Foil 26 Minimize Load Imbalance

From Methodology of Computational Science CPS615 Computational Science -- Spring Semester 2000. by Geoffrey C. Fox
1 But this has a flip side. Suppose we are decomposing Seismic wave problem and all the action is near a particular earthquake fault denoted by .
2 In Top decomposition only the white processor does any work while the other 3 sit idle.
  • Ffficiency 25% due to Load Imbalance
3 In Bottom decomposition all the processors do roughly the same work and so we get good load balance ......
