1 CYCLIC always balances number of elements per processor
  • This balances the computation load if all elements are the same
2 If P (# of processors) divides N (# of elements), BLOCK balances elements per processor
  • There are pathological cases if P < N < P2
3 If P*K divides N, CYCLIC(K) balances elements per processor
