摘要：

为了对大型实验进行数据分析，如LHC Atlas和其他日本高能和核物理项目，我们在ICEPP和KEK建造了一个网格测试台。这些研究所连接到国家科学千兆网络骨干称为SuperSINET。在我们的测试平台中，我们安装了基于Globus的NorduGrid中间件，并连接了KEK的120TB HPSS作为大规模数据存储。利用SuperSINET传输和访问了ICEPP的Atlas模拟数据。我们已经通过这个高速广域网测试了HPSS的各种性能和特性。测量包括计算和存储资源与低延迟LAN和长距离WAN紧密耦合之间的比较。

英文摘要：

For data analysis of large-scale experiments such as LHC Atlas and other Japanese high energy and nuclear physics projects, we have constructed a Grid test bed at ICEPP and KEK. These institutes are connected to national scientific gigabit network backbone called SuperSINET. In our test bed, we have installed NorduGrid middleware based on Globus, and connected 120TB HPSS at KEK as a large scale data store. Atlas simulation data at ICEPP has been transferred and accessed using SuperSINET. We have tested various performances and characteristics of HPSS through this high speed WAN. The measurement includes comparison between computing and storage resources are tightly coupled with low latency LAN and long distant WAN.
