2. ACTIVITY REPORT

2.1. Progress Summary

A great success in the reported period is that NGI_DE (mainly the KIT site) largely increased the tap capacity. In addition, all Grid services ran smoothly. The ROD team worked well. New hardware was installed and service software was upgraded. Stage rollout was performed.

2.2. Main Achievements

The following are concrete achievements of the NGI-DE sites:

  • FZJ contributed to UNICORE Integration Task Force; perpared the certification process for pure UNICORE sites; and participated ROD shifts for NGI-DE. This site is palnning to solve site certification and OLA issues in the next projrct quarter.
  • KIT updated gLexec on WNs and organized the Usage and future maintenance of deployed software Operations/Platform Deployment Survey
  • SCAI applied a gLite WMS from EMI to replace the old gLite 3.1 WMS instance and participated in the ROD shifts
  • DESY-HH made smooth running on EMI release (not wn's, cream). More space was added to dcache SE's, forming now 4.3PB in total, which is distributed over 3 production dcache instances. New pledges for the WLCG (from 01.04.2012) were fulfilled both in CPU and storage.
  • Wuppertal did migration to CREAM (in parallel, old CE still in use for a limited period of time) and migration from PBS to SGE; installed new hardware (ATLAS pledge fulfilled in time). This site is now included in the HEPPI/LHCone network.
  • MPPMU upgraded CREAM2 (glite-CREAM was moved from 3.2.13-1 to 3.2.14-1.sl5, glite-SGE_utils.x86_64 3.2.3-1.sl5) and performed security fix on Apel service.
  • LRZ participated the ROD shifts and the staged rollout.

2.3. Issues and mitigation

Issue Description Mitigation Description
TU-Dresden had problem with high load in file system vendor is trying to find a workaround
FZJ reported: Resource Centre Certification and Resource Centre Operational Level Agreement procedures and requirements as currently established do not match the reality of sites offering UNICORE services. Discussions in the UNICORE Integration Task Force are ongoing.
DESY-HH encountered slow response from emi on the problems raised (as example, to use UI) we need tarball distribution and ticket about this is more than 6 months old
Wuppertal reported problem with HEPPI/LHCone: still open questions about routing, it is unclear which sites are included and where this is decided. LBL was included after we complained, but still SARA/NIKHEF is not routed through that network. As your remaining DFN line is thin, this is causing trouble.
MPPMU encountered LFC failures due to "Bad magic number": hanging gpfs connections causing lfc timeouts. The work around was to change CREAM config to decrease gpfs load.
