Tasks are categorized into small and large tasks based on watts requirements.
All the large tasks are packed into offers from agents belonging to power classes A and B, using Bin-Packing.
All the small tasks are spread among offers from agents belonging to power class C and D, using First-Fit.
BinPacking has the most effect when co-scheduling of tasks is increased. Large tasks typically utilize more resources and hence,
co-scheduling them has a great impact on the total power utilization.
