摘要
本文针对以往的并行ＪＯＩＮ负载平衡策略所存在的缺陷，根据并行ＪＯＩＮ负载平衡的特点和要求，提出一个在ＪＯＩＮ操作后期对负载动态调整的算法。通过性能评估说明，该算法具有预处理开销少、灵活的自适应能力、负载平衡效果理想等特点，同时算法简捷、易于实现。
In view of the defects in the previous parallel join load balancing strategy, this paper presents a dynamic load tuning algorithm at the later stage of join operation. The performance analysis inchoates that the proposed algorithm is of less cost in prehandling stage, self-adaptation and ideal load balancing effect. In addition, the algorithm is simple and easy to be implemented.
