Abstract

This paper reports the design and implementation of a secure, wide area network, distributed filesystem by the ExTENCI project (Extending Science Through Enhanced National Cyber Infrastructure) based on lustre. The filesystem is used for remote access to analysis data from the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC), and from the Lattice Quantum ChromoDynamics (LQCD) project. Security is provided for by kerberos and reinforced with additional finegrained control using lustre ACLs and quotas. We show the impact of using kerberized lustre on the IO rates of CMS and LQCD applications on client nodes, both real and virtual. Pre-configured images of lustre virtual clients containing the complete software stack ease the difficulty of managing these systems.

在广域网上使用kerberos光泽处理高能物理数据

本文报告了基于lustre的ExTENCI项目(通过增强国家网络基础设施扩展科学)的安全、广域网、分布式文件系统的设计和实现。该文件系统用于远程访问大型强子对撞机(LHC)的紧凑型μ子螺线管(CMS)实验和晶格量子色动力学(LQCD)项目的分析数据。安全性由kerberos提供，并通过使用lustre acl和配额进行额外的细粒度控制来增强。我们展示了使用kerberos lustre对客户机节点(包括真实节点和虚拟节点)上CMS和LQCD应用程序的IO速率的影响。包含完整软件堆栈的lustre虚拟客户机的预配置映像减轻了管理这些系统的困难。
