Edinburgh Activity

The Edinburgh group's work on Atlas Distributed Computing has so far focused in three areas:

1. Supporting sites involved in DDM with a focus on UK and /or DPM centres.

We have built expertise in the widely used storage resource (SRM) solution DPM and used this to support sites in the UK through UK (GridPP) wiki pages and discussion forums. In addition we are developing and maintaining dpm tools to assist sites in supporting ATLAS specific requirements, such as a recent tool to replicate files within the new ATLASHOTDISK spacetoken, and ongoing work to determine missing or corrupted files within ATLAS spacetokens at DPM sites. We are also building capacity within the UK to support the alternative SRM StoRM. Other work in this area included supporting the development of tools to check file integrity - including the checksums of ATLAS data at UK Tier 2 sites.

2. Developing monitoring tools for DDM monitoring

Edinburgh have begun working within the DDM dashboard "sandbox" to develop new plots to aid DDM operations. It is expected that these will be integrated into existing plans for DDM monitoring development.

3. Supporting general ADC operations through shifts and other distributed production support.

Members of the group are undertaking ADCoS shifts - now as "senior" shifters. We expect, through experience gained, that we will play a significant role in supporting ADC operations in the future either as ADCoS "experts" or through direct support to sites in, for example, optimising their storage systems for ATLAS analysis.
