# Sample Server Configuration File for Grin
#
# When running the grin executable without specifying any command line
# arguments, it will look for this file in three places, in the following
# order:
#
# -The working directory
# -The directory in which the executable resides
# -[user home]/.grin
#

### SERVER CONFIGURATION              ###
#########################################

[server]

#is stored

#If seeding_type = List, the list of peers to connect to.

#The chain type, which defines the genesis block and the set of cuckoo
#parameters used for mining. Can be:
#AutomatedTesting - For CI builds and instant blockchain creation
#UserTesting - For regular user testing (cuckoo 16)
#Testnet1 - Full production cuckoo parameter (cuckoo 30)
#

#has multiple GPUs, or if you want to mine using multiple plugins

### CUCKOO MINER PLUGIN CONFIGURATION ###
#########################################

# These entries configure instances of cuckoo miner
# plugins if the 'use_cuckoo_miner' value above is
# set to 'true'.
#
# Multiple plugins can be specified, (e.g. a cpu
# miner and a gpu miner running in parallel). However,
# if 'use_async_mode' above is set to 'false', only
# the first plugin specified will be used for mining
# in single-threaded mode

# You'll likely get the best performance using a
# single GPU and single CPU plugin in parallel

#The fastest cpu algorithm, but consumes the most memory
#Also requires instructions that aren't available on
#older processors. In this case, use mean_compat_cpu
#instead
#[[mining.cuckoo_miner_plugin_config]]
#type_filter = "mean_cpu"
#parameter_list = {NUM_THREADS=4, NUM_TRIMS=68}

#Same as above, but for older processors. Will be slightly
#slower.
[[mining.cuckoo_miner_plugin_config]]
type_filter = "mean_compat_cpu"
parameter_list = {NUM_THREADS=1, NUM_TRIMS=68}

#note lean_cpu currently has a bug which prevents it from
#working with threads > 1

#[[mining.cuckoo_miner_plugin_config]]
#type_filter = "lean_cpu"
#parameter_list = {NUM_THREADS=1, NUM_TRIMS=7}

#CUDA verion of lean miner
#Can currently be used only in Production (30) Mode
#This plugin is not built by default. To build:
#1) Ensure the latest cuda toolkit is installed
#   (nvcc should be in your PATH)
#2) Uncomment the 'build-cuda-plugin' feature
#   in pow/Cargo.toml
