# GREEN configuration:
##################################
# Turn on "green" policy. (This is the policy that enables green computing).
# Here we are doing it for all nodes, but it can be controlled on a node-by-node basis
# Default is STATIC, which means green computing is disabled.
#NODECFG[DEFAULT]  POWERPOLICY=STATIC
NODECFG[DEFAULT]  POWERPOLICY=OnDemand

# Configure the power provisioning and power state query scripts for the power
# management system.
# Note that this is an entirely different RM (with a name of power in this case 
# and a type of 'PROV').
# The PROV type RM is the only one that uses a NODEPOWERURL.  Additionally, the 
# output of the CLUSTERQUERYURL for this type of RM is different.  (See docs)

# We want green policy to work so it allocates jobs to compute nodes already
# powered on and will power on powered-off compute nodes only when there are
# no powered-on compute nodes available. This requires using the PRIORITY 
# node allocation policy with a PRIORITYF function that has the POWER variable
# as the greatest contributing factor to the function (1 = powered-on,
# 0 = powered-off).
# If we want all compute nodes to operate under green policy, we can assign
# the PRIORITYF function to the default node configuration, which is easier
# than assigning it to individual compute nodes. If only some compute nodes
# should operate under green policy, then the PRIORITYF function must be
# configured for the individual nodes. Note the POWER variable must be the 
# largest factor in the function below; it is assigned the largest multiplier,
# which should be greater than the sum of all other factors! Doing so forces
# Moab to use all eligible powered-on nodes for workload placement before
# powering on any eligible powered-off nodes.

# Enable PRIORITYF functionality
NODEALLOCATIONPOLICY  PRIORITY

# Use a priority function that uses power as the major factor (plus some other imaginary factors)
#NODECFG[DEFAULT]      PRIORITYF='1000000*POWER + 1000*factor2 + 100*factor3...'
# Use a priority function where power is the only factor.
#NODECFG[DEFAULT]      PRIORITYF='10000*POWER'
# Use a priority function that adds some randomness but uses power as the major factor.
NODECFG[DEFAULT]      PRIORITYF='10000*POWER + 10*RANDOM'

# Set a priority function that specifies the order nodes should be chosen to power 
# up/down. By default, Moab will start at the top of the node list and go down. Some
# installations want to rotate power cycles among nodes in a different order.
# The configuration below forces Moab to power on/off random nodes, which 
# eventually guarantees all nodes occasionally go through a power cycle.
#GREENPOOLPRIORITYF '10*RANDOM'

# Ensure we are recording power management events
# (powering on and off nodes are recorded as "node modification" events).
#RECORDEVENTLIST +NODEMODIFY

# Set the size of the standby pool. This is the number of idle nodes that will
# be powered on and idle. As the workload changes, Moab turns nodes on 
# or off to try to meet this goal.
# Default value is 0
MAXGREENSTANDBYPOOLSIZE 5

# Set the length of time that it takes to power a node on/off. This will be the 
# walltime of the system job that performs the power operation and should be the
# maximum expected time. If Moab detects (via the power RM) that the power
# operations have all completed, the system job will finish early.
# Default value is 10 minutes (600)
PARCFG[ALL]       NODEPOWEROFFDURATION=600
PARCFG[ALL]       NODEPOWERONDURATION=600
# Set the length of time a node should remain idle before it is powered off.
# This prevents Moab from immediately powering off nodes that have just finished 
# a job. Increasing this number should decrease power on/off thrashing
# This should be set higher than NODEPOWEROFFDURATION and/or NODEPOWERONDURATION
 NODEIDLEPOWERTHRESHOLD 660

# If a node fails to power on, we need to remove it from the available nodes so
# Moab won't keep [re-]trying to power it on. Do this by setting a reservation 
# on the failed node to give time for manual investigation.
