2	Computing edge values requires edge list and node values Distribute edges Þ parallel, no communication for edges Replicate edges Þ sequential or broadcast edge values Distribute nodes Þ move ³shared² endpoints Replicate nodes Þ no movement for endpoints
3	Updating node values requires edge list, edge values, and node values Distribute edges Þ parallel, no communication for edges Replicate edges Þ sequential, no communication for edges Distribute nodes Þ move ³shared² endpoints Replicate nodes Þ move all endpoints
