It consists of items that are valid for a scheduling cycle and is used for message passing across predicates and priorities. Some examples which could be used as fields are number of volumes being used on node, current utilization on node etc. IMPORTANT NOTE: Make sure that each field in this structure is documented along with usage. Expand this structure only when absolutely needed as this data structure will be created and destroyed during every scheduling cycle.
