摘要：This study focuses on the scientific data processing and transmission in map tasks. Based on Hadoop MapReduce of cloud computing, we propose the basic idea of scientific data prefetching mechanism proposed in this paper is to overlap the data transmission process with the scientific data processing process. And we propose the detailed procedure of scientific data processing algorithm which can improve the overall performance under the shared environment while retaining compatibility with the native Hadoop MapReduce in this study. ? 2013 Asian Network for Scientific Information.
