2. ACTIVITY REPORT

2.1. Progress Summary

In the reported period NGI_DE keeps the Grid running smoothly in the region. 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. While keeping the Grid running, NGI_DE made efforts during the last three months in optimizing the use of computing resources and the quality of services. For example, KIT split a cluster into two clusters for efficiency and Uni-Dresden also split a cluster into two to run different OS versions for better services. A new site, FZJuelich, joined NGI-DE and is providing Grid services. The certification of the ZIB site is in progress.

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. New CREAM-CEs were installed. The following are concrete achievements of some sites:

• TUDresden-ZIH installed glite-Apel and a CREAM-CE.
• UNI-Wuppertal successfully performed the glite-Apel migration.
• In DESY-HH more storage was committed. As a result DESY-HH now provides 2PB disk storage in three SE's (atlas,cms and others) with better efficiency for the grid jobs and better distribution of the data on the storage (average efficiency of the jobs on grid-wn's is more than 80% in January). The CEs of DESY-HH are very well occupied with the jobs, for example, in 4 of the 7 days in the second January week, 100% of the job slots were occupied with the jobs. DESY-HH also updated one of the SEs (cms) to the 1.9.10 dcache version (outside of golden release).
• To enhance the efficiency, KIT split a cluster into two clusters and solved all related problems.
• Uni-Dresden split cluster in two OS versions (one half with SL and one cluster with slash).
• FZJ was certified as an EGI site. Now the service endpoints dcache.fz-juelich.de and site-bdii.fz-juelich.de are in production and a first UNICORE service endpoint was registered in GOCDB.
• UNI-Freiburg installed a CREAM-CE.
• LRZ upgraded the hardware on compute nodes and storage nodes and performed the migration from SLES10 to SLES11.
• SCAI migrated glite-MON to APEL, deployed glite-UI 3.2, replaced Nagios with Icinga, and performed decommission of LCG-CE.

2.3. Issues and mitigation

Issue Description	Mitigation Description
DESY-HH received increasing interest from the hosted VOs for the support of the glite on 32 bits platform.	This issue will be discussed in the NGI_DE and EGI User Forum in April.
FZJ reported a problem with integrating UNICORE resources.	It is needed that GOGDB supports adding new endpointURL fields for endpoint service types. A ticket was issued https://rt.egi.eu/rt/Ticket/Display.html?id=975, and it is still open. A solution is needed for properly adding UNICORE services to the EGI infrastructure.

2.4. Plans for the next period

• TUDresden-ZIH plans to increase the size of dCache installation (10 TB more disc).
• UNI-Wuppertal plans to install a CREAM CE.
• DESY-HH plans commissioning the large portion of the storage (~1PB) and a hardware evaluation for the WN's procurement.
• FZJ prepares "UNICORE Services for EGI - Tutorial for Resource Providers" for the EGI User Forum 2011.
• MPPMU plans to update Apel/monbox, and deploy new storage and worker nodes.
• SCAI plans a middleware migration to gLite 3.2 for SE, LFC & VOMS.
• KIT plans to organize an EGI-CSIRT face-to-face meeting in April in Karlsruhe,
