摘要

巴基斯坦的国家物理中心(NCP)为科学界维护着一个计算基础设施。通过WLCG基础设施为CMS实验预留了大部分计算和存储资源,为其他非实验高能物理(EHEP)科学实验预留了一小部分计算资源。为了有效地利用资源,许多科学组织已经将其资源迁移到基础设施即服务(IaaS)设施中。NCP去年也采取了这样的举措,并将其大部分资源迁移到IaaS设施中。一个基于HT-condor的批处理系统已经为当地的高能物理实验社区部署,使他们能够执行他们的分析任务。最近,我们部署了一个HT-Condor计算元素(CE)作为CMS作业的网关。在网络方面,我们的Tier-2站点完全可以在IPv6上访问和运行。此外,我们最近部署了一个Perfsonar节点来主动监控NCP和其他WLCG站点之间的吞吐量和延迟问题。本文讨论了NCP二级站点的现状、面临的挑战和未来的发展方向。

WLCG Tier-2 site at NCP, Status Update and Future Direction
The National Centre for Physics (NCP) in Pakistan maintains a computing infrastructure for the scientific community. A major portion of the computing and storage resources are reserved for the CMS experiment through the WLCG infrastructure, and a small portion of the computing resources are reserved for other non experimental high-energy physics (EHEP) scientific experiments. For efficient utilization of resources, many scientific organizations have migrated their resources into infrastructure-as-a-service (IaaS) facilities. The NCP has also taken such an initiative last year, and has migrated most of their resources into an IaaS facility. An HT-condor based batch system has been deployed for the local experimental high energy physics community to allow them to perform their analysis task. Recently we deployed an HT-Condor compute element (CE) as a gateway for the CMS jobs. On the network side, our Tier-2 site is completely accessible and operational on IPv6. Moreover, we recently deployed a Perfsonar node to actively monitor the throughput and latency issues between NCP and other WLCG sites. This paper discusses the status of NCP Tier-2 site, its current challenges and future directions.
