2. ACTIVITY REPORT

2.1. Progress Summary

PSI has been able to hire an additional system administrator with main responsibility for the PSI T3. Start of work: Feb 1st 2011

UZH established several contacts within comp.chem VO and within former chemomentum project. Established also contact with relevant comp.chem potential partners in Switzerland

2.2. Main Achievements

CSCS

  • Participated in staged rollout of gLite CREAM 3.2
  • Reformatted Lustre with ext4 which increased performance of the fs and decreased the load on the servers

UZH advocated their tools (GC3pie also part of the EGI application DB) as a tool to facilitate the migration of existing comp.chem usecases towards the NGI-CH national infrastructure and towards EGI

2.3. Issues and mitigation

Issue Description Mitigation Description
PSI: Some insecurity due to takeover of SUN by Oracle. Our Storage is based on Sun X4500/X4540 and Solaris as dcache pool servers. The newest machines we bought in December, they now have been taken already out of the program by Oracle. Solaris updates seemingly can now only be gotten via a support contract. All of this forces us to reconsider the architecture this year. As queuing system we use SGE where the future with Oracle also is unclear.

Following up development of forked product for SGE. Investigating new storage infrastructure for expansion. Maybe freezing Solaris OS on present architecture and run it as long as we use these machines. Also need to study support costs.

UZH: It is interesting to note that most of the comp.chem group contacted were initially very reluctant on the idea of migrating some of their usecases on grid (being it national infrastructure or EGI)

There is the clear need to assist those groups and collaborate actively with them in order to facilitate the enabling/migration process. These groups seems to be interesting in such infrastructures only for supporting very large throughput; for this, standard available tool are not sufficient.

They need an easy way to control the throughput; for this tools like GANGA, or our G3pie seems to fill this gap. But lot of work has to be done together with these groups in order to migrate their usecases
