------------------------------------
Summary: Make item cost calculation consistent in GD BSP
Key: HAMA-660
URL: https://issues.apache.org/jira/browse/HAMA-660
Project: Hama
Issue Type: Improvement
Affects Versions: 0.5.0
Reporter: Tommaso Teofili
Fix For: 0.6.0
Cost per item is calculated without knowing the total number of items which is
ok from an efficiency point of view but makes plugging of new cost functions
bug prone since the total cost is then always divided by the number of items.
It'd be good to have a 0th superstep where total number of items is read and
then it's used in CostFunction#calculateCostPerItem
