Hadoop Çatısının Bulut Ortamında Gerçeklenmesi Ve Terabyte Sort Deneyleri

open access: yesMANAS: Journal of Engineering, 2015
Hadoop framework employs MapReduce programming paradigm to process big data by distributing data across a cluster and aggregating. MapReduce is one of the methods used to process big data hosted on large clusters.

A privacy-preserving parallel and homomorphic encryption scheme

open access: yesOpen Physics, 2017
In order to protect data privacy whilst allowing efficient access to data in multi-nodes cloud environments, a parallel homomorphic encryption (PHE) scheme is proposed based on the additive homomorphism of the Paillier encryption algorithm. In this paper

MASSIVE SIMULATIONS USING MAPREDUCE MODEL

open access: yesInformatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2015
In the last few years cloud computing is growing as a dominant solution for large scale numerical problems. It is based on MapReduce programming model, which provides high scalability and flexibility, but also optimizes costs of computing infrastructure.

MapReduce SVM Game

open access: yesProcedia Computer Science, 2015
AbstractDespite technological advances making computing devices faster, smaller, and more prevalent in today's age, data generation and collection has outpaced data processing capabilities. Simply having more compute platforms does not provide a means of addressing challenging problems in the big data era.

Research on the analysis and statistic of geographical conditions based on the strategy of "Grid Index + MapReduce"(“格网索引+ MapReduce”策略下的地理国情统计分析研究)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2017
地理国情统计分析是深度研究地理国情普查数据的首要前提.针对现有单机集中式数据存储与处理方式存在耗时长、效率低甚至不支持的问题,设计了“格网索引+MapReduce”策略,基于规则格网设计普查数据文件的分块组织与分布式存储方式,研制了格网索引与空间分析相结合的双层过滤机制,构建基于MapReduce的地理国情并行统计算法.最后,与无索引MapReduce、ArcGIS平台进行性能对比测试,结果表明:“格网索引+ MapReduce”方法的统计效率远高于ArcGIS平台 ...
