Reducing Synchronization Delay

• A goal when you are partitioning a network across nodes is to make the lookahead between any pair of nodes large.
• PGENESIS provides the setlookahead command for you to inform it of the lookahead between nodes:
  • setlookahead 0.01 // sets lookahead to 10 mS
  • setlookahead 3 0.01 // sets lookahead to 10 mS w.r.t. node 3
• The getlookahead command reports the current setting with respect to a particular node, and the showlookahead command reports the minimum lookahead to all other nodes:
  • getlookahead 3 // gets lookahead with respect to node 3
  • showlookahead // get lookahead with respect to all nodes
