Performance analysis with and without dynamic rebalancing. Time line profile for all the PEs (rows) on a SMP process for the 16K cores run. White shows idle time and colored bars indicate busy time. Dynamic rebalancing eliminates trailing idle time resulting in better utilization. The total time per step reduces from 9.8 seconds to 8.5 seconds.
