So, a bit earlier then I expected but since it is lolMiners birthday (one week old now) lets have a party Smiley

Time for version 0.2
(Also known as: "The first feature release")

As usual here are die Download links:
Linux 64:  Klick Me (v0.2 beta)
Windows 64: Klick Me (v0.2 beta)

Change log:

Added simple watchdog scripts for the miner
Well these aren't really high level software, but for the random crashes this will do the job. On linux restart of crashed miner is almost guarantied with that, for Windows I am not sure about what happens when Windows thinks that miner is hanged up. Lets see. If there are more problems I will pay some of the batch experts here to do a proper watchdog for lolMiner Wink
Please do not leave the miner unattended in the beginning. Due to the long list of modifications I did not test this very deeply...

Added multiple GPU support
Under the hood there were a lot of changes required but here it is: Just add --devices=a,b,c to run lolMiner on your devices a,b and c on the selected platform. As before use --list-devices to see which devices are there on your machine. For each device there will be sol/s displayed separately plus every 60 seconds the average over all cards over the minute. When one GPU does not send any sol/s for about two minutes the miner is closed so it can be cached up by the watchdog for a restart.

Added --set-work-batch switch
This switch will control the load that is send to the GPU at once. The value may be between 1 and 4. For Nvidia GTX 1XXX series I observed that 2 (default) is ideal, while AMD Mainstream graphic may work faster (5 %) having this set to 4. Most extreme example I have seen was some Nvidia Tesla card jumping almost 25% when this is set to 1. So you see: there is no ideal value for all cards out there and it is not much tested yet. But having a switch more is better then no option to choose Wink

Fixed immediate reconnect bug
Some pools had trouble with lolMiner that after an unsuccessful connection attempt it directly tried to reconnect. Now it will wait some time before to give the pool a chance to recover from the problem.

Fixed boost async IO crash
Sometimes it happened that one thread closed the pool connection while an other tried to write on it causing the miner to crash. Now there should be a block taking this exception and print a warning. Afterwards the miner tries to reconnect. Should be more graceful than before.

Fixed invalid share bug
Due to some unclean cleanup of nonce informations the first ordinary mining attempt after  the shares of dev fee were computed was messed up. This did not happen every iteration, but will have cost about 1% profitability on pool side. Pools did not punish sending these faulty shares till now, but will do in future. Now this is fixed and should provide you slightly better income. Alert: Due to this bug which may be serious for some pools I would like to announce that the 0.1x versions are kind of deprecated now. If possible switch to newer version asap.

[Nvidia] Fixed high CPU load after long runtime bug
When lolMiner.mnx ran for a long time (yea indeed that happend) the CPU time it consumes increased. Now lolMiner resets the settings for the --enable-nv-hotfix switch internally. That should help reducing CPU load on a long term. For rigs with many cards it still may be high and it still may be better to run lolMiner-mnx on less cards then are available.

[Windows only:] Switched some of the compiled in libraries
The libraries included in 0.13 were identical (but invisible) to those of 0.11, while the ones in 0.12 were newer. Now in 0.2 the ones fit to those of 0.12 which were more stable for some users. Hope this helps stabilizing the miner in Windows.


-------
And here the current statistics:
Hashrate of all lolMiners out there: ~5.25 Msol/s
Market share: ~ 9,6 %

Till now I collected 8.1 mnx as dev fee, half of this will be spread out as bug bounty.

Also:
Announcement:
At the first monthly birthday of lolMiner-mnx, which is March 12th there will be a new version reducing the dev-fee to 1.5%.
Thank you for the update.
I'd like to try a new miner immediately.

"Readme_windows.txt" remains v. 1.3, but is there planning to add a description?

thx für die neue Version

Wenn ich set "DEVICE=0,1,2" einstelle für meine 3 gpus, wird nur "0" genommen zum minen.
mit dem Befehl lolMiner-mnx.exe --list-devices in einer test.bat zeigt er mir aber alle 3 an, also 0,1,2 Devices

I have 2 x cards but it only pickups up one cards even when I used the following: set "DEVICE=0,1"
Please fix.

Thanks

In Ubuntu if run all the video cards in the same window, the performance drops very much. And the more cards, the lower the productivity of each.

How is your CPU load? Usually each GPU gets its own worker thread that is capsuled of the others.

As for the .bat problem: did you write in a password? When --pass is send to lolMiner the next element is treated as password. If you do "set "PASS=" this kind of kills the --device parameter.

What you can do is figuring out ideal commandline to run the miner without the .bat and then copy over the whole string to bat... that will also work Smiley

GPU load is only 10-15%


run_miner.sh file:

#!/bin/bash
POOL=mnx.suprnova.cc
PORT=7077
USER=andreassantonio.Andreassant3
PASSWORD=1
PLATFORM=0
DEVICE=0,1,2,3,4,5

cd "$(dirname "$0")"
while true
do
  ./lolMiner-mnx --server mnx.suprnova.cc --port 7077 --user andreassantonio.Andreassant3 --pass 1 --platform 0 --device DEVICE=0,1,2,3,4,5 $HOTFIX $@
  if [ $? -eq 134 ]
  then
    break
  fi
done

If start miner for each GPU - all work good.

for me too
2x1070+2x1060 = speed like 1x1070
and segmentation fault

GPU load is only 10-15%

But I asked for CPU not GPU ^^

Better try that way:
Code:
#!/bin/bash
POOL=mnx.suprnova.cc
PORT=7077
USER=andreassantonio.Andreassant3
PASSWORD=1
PLATFORM=0
DEVICE=0,1,2,3,4,5

cd "$(dirname "$0")"
while true
do
  ./lolMiner-mnx --server mnx.suprnova.cc --port 7077 --user andreassantonio.Andreassant3 --pass 1 --platform 0 --device 0,1,2,3,4,5 $@
  if [ $? -eq 134 ]
  then
    break
  fi
done

By the way: you did not use the hotfix ... you are running on AMD? Then I would recommend to use optiminer, that one is faster for AMD right now. For Nvidia you should add the --enable_nv_hotfix, because else it is likely that 6 GPUs will cause a lot of load and a segmentation fault - unless you have some Ryzen Threadripper or Intel equivalent in that system.

for me too
2x1070+2x1060 = speed like 1x1070
and segmentation fault

Can you show how you start the miner and what is the output of lolMiner-mnx --list-devices?

It' s my error, CPU load 10-15%. Not amd, my system: i7 7700 + gtx1060x6.

Hi all out there having problems with passwords or multi-GPU in Windows ... Unfortunately I included some broken .bat file where I confuse PASS and PASSWORD...
so here is how it should look like:

Code:
@echo off

setlocal enableDelayedExpansion

Rem #################################
Rem ## Begin of user-editable part ##
Rem #################################

Rem Insert your pool name here
set "POOL=eu.minexpool.nl"
Rem Insert your pool port here
set "PORT=9999
Rem Insert your user and worker names here
set "USER=XQZoBeGPZJoLhTdkcF8bScsNH5Wyesd9g4.worker0" 
Rem Insert your worker password here
set "PASS=x"

Rem Insert the index of the platform you want to run on. Run lolMiner-mnx.exe --list-devices
Rem to see all available platforms and the available devices for each platform
set "PLATFORM=0"
Rem Insert your devices to run the miner here. For multiple GPU pass a comma separated list, e.g.: 0,1 for using two GPUs
set "DEVICE=0"
Rem Uncommend the next line (by removing Rem) to enable the Nvidia CPU load fix
Rem set "HOTFIX=--enable-nv-hotfix"   

Rem #################################
Rem ##  End of user-editable part  ##
Rem #################################


set "PARAMS=--server %POOL% --port %PORT% --user %USER% --pass %PASS% --device %DEVICE% --platform %PLATFORM% %HOTFIX%"

:MINE
Start /wait /high lolMiner-mnx.exe !PARAMS!
goto :MINE

Unfortunately this version runs like a 3 legged elephant on my 7x 1070 rig. Previous version, I can comfortably run two instances, getting around 12ksol on each card. This one gets me 7ksol at the beginning but frequently drops to lows of 500sols... I played around work batch, etc... nothing really helped. Back to v11 now. I hope you come up with a fix for multi gpu. Cheers!

Thanks changing PASSWORD to PASS fixed the issue where only device 0 was being used.


1 x 1070 on Windows 10 with V0.2 does 14000 sols
2 x 1070 on Windows 10 with v0.2 only does 7000 sols per card

I also tried enabling the Nvidia fix but it did not make any difference.


Good work sofar lolliedieb!

The Miner is closing and opening every 1-2 Sec....
Doesnt work for me, not with 2 gpus, and not with 3 gpus.. closing/opening loop from the Miner
But Its finding all 3 devices right

Der Miner schließt sich jede Sekunde bis 2 und öffnet sich wieder und zack direkt wieder zu, wieder auf usw...endlos Sad
Er zeigt aber alle 3 Gpus richtig an

0.2 version has increased sols for RX560 from 2600S/s to 3200S/s, but it's still low vs optiminer (5000S/s)

It is good to see that you put a lot of efforts in this project, it is good to have a good miner for this algo under windows, but not so much for MNX, there is not a lot of sense because Optiminer is way better then this(I understand it is still in early development), but please consider that MNX will change algo later this year.

Performance with this miner for nvidia pascal is very good: now nvidia cards with this miner perform at similar level or even better than equivalent amd ones with optiminer.

I hope you will add zerocoin equihash version too ...

Tested ver. 0.2 on linux, g4400 cpu, 6x 1070ti. Started the miner with 6x gpus. Hashrate was around 5k per card (ver. 0.13 13k per card), dropped to 2k sols per card, then dropped to 2 sols per card and then the rig restarted. Will try with different number of gpus tomorrow. Using hotfix did nothing, still low hashrate and rig restarts.
