HEP Applications Experience with the European DataGrid Middleware and Testbed
Content:
The European DataGrid (EDG) project ran from 2001 to 2004, with the aim of
producing
middleware which could form the basis of a production Grid, and of running a
testbed
to demonstrate the middleware. HEP experiments (initially the four LHC
experiments
and subsequently BaBar and D0) were involved from the start in specifying
requirements, and subsequently in evaluating the performance of the
middleware, both
with generic tests and through increasingly complex data challenges. A lot
of
experience has therefore been gained which may be valuable to future Grid
projects,
in particular LCG and EGEE which are using a substantial amount of the
middleware
developed in EDG. We report our experiences with job submission, data
management and
mass storage, information and monitoring systems, Virtual Organisation
management
and Grid operations, and compare them with some typical Use Cases defined in
the
context of LCG. We also describe some of the main lessons learnt from the
project,
in particular in relation to configuration, fault-tolerance,
interoperability and
scalability, as well as the software development process itself, and point
out some
areas where further work is needed. We also make some comments on how these
issues
are being addressed in LCG and EGEE.
