Disclaimer

Updates

• Improve miner work cache to reduce stale block #685

Notes

miner_address.py respects QKC_CONFIG environment variable:

QKC_CONFIG=`pwd`/mainnet/singularity/cluster_config_template.json python3 quarkchain/tools/miner_address.py 1000000000000000000000000000000000000000

Running cluster after modifying config:

# inside the container
python3 quarkchain/cluster/cluster.py --cluster_config <config>
# or
./run_cluster.sh

Instructions for running cluster and mining

For specifying shards in external_miner.py (-s or --shards)

Chain	Shard	Hash Algo	Parameter for external_miner.py
0	0	Ethash	1
1	0	Ethash	65537
2	0	Ethash	131073
3	0	Ethash	196609
4	0	Ethash	262145
5	0	Ethash	327681
6	0	Qkchash	393217
7	0	Qkchash	458753

GPU mining shard ID

Instructions for Ethash GPU mining

ethminer -U http://$CLUSTER_IP:38391 --shard-id $SHARD_ID --cuda-devices $GPU_ID --farm-recheck $TIME

• --shard-id defines one specify shard to mine. shard id 1, 10001, 20001, 30001, 40001, 50001 are Ethash.
• --cuda-devices defines specify GPUs to mine.
• --farm-recheck defines check interval in milliseconds for changed work. For example 500.

Chain	Shard	Hash Algo	Parameter for Ethminer shard ID
0	0	Ethash	1
1	0	Ethash	10001
2	0	Ethash	20001
3	0	Ethash	30001
4	0	Ethash	40001
5	0	Ethash	50001
