Abstract

Supporting three of the four main user communities of the Large Hadron Collider (LHC) at CERN, RO-07-NIPNE is the most complex grid site of the Romanian Tier-2 Federation (RO-LCG, http://lcg.nipne.ro). Here we present an overview of the recent hardware, software and network implementations at the grid site, in view of the computational support for the second run of the LHC. Special emphasis is placed on the site upgrade through the adoption of new technological solutions for job and data management, such as the installation of the Advanced Resource Connector (ARC) Compute Element for the parallel processing of ATLAS jobs and the implementation of the SLURM resource manager. A review on the upgrade of the hardware infrastructure is presented, including the commissioning of a new SAN system that completed the Tier-2 with Data storage capacity dedicated to the LHCb collaboration. Also, the improvements of the network connectivity, for the enhancement of the availability of the IFIN-HH's grid sites, and the re-inclusion of RO-07-NIPNE in the LHCONE virtual private network are shortly discussed.

在IFIN-HH的WLCG站点的新发展

RO-07-NIPNE支持CERN大型强子对撞机(LHC)的四个主要用户社区中的三个，是罗马尼亚二级联盟(RO-LCG, http://lcg.nipne.ro)中最复杂的网格站点。鉴于LHC第二次运行的计算支持，我们在这里概述了网格站点最近的硬件、软件和网络实现。特别强调的是通过采用作业和数据管理的新技术解决方案来进行站点升级，例如安装用于并行处理ATLAS作业的高级资源连接器(ARC)计算元素和实施SLURM资源管理器。对硬件基础设施的升级进行了回顾，包括新SAN系统的调试，该系统完成了用于LHCb协作的具有专用数据存储容量的第2层。此外，本文还简要讨论了网络连接性的改进，以增强IFIN-HH网格站点的可用性，以及将RO-07-NIPNE重新纳入LHCONE虚拟专用网络。
