2. ACTIVITY REPORT

2.1. Progress Summary

CSCS

• Miguel Gila started on the 1st of April and replaces Peter Oettl who leaves on April 30th

PSI

• New system engineer joined our team in February
• Started to offer an additional number of UI machines for more interactive work

UZH

• Sergio Maffioletti has been formally assigned as ARC Staged Rollout manager together with Christian Ulrik Soettrup (NBI - DK)

• Preparation for the ARC Early Adopters activities (included infrastructure setup)

• Established contact with the Computational Chemistry Competence Center (C4) at ETH Zurich. A series of usecases has been identified. The porting to the national infrastructure will be implemented by the GC3 group.

• Followup with the CompChem VO for implementing a series of usecases from user group from University of Perugia (UniPE) using the tools developed by the GC3 group. In the next quarter, a researcher from UniPE will be visiting UZH.

• Contacted Earth VO group (Horst Schwichtenberg) for exploring possible followups in some solutions adopted within 'earth' VO in SMSCG

2.2. Main Achievements

CSCS

• Upgraded cluster by adding 10 Worker Nodes with 240 total cores. Increased storage capacity by 232 TB.
• GPFS introduced to replace Lustre as scratch in the future.
• Participated in staged rollout of gLite CREAM, gLite WN, gLite Torque utils and gLite Torque client for gLite 3.2
• LCG-CEs decommissioned.
• Created a new queue for high-memory ATLAS jobs.
• Migration of SUN Thumpers from Solaris to Linux.

PSI

• improved resilience of the system by a new Nagios service, better low level HW monitoring, centralized backups

SWITCH

• Prepared Monitoring Host forseti.switch.ch to run with gLite and ARC tests. Need to decide on putting into operation.

2.3. Issues and mitigation

Issue Description	Mitigation Description
CSCS encountered excessive usage of find, du and ls commands that slowed down the parallel filesystem.	Reported to VOs trying to minimize usage of those commands.
Oracle takeover of SUN affects PSI: It has been confirmed that we cannot get any more Solaris10 updates for our systems without buying maintenance contracts.	PSI will continue to run the latest free version of Solaris10.
At the moment the international CompChem community seems to be rather disjointed.	---
