2. ACTIVITY REPORT
2.1. Progress Summary
In the reported period NGI_DE keeps the Grid running smoothly in the region. Availability and Reliability was kept high (96% in average). Operation problems are discussed in the regular coordination meeting. The ROD team works well. Grid services are maintained up-to-date. Security update was done by all sites. The sites regularly participated in Grid operations meetings as well as GOCDB regionalization and UNICORE integration task force meetings.
Two VO subgroups, /dteam/NGI_DE and /dteam/NGI_CH, were created. Most of the sites already support theses VOs and passed the test. New support unit for NGI_DE monitoring was integrated in helpdesk to cover the case of problems with the common monitoring tools like nagios, dashboard, myegi etc. The regional nagios monitoring instance is now using the VO subgroup "/ops/NGI/Germany". All the NGI-DE and NGI-CH sites enabled the support for this subgroup.
2.2. Main Achievements
The main achievements of NGI_DE in the report period are the successful operation of the Grid infrastructure in the entire region. Some sites participated in Staged Rollout. All sites have patched the security vulnerabilities in time. Regional Nagios instance was updated to the latest version SAM09. New CREAM-CEs were installed. The following are concrete achievements of some sites:
- MPPMU replaced the monbox, migrated the CREAM CE and sBDII to new HW, added some WNs and storage systems, and installed 240TB disk space. Currently, this site is moving forward towards the glite 3.2 on SL(C)5 infrastructure (until now SLES are used on the CEs). The migration/upgrade is planned to be finished in May.
- DESY-HH increased storage capacity.
- In TUDresden-ZIH, the production infrastructure works quite stable; some minor problems with dCache were fixed. This site also migrated monbox to glite-APEL and started to support VO BIOmed in the reported period.
- Uni-Freibiurg installed a set of new worker nodes and a second CREAM CE. It also installed 400TB new storage.
- KIT adopted new CREAM CEs and WMS in production. It also updated successfully the top level BDII and migrated monbox to glite-APEL. This site prepared the annual NGI_DE conference in May.
- WUPPERTAL successfully performed upgrade to the new dCache release 1.9.12-1 (the new "golden release") and upgrade the Cluster file system Lustre to Lustre 1.8.4 (SFS 3.2-3).
- FZJ contributed to the UNICORE Integration Task Force and organized the UNICORE Tutorial for resource providers at EGI User Forum. An early adoption of EMI 1.0 UNICORE services is planned for the next quarter.
- ITWM upgraded their CEs as well as SEs and performed BDII staged rollout.
- BMRZ-Frankfurt updated CEs, WNs, sBDII etc.
- SCAI performed BDII site migration to gLite 3.2, decommission of glite-wms2, and the preparation of VOMS, SE and LFC migration. Torque/Maui was also upgraded to 2.5.x.
- In LRZ-LMU, Dell storage server was brought into production in an inhomogeneous environment (SLES10 / SLES11); dCache was maintained up to date in the current stable release branch (1.9.5). LRZ-LMU also deployed dCache on the new pools and migrated the whole dCache cluster to use BDB based file meta-data. A dCache migration to the next golden release and using new high performance (1Tb RAM) service node for dCache were planned for the near future.
