# UPDATE GLM NODE PRICES
# GLM node not getting tasks and not earning you anything? No problem!
# This script checks the median of the prices on the golem.network and updates all 3 values related to price:
# - price for CPU per hour
# - price for working environment per hour
# - price for starting a task
# It also checks what percent of the nodes are actually doing work and assigns that much percent to the median price.
# Expected result: GLM nodes will get more and more taks, because your price is OK compared what other providers do.
# Feel free to run a chmod +x on it and run on an hourly basis with cron. This way your nodes get more tasks.
# In your crontab for your user running golemsp add the command
# @hourly /path/to/auto_update_GLM_node_prices.sh
