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)
We had to establish our own rules for file naming schemes and registration to be able to
manage data on various SEs. Generic rules imposed by middleware and tools for data
consistency checks are needed.
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.
We developed a framework for submission of many simulation jobs with varying input
parameters. We will report on our activity of porting offline data processing to the
Grid. Experience from a data management in the VO auger will be given.
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).
The Pierre Auger Cosmic Ray Observatory is studying the universe's highest energy
particles, which shower down on Earth in the form of cosmic rays. Data recorded by
the experiment are analysed and compared with results from simulations. The Pierre
Auger Collaboration includes more than 250 scientists from 17 countries. All members
of the collaboration should have easy access to data.
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
There are two main features of the Grid important for the Auger collaboration. As a
global
collaboration, it benefits from a uniform access to data stored on Storage Elements and
registered in a catalogue. CPU requirements on simulations of the ultra high energy
cosmic rays are huge, possibility to use many CPUs connected via Grid enables to simulate
events with higher precision. We expect tens of active grid users accessing data and/or
running simulation jobs.
