Have you set cpu mining to off ?
yep, for sure
looks like 3main select only one GPU for a reason I don't know
this is due to a problem with the 3main implementation wi$em@n found; but I haven't fixed yet. You can do this manually for now by finding this area in 3main:
if [ $COIN == "XMR" ]
then
HCD='/home/m1/xmr/stakGPU/bin/xmr-stak-nvidia'
ADDR="$XMR_ADDRESS.$XMR_WORKER"
cat </home/m1/xmr/stakGPU/bin/config.txt
"gpu_threads_conf" : [
{ "index" : 0,
"threads" : 32, "blocks" : 18,
"bfactor" : 8, "bsleep" : 10,
"affine_to_cpu" : false,
},
],
"use_tls" : false,
"tls_secure_algo" : true,
"tls_fingerprint" : "",
"pool_address" : "$XMR_POOL",
"wallet_address" : "$ADDR",
"pool_password" : "x",
"call_timeout" : 10,
"retry_time" : 10,
"giveup_limit" : 0,
"verbose_level" : 4,
"h_print_time" : 60,
"output_file" : "",
"httpd_port" : 0,
"prefer_ipv4" : true
EOF
cd /home/m1/xmr/stakGPU/bin
screen -dmS miner $HCD
if [ $LOCALorREMOTE == "LOCAL" ]
then
screen -r miner
fi
and adding an additional:
gpu_threads_conf" : [
{ "index" : 0,
"threads" : 32, "blocks" : 18,
"bfactor" : 8, "bsleep" : 10,
"affine_to_cpu" : false,
},
{ "index" : 1,
"threads" : 32, "blocks" : 18,
"bfactor" : 8, "bsleep" : 10,
"affine_to_cpu" : false,
},
{ "index" : 2,
"threads" : 32, "blocks" : 18,
"bfactor" : 8, "bsleep" : 10,
"affine_to_cpu" : false,
},
{ "index" : 3,
"threads" : 32, "blocks" : 18,
"bfactor" : 8, "bsleep" : 10,
"affine_to_cpu" : false,
},
],
index block per GPU to the "gpu_threads_conf"
as the above would be for 4x gpus.
