Cluster-based computing, which exploits the aggregate power of a netwo
rk of workstations, has drawn increasing attention from the parallel p
rocessing community. The main problem with this computing environment
is the permanently changing workload of individual workstations which
makes the efficiency and the execution time of parallel applications u
npredictable. In this paper, we introduce an efficient load balancing
scheme which aims at dynamically balancing the workload of data parall
el applications in this computing environment. Simulation and experime
ntal studies of our load balancing strategy are performed under variou
s load situations and it is shown that it can effectively balance the
workload among the workstations involved. Further, it was shown that a
significant improvement in computing performance can be achieved when
using our load balancing strategy as compared to the case where no lo
ad balancing is applied, particularly under a heavily loaded system.
