Report on the experience (or the proposed activity). It would be very important to mention key services which are essential for the success of your activity on the EGEE infrastructure.
GridPP was setup primarily to provide, and help enable High Energy Physics
applications to make use of, Grid resources. In practice the deployment and
operations team of GridPP (which also form a large part of the EGEE UK&I ROC) spend
time ensuring that a much broader community can use the Grid. Thus we can relay
experience working with HEP groups outside of the LHC world, non-HEP groups such as
the biomedical community and business applications (such as Cambridge Ontology and
TOTAL E&P).
With a forward look to future evolution, discuss the issues you have encountered (or that you expect) in using the EGEE infrastructure. Wherever possible, point out the experience limitations (both in terms of existing services or missing functionality)
- Requirements of large vs small VOs and how they interact with the grid resource
providers - Common problems in specifying job parameters
- VO local disk requirements
- Centralised monitoring of jobs
- Feedback on job failure reasons
- Keeping the grid secure
- Testing sites vs VO environment needs
- Working with users to resolve problems (via GGUS)
- VOMS groups and roles
Describe the added value of the Grid for the scientific/technical activity you (plan to) do on the Grid. This should include the scale of the activity and of the potential user community and the relevance for other scientific or business applications
The Grid is what the authors of this abstract are providing so this question is not
possible to answer directly. Our project existence is based on the defined need for
distributed computing that can cope with the data output and processing associated
with experiments that will come on line with the Large Hadron Collider at CERN later
this year. There are thousands of scientists associated with this project, hundreds
of whom are in the UK. In addition we work with scientists from other areas of High
Energy Physics and Science to explore the potential value of Grid computing.
Describe the scientific/technical community and the scientific/technical activity using (planning to use) the EGEE infrastructure. A high-level description is needed (neither a detailed specialist report nor a list of references).
GridPP is the major provider of EGEE resources in the UK and Ireland region. The
community represented spans individual site administrators to regional coordination
bodies.
