Development was carried out using the 1800 CPU Tier2 centre at Manchester and the local user community. The worker nodes run an afs client system, and the gssklog program is used to connect running jobs to the local afs server.
Several user projects have been and are being successfully undertaken using this, in the areas of accelerator simulation, reactor studies, and particle physics data analysis. We describe these cases and the lessons learned from them.
Using this system users can run jobs on the Tier 2 centre in exactly the same environment as when running test jobs on the local cluster. This makes the path the online test and debugging environment to the offline production environment extremely smooth.
This system provides a way of opening up the facilities of a large Grid centre to a user with minimal adaptation on
their part, and has encouraged our transition to grid computing. Other centres and other users will be interested in adopting this system.
Conclusions and Future Work
This is a successful lightweight system which makes access by users considerably easier and encourages
use of the centre, and speeds up their computing tasks
