one for a few months, saved me lots of time at the beginning.

Does Linux ever hard freeze?
Been using ubuntu since 2006,
Got lucky and have never experienced it.

Linux is very stable, but it won't protect you from hardware issues so if you OC the cards too much any OS will freeze, updates can cause issues, drivers etc.
Use case:
Remote rigs - it can correct a remote issue in minutes before you're even aware.
USB failure issues - I've had USB issues with the Asrock BTC+ 110H boards where sometimes they don't recognize the USB and reboot into bios... this cycles the power and the USB is seen again.
I've had rigs hang when OC'ing cards too hard, or heat buildup during summer at a remote site.
The next Mobo manufacturer that includes this functionality in their mining Mobo's is gonna do well, all server class machines already have similar capabilities for the same reasons.

guys, when I do putty, what is the username and password?

Default user is m1 and password is miner1

you are the best! thanks! oh and how do we change the bash file or the miner settings from putty? and how to stop the miner and start? thanks!

For modify 1bash from putty just do

nano 1bash

To reset your miner follow this, thanks @papampi

In v0019 you dont need to kill 3main. just killing miner will make wdog re-init 3main and run it with your new edited 1bash
but if you want to kill best way is :

Code:

pkill -e screen # to kill miner, wdog and temp
pkill -f 3main # to kill 3main 
bash /home/m1/3main # to load 3main again

one line cmd :

Code:

pkill -e screen && pkill -f 3main && bash /home/m1/3main & 

Click enter when 3main loaded, and miner started, dont do ctrl+c

hi need help is there any way i can schedule miner to run like only from 6pm-11am ?

Yes it does... Of course it historically has always been more stable than, say, Windows, but hard freezes can and do happen mostly for these two reasons: kernel (including modules) bugs, and hardware issues, as pointed before. More rarely, a bug in the "init" process can also do this. These can trigger what's called in the Unix world a "kernel panic", the equivalent of Windows' BSOD. In some cases, even in a kernel trap, you can do some debugging (like dumping memory) and take a few actions, like syncing the filesystem and rebooting, but not always.

That's one of the reasons why enterprise and "stable" distros (RHEL / CentOS, SLES, Debian stable, Ubuntu LTS) are more conservative with new kernel and software versions. They tend to use the long-term kernel tree, which doesn't introduce too many features, focusing more on fixing bugs.

Now, personally, with nvOC (which uses Ubuntu LTS) I've never had a kernel panic. But you never know, if you need full remote control this SRR seems a cool addition, or an intelligent power switch, KVM etc.

There are NO such limitations; nvOC is designed to max of 13 cards without any modification of 1bash & 3main (can add more by modifying these two files). Try to verify the risers (swap them around with the working ones).

Hash rates dropped with your 8 cards??

OK, I think same - no limitations...

I've rate ~6400 Sol/s with 8 cards.

After connection next 3 cards, rate dropped to ~5100 Sol/s only. nvOS didn't detect more than 8 cards, as you can saw on nvidia-smi.

Well, risers maybe problem - I'm novice in mining, so I ordered more types. I using version v006C and v008S. On cards plugged on v006C blinking LEDs below power connectors on card. I've ordered 13 pcs of v008S (these: www.aliexpress.com/item/TISHRIC-2018-Hot-VER008S-Molex-4PIN-15PIN-SATA-6PIN-3-in-1-PCIE-PCI-Express-Riser/32830747032.html). I hope that will works well.

Many thanks :-)

What is your CPU ?
I had the exact same issue with AsRock and 12 Ti's and it all went smooth when i switched the CPU's from the rig with my own. For me it worked putting a i5 7400 on the motherboard. Maybe it works with a less expensive CPU but it was the only one i had around.

[Bibi187]

hi need help is there any way i can schedule miner to run like only from 6pm-11am ?

U have multiple solution, depend what u want exactly.

PC have to be turned off or only mining process ?

If u need to pc be turned off, you probably can buy a power timer.

If u let PC run and just turn off miner, u can do a crontab

Code:

crontab -e 0 11 * * * miner1 pkill -e screen && pkill -f 3main
contrab -e 0 18 * * * miner1 bash /home/m1/3main & 

First line will kill your process every day at 11am
Second line will launch miner process every day at 6pm (18)

Been using ubuntu since 2006,

I'm running my own 176 cards and hosting another 388 for friends and family and turning this into a hosting business.

After trying basically all the setups possible (with 6,7,8,9, 13 cards) i've settled on 3 cards per rig. Never looking back.

If you're using second hand HP Compaq DC7800 or DC7900 (you get it for 40 usd in my country with 4 G RAM, 3 pciex slots) and a dual core duo CPU you get the vPro awesomeness of full remote power on and off and Intel AMT out of band remote management included. Nobody can't beat that. Upgrade the firmware on the motherboards and BAM! you have a remote KVM built in. You can see your screen and do whatever you want from anywhere in the world.

If i am running 1080 cards and above, i buy a 750 W server PSU for another 50 USD and i can have a full rig up and running with the total cost of 90 USD per rig. If i am running 1060 cards, i simply upgrade for 10 usd the PSU in the SFF desktop to a 500 W one...

All the rigs are beautiful, no cabling nightmare, whenever a rig crashes i scripted a full power cycle using a raspberry pi as a watchdog.
SRR's are expensive when you have a lot of rigs.

I've seen this too; mostly a restart should fix or try to fire those url's (mph, coinbase, nicehash) in RIG's browser, see whether you can browse through.

Hi guys,

I have recently built a new rig with 13 P106-100 ASUS cards on nv0019 running -200cc 1550mc and PL90. I have a weird problem that after some time the hashrate on all cards drop by 50% or more and doesn't go back up, the miner doesn't restart and it just keeps running with lower hashrate.  This time it did this after 7 hours , with 7 cards running it was up for over 12hours and no problems. Has anyone experienced this before and maybe you know where the problem is?

I am obviously running headless and using SSH to monitor the rig and adjust the settings.

PS. The miner or the OS doesn't restart the miner or reboot the system, just the hashrate drops pretty badly from 328 to 140 MH/s.

Thanks in advance to everyone who can help and also thanks to fullzero for the new version!

How is the temperature of your cards? Have you configured nvOC to use auto temp control? If you have, it may be the case that you set the temp too low for what can be reached with 100% fan speed. In this case, auto temp control will smartly reduce the power limit to cool the cards, but of course this reduces the hash rate. Just a guess...

The highest temp I have on these cards is 61 degrees and fans are running no more than 67% so I doubt that these causes the problem. Unfortunately in P106-100 headless mode neither watchdog nor tempcontrol works so I do not use those.

SRR's are expensive when you have a lot of rigs.

That's 188 mini rigs if my math is correct, and you have to add cabling/switches/power for all the cabling so 5x48 ports switches can handle that but then you still have a ton of cables (and time to manage it all) and if you go second hand for the switches, one switch dies and brings down 48 rigs, anyway you slice it you need cabling and can have many cards go down depending on the nature of your failure.
Then there is heat.
Of course the above can be great in the right circumstances.

FYI - 1 SRR controls 8 rigs, there should be a daughterboard available eventually to add 32 for a total of 40 rigs for 1 SRR.
I'm very happy with it.

Seems like there is a problem with Klaust and Neoscrypt in linux
There is an open ticket for that
https://github.com/KlausT/ccminer/issues/49

I can not install KTccminer on NVOCv019.

I looked at your post on their incident ticket page and I find that 4 days ago you were able to compile it correctly on your machine.
Unfortunately, I have not managed to do the same with my Biostar TB250-BTC PRO (Socket 1151) and my 2 x ASUS GTX1070 DUAL.

I use the script (s) of Scott ALlfter (alias Salfter) and I went on his page here: https://gitlab.com/salfter/mph_switch/tree/master. This page explains how to add the Cryptonight and Sia miners but I was unable to compile by following the command lines given by Salfter.

./autoreconf.sh does not exist in the KTccminer directory
and
./configure --with-cuda- / usr / local / cuda-8.0 also returns errors after executing the file: autogen.sh

here is what the configuration command gives me before the command make:

user @ hostname $ / KTccminer-cryptonight $ ./configure --with-cuda / usr / local / cuda
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: / usr / local / cuda
checking build system type ... / usr / local / cuda
configure: error: invalid value of canonical build

It seems to me to have found by re-reading the bash-history that it tries to mine with the CPUminer which mine at the same time as ETH and the others algo.
is it possible to mining with CPUs and GPUs with two different software simultaneously without it posing bp?
That is, I use Scott's mining profit switching script and I have activated the plusCPU function of fullZERO in the 1bash

1 / How to install KTccminer correctly?
2 / Is it possible to mine monero with the CPUs in addition to the GPUs ?

@Scott Alfter

The use of your script delighted me, but I hesitated for a long time because of the lack of documentation. I did not know too much or I was going. and I still do not really know where all the files you are using.

Maybe you have some documentation about these scripts?

Greetings, i am in the process of setting up a 13 card rig to see what the world of mining is like. So i have run into an issue that seems odd. I have looked around and have not seen it. So here it is.

My miner keeps telling me it failed to connect to the host and i am not sure why. I am trying to use suprnova.cc pool

I set coin to ZEN
I then changed my worker name to my pool worker name
i have set the address to stratum+tcp://zen.suprnova.cc
i have set the port to 3618
and i have put my wallet address in.

So what am i missing? On my Windows rig i have to put worker name and password info in but i do not see any place to enter that. then when i start it up it just keeps failing to connect to host.

If you just want KTccminer-cryptonight salfter has compiled one :

I finally got around to upgrading to v19 from v17.  I'd had some trouble with v18 and went back to v17, but v19's being much better behaved.  I put my config in (configured to use my MiningPoolHub switcher and Maxximus007's fan-control code) and let her rip.

There is one issue I ran across: no Cryptonight miner.  I noticed it when my mining rig's fans all slowed down.  To get things running again in a hurry, I copied the mining software from my v17 setup.  It's in this tarball:

https://alfter.us/wp/wp-content/uploads/2017/09/KTccminer-cryptonight.tar.xz

Unpack to ~m1. It'll unpack to a Git repo into which you can pull updates (I last updated it just a few days ago) that has already been configured and built.  I might've built it for Pascal (GeForce 10-series) GPUs only; I don't recall for sure if I did, so if you're using older GPUs and it doesn't work for you, you might need to rebuild it.

There was also an upstream change in this miner that requires a change in 3main.  The "-a cryptonight" option is no longer accepted, so load 3main into the editor of your choice, search for "KTccminer-cryptonight" (it's near the beginning of the heredoc that gets written to mph_conf.json), and delete "-a cryptonight" from that line.

Beyond that, the only other changes I made were to set the hostname equal to the worker name (changes in /etc/hostname and /etc/hosts), change the timezone from Eastern to Pacific, and to revise the speed and power figures in the mph_conf.json heredoc with my current configuration (up from 3 GPUs to 4).  As I write this, I'm imaging my v19 setup so I can copy it over to the (physically smaller) stick with v17.

I could compile KTccminer on nv0019, but not on my other ubuntu
gave me some errors
just download the source
and run the commands with no args

Code:

./autogen.sh 
./configure.sh
./build.sh

it should be ok
