I may have a stumbled in a bug.
I have two gpus, with following data:
❯ nvidia-smi --query-gpu=timestamp,name,pstate,utilization.gpu,clocks.sm,clocks.mem,clocks.gr --format=csv
timestamp, name, pstate, utilization.gpu [%], clocks.current.sm [MHz], clocks.current.memory [MHz], clocks.current.graphics [MHz]
2017/07/13 01:45:49.892, GeForce GTX 970, P0, 100 %, 1521 MHz, 3564 MHz, 1521 MHz
2017/07/13 01:45:49.892, GeForce GTX 1060 6GB, P2, 100 %, 1936 MHz, 3802 MHz, 1936 MHz
However while mining all day sometimes gpus crash and I get miner without any hash/s.
I'm running miner with following command:
❯ while sleep 1;do ./miner --server us1-zcash.flypool.org --user <hash>.$(hostname)_gpu --pass x --port 3333 --templimit 75 --tempunits C --api 0.0.0.0:42000 --pec --cuda_devices 0 1 --eexit 3;echo "\n\nDEAD\n\n";sleep 1m;done
and that's output of miner:

and then that keep like that as long I saw the problem (at least 30 minutes).
So I'm thinking why even with --eexit 3 miner didn't restart properly. My solution was to do kill it in another script:
❯ while sleep 10;do curl --silent "http://localhost:42000/getstat" |grep '"speed_sps":0' && (pkill miner && echo "killed" && sleep 5m);done
Who can help me? How I can help improvement of miner
?
Big thx!
