I'm all the way game with optimizing any codes
I think the best approach on optimizing temp or other codes is whomever write, test and optimized it, send it to fullzero and other devs to optimize other codes with it before releasing new version with it

We can use "if elif else fi " to stop the code from reading next conditions, right?

It's already included since 19-1.3, look for "zm or ewbf" in 1bash
Here is easy way to update it

Update dstm zm miner easy way

agreed, this code seems redundant... I haven't fully analyzed 3main but the only logic behind it is to stop code below it to execute if the condition was met.

we need to clean and optimize the current code before adding any more features which will make the code even messier than it is now.

while we are on the programming topic... I really can't stand the misuse of logs to pass information/variables between the scripts. not only that the logs slow down everything, they are killing the usb sticks, causing all kinds of problems, hangs, freezes, etc. and i see more and more people are recomanding usage of screenlog

how about using named pipes (fifo) to pass info between the scripts. nothing is saved/logged by using a named pipe and it is much faster. leave the logs for what they were really ment to: to record problems

example: we want to get the fan speed and temps from the temp control so we can send it trough telegram. the easy solution is to write all those values from the temp control script into a log, then read from the log and send telegram. the problem is that in order to satisfy the telegram, the temp script has to write line by line that info for each gpu into a log, 24/7 so that the info is there when telegram needs it.

if we rewrite the temp control to keep sending all that info to a named pipe, the info will be there when telegram needs it without writing to a log over and over, 24/7, and write to a log only critical info/errors that would be needed for troubleshooting

i started rewriting the temp control and i intend to incorporate the named pipes but that will break compatibility with telegrams, web stats, and whatever else is fetching the info from logs. i just can't find enough free time to rewrite all the scripts in nvoc

if interested in the development and optimization of nvoc, please google "bash named pipe" and research then share your thoughts, maybe we can split the workload if you are interested

Are there plans to add dstm equihash miner?

It bumped my 1070 TI's up 50 sols making them hash at 4.7 sols per watt O_o

yup, i wish i had little bit more time to dedicate to this too

btw, regarding the bitcoin=theground... I posted solution how to rewrite it on discord right after you asked in the same subchannel, i beleive it was the oc channel, about two days ago...

if you can't find it, just replace all instances of this:


with this:


or, depending on your style, with one-liner

I've mentioned this problem a while ago... incorporated quick and dirty patch on my rigs to fix it and wanted to rewrite the watchdog... it is still on my TODO list...

Your solution is also not the best one but it helps... that code is there to detect semi-freeze, when some card is acting up, however, as you noticed it is not well written and in some cases it takes hours before it reacts. On few ocasions I had one card freezing, pulling whole rig to a crawl... on 13 GPU rig it took about 3-4 hours for watchdog to realize that it was time to restart... sigh...  a quick patch was to lower the counter as well... I'll jump to it once I finish rewriting the temp control.

Thanks a lot mate.
It was always a question for me what those loops are for...
Tested the miner start script without the loops and all is good.

I think as you said its some legacy code from old nvOC and can be removed.

And as I said before that wtm-miner is just a copy of 3main miner starts so wtm auto switch dont restart 3main which will take so long and just switch miner.

I hate quoting myself, but here goes. I did a simple test to see if the infinite loop is necessary given the screen command. Try this for yourself:


will launch top in a screen. Then exit the ssh session and login again. You can then resume the top session with the usual screen -r top. So, I don't think that infinite loop in 3main is needed any longer. However, I have not exercised all parts of nvOC but I can tell you for certain that it is not needed after those miners who are launched with screen.

Hope this helps.

I ran it through beautify and read it. It is basically a stripped down version of 3main. I don't know what your expectations are as far as it exiting, but this code block (same as in 3main) is meant to just run forever:


So scripts like this and 3main are meant to not "fall out". I am not overly familiar with the screen command but it would appear that the parent process of them is not 3main or as in your case wtm-miner, but rather "/sbin/upstart --user". As such, I am not sure if this infinite loop is required any longer. It may be legacy code before screen was implemented. Give it a go without it in your script and see if the miner continues to run.

Hope this helps.

Set your coin to this

Make sure you have added your BTC_ADDRESS at necessary places. If you are not sure, search for 'BTC_ADDRESS' in 1bash, some where in the middle you will see this

Add your BTC address there, that should do the trick.

Regarding 1.4 version, you can't update to 1.4 using 4update or other commands, you need to do a fresh install (new flash)

EDIT : About 1.4 version

Extract the zip, take another memory stick/ssd write that image using HDDRAW (what ever you have used to write the image before)and plug and play.

My other suggestion for faster miner restart is to separate miner start lines from 3main, so wdog only start miner and not 3main

Yep, good call mate, i agree there were so many other corner cases still missing, like @leenoox saying we need to go through most parts of our code and re write it, it wasn't the best but it does the job more or less, it has reached that point with the help of our early contributors. Every one occupied with so many things, even though we want to spend time on those things, we only have 24 hours a day and we have a life too, not easy to spend time, but we can do bit by bit like 20-30 mins once in a while (even weekly works) and improve it together, join those pieces together.

Commit for nothing, deliver something as something is always better than nothing.

I think it would be nice to gather all these points and improve it step by step, @leenoox you also suggested some change in the code where "bitcoin = the ground" stuff like that, that has been lost some where in chat. Any such things please PM me here or on Discord, I will put everything on discord in 'to_do' locked channel (not putting it open because of lots of messages!!) , or any other place, suggestions are welcome.

Thanks everyone.

Sorry if you want a laff read on, many dumb questions will follow.
how to I get the nicehash profit switching to work?
I think I am using an earlier version of ncOC, Im not sure which one but it wont update, and for sure its not v0019-1.4.
This is the top part of 1bash

Ive downloaded v0019-1.4, but how do I go about installing it? Is it just a case of unpacking it in the home directory?

Can I ask what this line is for ?



Update:
Got it after add your edits,
Thanks a lot for edit

Thanks mate
Can you please have a look at the ~/z_papampi_versions/wtm-miner
and see why it wont exit when done?
I tried with done, exit, exit 0, .... and it stays running in the background

papampi:

I don't have a wtm-miner. That is another reason that I beautify any scripts my miners run with beautify_bash.py. Mismatches like that are trivial to find with the proper indentation. As for the mod I did, here is more of it:


With this in place, an 8 GPU rig miner restart by the watchdog is reduced from 8 minutes to ~ 10 seconds.

Amazing idea,
What I was testing is to just restart miner instead of restart 3main which will take 2-3 minutes, by using a separate miner start file which I use for WTM switcher
You can check it in ~/z_papampi_versions/wtm-miner
It has the 3main miner startup lines ( without salfter, zpool, mph) and I use that instead of restarting 3main

instead of :

I use :


Can you please tell me where you add your edit?
I made so many edits that line 98 doesnt look like the correct place


Update: I think that wtm-miner included in 1.4 is missing a done or exit at the end.

Watchdog Improvement?

I have been reading over the watchdog script and seen what I think is an opportunity for improvement. The current logic loops every 10 seconds and looks for GPU utilization below a threshold (90%), if it finds this, it begins incrementing one counter (JEEP) and decrementing another (COUNTER,  initially set to 6*#GPU) for each occurrence [per GPU]. My issue is that the current logic has to wait 6*#GPU*10 seconds, or a minute per GPU before it will attempt a miner restart.

My thinking is why not just check for the existence of a miner process - if none is found, we can just skip the rest if the countdown and get right to attempting to restart the miner. This can save many minutes of lost mining time. The downside is that it is so much faster than the existing that if you do have a configuration issue, it will be launching miners and rebooting at a much faster rate. So, maybe this is more of an expert mod.

Anyway, I have been running a modified version of IAmNotAJeep_and_Maxximus007_WATCHDOG that has this additional logic and it work great for ME. In the existing 19-1.4 version of the script, starting at line 98, I added this:


By setting COUNT=0 for the "no miner found" condition, I am effectively removing the delay in decrementing COUNTER all of the way down before the script takes action.

Thoughts?

How on earth i missed that point 

I only saw NVIDIA from this line; "Fully support AMD and NVIDIA OpenCL devices".

Thanks @leenoox

I've never understood why in this query every GPU shows the total number of GPUs instead of just the number of GPUs.!!!
