摘要
Abstract
Lots of data are produced by large scale scientific facilities in High Energy Physics(HEP)studies. Scientific computing is based on these distributed data. Grid computing technology is used to share data between different sites in traditional way. However, low resource utilization, long response time and difficult operations limit data sharing between small sites. While a cross-domain file system based on streaming&cache is designed for data sharing between small sites in HEP computing. Native access for remote data, quick response, data transmission and management on demand based on HTTP, data block hash and store, uniform file view are implemented. Compared with commonly distributed file sys-tems EOS, GlusterFS and Lustre, availability in WAN, insensitivity to network delay and high-performance data access are performed.关键词
