分析同构集群中的并行计算熵,验算并行计算熵对负载均衡程度的影响.研究结果表明,同构集群的最大相对负载率随着并行计算熵的递增而递减,当且仅当负载完全均衡时,并行计算熵达到最大值.并行计算熵能较好地衡量同构集群的负载均衡程度,可有效提高同构集群的性能.
Parallel computing entropy in homogeneous cluster was studied.Theoretical analysis shows that maximal relative load ratio tends to decrease when parallel computing entropy increases.Parallel computing entropy is maximized if and only if load is completely balanced in homogeneous cluster.The load balance degree is able to be measured well by parallel computing entropy,which can be used to improve the performance of homogeneous cluster.
