| 摘 要： | 全文检索是一种资源消耗型操作,并行全文检索可以缩短全文检索的响应时间,以前的并行检索研究主要集中在磁盘资源和ＣＰＵ资源的优化利用方面,本文提出一种采用合作缓存技术的并行全文检索模型,以优化对内存资源的利用,并对该模型进行了分析和评价,说明该模型可以有效地提高检索性能。

| Abstract: | Fulltext Retrieval is a kind of resource eager operation. Parallel fulltext retrieval technique can improve the performance of response time. However, researches on parallel fulltext retrieval before only focus on the optimization of disk and CPU. This paper presented a parallel fulltext retrieval model using cooperative caching to get benefit from optimization of memory resource. By analyzing the result of simulation, we demonstrates that this model can effectively improve the performance of fulltext retrieval. |
