[ANN] lolMiner-mnx, Mining MinexCoin(MNX) New version: v0.4 (July 22)

[bcfkm]

Hi

I keep getting "Bus error".  I get the same error if I run with all available GPUs or just with a single one.  I have tried all the available options but always get the same error.

Code:

I read through the entire history and see memory mentioned a few times.  Is that related?

Can you point me in the right direction to diagnose whats wrong?

Thanks

@nguyenkhoj93,

1. Remove --platform AUTO
2. Set --device ALLGPU --set-work-batch AUTO --optim OFF                       

Try this?  Good luck!

Pfff - some use Windows because they've much important things to do in their lives than to invest time and energy in learning or using Linux.

This is precisely the lazy, self-entitled attitude I'm talking about. You had a need (linux miner) and refused to meet that need by taking a few hours to set up a linux miner. Thus, you missed out on several weeks, if not months, of mining MNX at much more profitable rates.

This isn't about Windows vs Linux. This is about doing what you need to do to get things done.

I think I am now 100% sure that there is no switch to the primary pool from the fall-back pool not 30 min later, not 10 (which I set in --set-reconnection-timer 10), not at all.

So, I gave it a check and it worked as it should.
What did I do for a try? Well I uses this config:

Code:

--server eu.minexpool.nl,optiminer.eu          
--port 9998,9999                          
--user XQZoBeGPZJoLhTdkcF8bScsNH5Wyesd9g4.W033,XQZoBeGPZJoLhTdkcF8bScsNH5Wyesd9g4.W033      
--pass x,x          
                
--max-connection-attempts 5    
--set-reconnection-timer 10    
               
--set-short-stats-interval 30        
--set-long-stats-interval 120  

So you see I reduced stats output a bit and set the reconnection timer to 10 minutes.

And then got this output:

You see that of cause the first connection to minexpool.nl failed because I configured the wrong port. After 5 attempts it connected to optiminer.eu and started mining. After about 10 minutes it tried to reconnect to minexpool.nl, but failed again (because the port is still not valid) and therefore swaped back to the first failover.

Overall this is exactly what it should do. Test system is an AMD A10 7850K integrated graphics, running Windows 10 Pro.

well, I dont what happens on my system as I dont see it in the log. What I see is that one of my rigs keep on switching from minexpool to surpnova but *never* so far come back. actually both of them switch but randomly. which brings me to the point that it is not even minexpool related

Pfff - some use Windows because they've much important things to do in their lives than to invest time and energy in learning or using Linux.

This isn't about Windows vs Linux. This is about doing what you need to do to get things done.

I actually setup linux on a bunch of usb sticks and ran my rigs with Optiminer for a couple of those more profitable months, but when 4/570s and 4/580s are hashing just as good as my 1080tis I gave up because Optiminer wasn't advancing, it was what it was and it was pretty clear there wasn't any optimizations coming.

When this miner came out I gave it a try and WHAM!, my 1080TIs are going 20k+, more than twice what Optiminer was giving me in Linux.
To me, this just highlighted the need for a more optimized version of the miner for high end cards (I would have run this miner even if it was Linux only), if Optiminer had done it I would probably be running his miner right now, but as I said before, he thought he cornered the market and sat on an unfinished product.

Sure others may have lost out not using Linux early on, but this was a much needed miner and optiminer is the one losing out now because he didn't bother to continue developing his miner.  He could have have made it totally unnecessary for another miner to be developed by optimizing his for high end cards and putting out a Windows miner (as I said, i would be fine without Windows version, but it is easier).

Optiminer opened the door for this project by ignoring the users requests for improvements and a Win version.

now 2 rigs switched to suprnova while minexpool seems ok. how long do I wait until I see them coming back to minexpool? what shall I see in the log?

log info is really bad in this sense

[snovik]

nope. does not switch back. i have to restart miners manually. and connected now

[Lolliedieb]

nope. does not switch back. i have to restart miners manually. and connected now

You you can not see it in the logs - when this happens again and you observe it can you do a full copy of the log and share it with me in private msg? Would like to know what is hoing on there.

By the way: which version & OS you are using?

Optiminer opened the door for this project by ignoring the users requests for improvements and a Win version.

Not really ^^ I started this as a learning project and wanted to see how far I get. The dicision to publish it I took after I saw my approach worked better then I expected - ok I have to admit if there would have been a Windows verson before I would not have done this cross-compiled version.

Anyways I belive having a good miner for all bigger Platforms and GPUs is important for the coin. Leaving an open door for huge large improvements is not a good idea - assume this miner or optiminer would have been developed back 8 month ago but not published but instead used in background. At that time one larger farm easily could have created half the netHash ...

Overall - miners come and go. Mine is not developed to the end yet neither I belive optiminer is. And for sure there will be an other comming some day faster and more mature then ours. Thats crypto - nothing lasts forever / for long here ^^

[UrsaUrsa]

I thought there were no Easter miracles, only Christmas ones but here we go, Optiminer showed up because someone started taking a slice of his cake. I can't wait until Alexis Provos shows up in sp_'s thread telling him off for using his kernels

@Lolliedieb: If I recall it correctly the next step is going to be a patched version (fork!) released by a newbie with 1 post with your dev fee removed. It will definitely leave us guessing who did that... (pg 5, Book of Miner Wars)

I just hope you continue your invaluable work, this has made a lot of nVidia owners extremely happy. Worst comes to worse i'll start donating mnx to you

[ouray]

..., this has made a lot of nVidia owners extremely happy...

I second that!  Thanks Lolliedieb.

[ALFA-Dnepr]

I think that two processor cores do not pull a large number of video cards. Today 6 cards 1060 3 GB were launched and two cards yield 11,000 sol, and four cards total 9700 sol. Loading of processor cores is 40%.
If you run three cards, then we have one -11,500 and two 10500 sol/s.
It is also clear that well-functioning cards have 75-80% of capacity, poorly operating only 65-70% of capacity.
Overclocking parameters are the same.
On a farm where there are four core processors there are no such problems. All the cards give 11400 sol/s. Loading of cores up to 20%

[telemen]

guys, please tell me how many 79xx video card give, I want to connect them for mining?
2 7950 and 1 7970, I will count the coin minex, I seem very promising coin. Thank you for the answer.

[ALFA-Dnepr]

The Neoscript has a similar problem, the CPU  i5 works much better than the celeron / Pentium.
I hope that the programmer Lolliedieb will solve this problem. It is difficult for him to see with 12 cores 

[Timoxa886]

2 7950 and 1 7970, I will count the coin minex, I seem very promising coin. Thank you for the answer.

Hi

7950 - 4500-5000 s/s (Optiminer) 4300-4500 (LoL)
7970 - 7900-8100 s/s (Optiminer) 7500-7900 (LoL)
r9 290 - 10700 s/s (Optiminer)

[tale01]

Optiminer is better than lolminer Hashrate different 1000 sol/s

For fiji at the moment yes, can confirm that is hat problems with lolMiner. I will try to fix it in 0.4.

I user Optiminer, when I increase intensity, GPU use more RAM and speed is up. -> For stock core and reduce core volt get speed 13.2k

In lolminer -> stock core and reduce core volt get speed 12.4k and OC 12.8k
**R9 nano --set-work-batch 7 is the best speed for more or HIGH speed is drop

Hope this information will  improve speed up more than Optiminer

1st of all nice project. there are some problems though. as it uses high memory for amd cards i cannot run the whole rig on mnx. So swtich off the other cards using the config file but it still queries the other cards during startup which causes the system to hang i your mining using another miner. It is a hit and miss. On some system it works fine and wont query the other cards but on some it will despite being selected off. Once running it will leave the other cards alone but on start up it will cause the system to hang.

[toyo87]

Helloo Dev, Is there a video explanation on how to set it up?

I am new to mining and your miner procedure is kind of difficult to be followed up with.

Any assistance from the community will be highly appreciated.

Helloo Dev, Is there a video explanation on how to set it up?

I am new to mining and your miner procedure is kind of difficult to be followed up with.

Any assistance from the community will be highly appreciated.

when you download there would be an example batch file and config file. just edit both to fit your needs. rename the config file if you wish.

[toyo87]

We cannot use your mine if we cannot leave it unatended

I can fully understand that - when you want to make money with mining stability is the alpha and omega. Thats why I released this so early and with hints that this is beta because I do not have the testing machines (yet) to get it rock stable for all platforms that it may support. Therefore I am very thankful about any comment here helping me to improve stability.

I will add an extra mark to the Windows version that it is instable. Linux version currently causes much less problems and should be preferred when possible.

Due to the feedback of last hours, here is the updated list of known issues:

[ALL OS, NVIDIA] High CPU Utilization (Found by me, Confirmed by all NVidia Users here)
Reason:Nvidia has a busy wait for OpenCL kernel completion thats considered a but for over 6 years now, but is not yet fixed (in CUDA it is...)
Problem for Miners: High CPU utilization that may cause problems with CPU cooling. Also dropping hashrate when too many instances are active on the same rig with week CPU and instances may crash. For example an Intel Celeron 3855u may only run one instance of lolMiner currently, Core I5 with 4 physical cores may run up to 3 GPU. More then 4 GPU are currently only stable with Intel Server CPU or AMD Threadripper.
Expected Time to Fix: I am currently testing a fix that will lower the CPU cost of one GTX 1080 from about 115% single core CPU utilization to about 20 (on my testing machine). This will cost about 2% of hash-rate but will allow larger rigs to operate and the CPU to stay cooler. I will provide the beta fix today before 3pm UTC.

Ps: You will always require a strong CPU for Minexcoin anyways, since the found solutions have to be put twice to SHA256 to compare it with the target. This is currently done on CPU and since the high end Nvidia cards can reach up to 20k sol/s this is not easy for the CPU. I expect that when properly fixed the above mentioned Celeron may handle 4-6 GPU but if you have a larger rig it would be better mining an other coin on the other GPUs or have a more potent CPU in the rig.

[ALL OS] At slow / unstable Internet connection sometimes lolMiner still submits shares but server does not accept them (Found by me, Confirmed by an offline friend of mine)
Reason: Well - weak connection is always bad for mining. Often re-connect helps.
Problem for Miners: lolMiner does not detect this yet and thus sometimes computes but shares are not counted. So you can not leave the miner unattended.
Expected Time to Fix: Today. I will add a timer that measures the time difference between last submitted share and the last accepted one. Will cause an automatic re-connect if this time is too large.

[Windows / Official AMD drivers] Miner starts, but reports 0 sol/s or Miner does not start up with CL-compile error (Confirmed by me)
Ps: I am confused... I could be certain that someone yesterday gave a Screenshot of this and reported it but now the post is gone. Why?
Reason: Unknown yet.
Problem for Miners: Can not mine.
Expected Time to Fix: I can reproduce the error (when using CPU part on my Kaveri machine), but do not know why this happens yet. Will require deeper investigation because it seems that the OpenCL code does not return what it should do (and what it does on other platforms...)
 
[Windows, Linux (?) / Official AMD drivers] Miner does not start up with CL-compile error (Found by me, Confirmed by qwep1 and ruckus_pro)
Reason: Some problem with the OpenCL code for some AMD OCL drivers. It is unknown yet if this is also true for Linux version. Linux version with Open Source drivers is stable (but slower)
Problem for Miners: Can not mine.
Expected Time to Fix: I can reproduce the problem on some ages old machine at home. I will have a look into the issue later today and hope to get rid of this within next week.

[Windows] Random crash during execution (Reported by AAile, Confirmed by Aeon_)
Reason I do not know yet. It may be that the Nvidia driver things that the App over-utilizes the card. Currently lolMiner has only a very few things done on CPU before the next iteration starts (because the SHA stuff is done in an other thread), so the pressure on the GPU is very high.
Problem for Miners: The miner can not leave the miner unattended.
Expected Time to Fix: I need more info about when this happens and why. I hope that I can get rid out of this with the CPU load fixes above. Else one countermeasure could be running an external demon that checks if the miner is still running and restart it when it does not. Also I consider inserting a parameter that lowers GPU utilization (but of cause this will cost hash-rate... maybe one finds a stable trade of). I thing at least 2 of this countermeasures will be implemented within next two weeks, hopefully earlier. But for a definite fix I have to find the exact reason first


Ps:
I like transparency and so I report that from current dev-fee income lolMiner-mnx has a market share of 0.8 % (Approx 400 ksols from 49 MSol) and I collected 0.055 mnx as def-fee till now. Thats not that much but more will surely come when the miner gets more stable.  I also wanted to announce that I want to pay back approx half of the income of lolMiner-mnx from its first month of existence to those helping me (be detailed reporting) here getting it stable or test it on different platforms during the first two weeks of existence. Of cause I can not say how much that will be in detail yet, but hey, that offer is better than none
