What logic does Smarts use to create partitions?



If a system has no neighboring systems, then it is not put into any partitions. To create a partition, two systems must be neighbors of each other. To calculate a partition, Smarts uses BFS (Breadth First Search) traversal of graph, starting with #sysObj#. For example, if System A appears as the neighbor of System B, and System B appears as the neighbor of System A  then Smarts will create the partition with these two systems as members.  A system can not be in more than one Partition.
