Among unaggregated points, see if we can make a reasonable size aggregate out of it.
Among unaggregated points, see if we can make a reasonable size aggregate out of it. We do this by looking at neighbors and seeing how many are unaggregated and on my processor. Loosely, base the number of new aggregates created on the percentage of unaggregated nodes.
Parameter | Meaning |
---|---|
aggregation: min agg size | minimum number of nodes which have to be in an aggregate. |
aggregation: max agg size | maximum allowed number of nodes in an aggregate |
Only nodes with state READY are changed to AGGREGATED.
