Once again, the low-cost heterogeneous cluster shows
an almost linear speedup. The DLB approach is more efficient,
showing an ideal speedup because the communication
traffic is much less compared with the LB approach.
On the other hand, with the high-cost cluster, as observed
in the cluster performance analysis, the DLB approach
becomes more effective with increasing numbers of processes.
The design history is shown in Fig. 4.TS
