New developments of the WLCG site at IFIN-HH

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.
