Ethminer: Featurerequest: Restart Miner on 0 MH/s

[faithless1108]

Hey Devteam,

first of all: Thank you for your great work. Ethminer ist running verry fast an stable on Nvidia-Cards now. We're running a 6x GTX 1070 rig @arround 190mh/s! Way better than Claymore!

But theres one feature wich would be verry nice. Sometimes (didn't find a reason yet) the Miner has "CUDA unspecific launch fail" and puts out 0 MH/s, for hours if you dont stop and restart it.

It would be verry nice if you could start Monitoring this issue and just restart the Miner if something like this happens...

They are some scripts around to deal with that.
Here a tool I'm doing: https://github.com/orkblutt/MinerLamp

[Gertsch]

Have got the same issue occurring from time to time on a small 2x1060 rig.
Can't tell why, but it would be nice to have such an option.

[derubm]

another watchdog:
reacts on exception, error in output, restarts mining process.
multible pools configurable- no GUI, only dos box ;)
https://github.com/derubm/Ethminer_Watchdog
if you guys like a gui, orkblutts tools is nice.

If we get an API on that program, monitoring the hashrate and restarting the miner will be easy.
See issue #170

Ethminer_Watchdog does not work on us2.ethermine.org:14444 ?
I can not make it work

[derubm]

if its a stratum you need to correct -F to -S in mining.cmd

2nd solution: use stratum proxy (that is the way i personally run my miner)
https://ethermine.org/ << scroll down to stratum proxy by dwarfpool

[Git1Hub2]

Error:
Stratum Connecting to the stratum server http://us2.ethermine.org:14444/ ...... / GTX1060/[email protected]
Stratum solves: The specific class has not been hidden
Stratum Reconnecting in 3 seconds ....

[derubm]

config string according to ethermine would be;
us1.ethermine.org:4444 -O Your_Ethereum_Address.RigName

anyway easiest way is to use stratum proxy,. ( https://github.com/Atrides/eth-proxy/releases )
pre configured local stratum mining is allready as a sample in watchdog.bat ( entry 2. )
needs change on miner and password for your configuration.

[Git1Hub2]

Changing only (Your_Ethereum_Address.RigName)
GTX 1060 3G = 29MH / S stable
very good
congratulations

[jimmykl]

@Git1Hub2 29Mh/s on a 1060 3G?! What type of card, memory and overclock?!

[Git1Hub2]

Is it right?

[jimmykl]

Oh yep that's a good result!

[Git1Hub2]

Sorry but it's not mining!Nothing appears in the pool

[derubm]

your mining url is false
(address. ???)
can you post me the line that you use ?
it should be (replace address, miner name , email)
http://eth-eu.dwarfpool.com:80/0x762c924a469f21a446529bd8f6b07db6bde124bf/Rigname/[email protected]
(no point after your address, but a slash, then you miners name)
edit: on dwarfpool aprox. 10-15 minutes after first submitted share you should be able to see your miner working.

Why is the MH / s so high? I already tried a lot and I can not change ... I'm a beginner in this rsrs sorry

[derubm]

its because of your memory speed, it is maxed out.
for questions like that join IRC freenode chan #ethereum-mining. this should not become a message board here.

@Git1Hub2
May I ask how did you installed tesla driver (ver. 376.51) in your 1060? i tried it but failed miserably...

[Git1Hub2]

I downloaded the cuda_8.0.61_win10 from 1.3gb
And he installs this driver (376.51) alone

I encountered the same issue while playing around with different clock-speeds, power and maximum wattage and wrote a little script to restart on low watts (low MHz sounds even better ...):

#!/bin/bash

wallet_id="0x2824194fa61ac4b64ffa485b10d1045c9fbc83d3"
pool_url="http://eth-eu.dwarfpool.com:80/"
etherminer_cmd="ethminer -U -F $pool_url/$wallet_id --farm-recheck 200"
min_watts="55.00"

echo "Starting miner"
eval $etherminer_cmd &
echo "Waiting for 30s for watts to rise"
sleep 30

while sleep 10;do
    current_watts=$(nvidia-smi -i 0 --format=csv --query-gpu=power.draw | sed -n 2p | cut -d ' ' -f 1);
    echo "Current watts: $current_watts";
    if (( $(awk 'BEGIN {print ("'$current_watts'" <= "'$min_watts'")}') )); then
        echo "Restarting, because low on current watts: $current_watts <= min_watts"
        killall "ethminer"
        sleep 5
        eval $etherminer_cmd &
        echo "Waiting for 30s for watts to rise"
        sleep 30
    fi
done

[DeadManWalkingTO]

I believe now the issue have been solved #757 (added --exit parameter to exit whenever an error occurred).

[smurfy]

Its not solved, but a workaround exists now.

[sandrodz]

@smurfy what is the workaround?
