Power-Efficient Load-Balancing on Heterogeneous Computing Platforms

In order to address the throughput constraints of the system at minimal power consumption, the workload of computing nodes should be balanced. This requires accounting for the underlying hardware characteristics and throughput sustainable by these nodes. This work provides a workload distribution and balancing methodology of a divisible load under a throughput constraint, on heterogeneous nodes. The power efficiency of each node is considered during load distribution. For load balancing, the frequency of the node is determined which just fulfills the timing requirement. Compared to a state-of-the-art-scheme, our scheme results in up to 64% performance improvement for the benchmarks evaluated in this paper.
