Description
DIRAC, the LHCb community Grid solution, was considerably
reengineered in order to meet all the requirements for processing the data
coming from the LHCb experiment. It is covering all the tasks starting
with raw data transportation from the experiment area to the grid storage,
data processing up to the final user analysis. The reengineered DIRAC3
version of the system includes a fully grid security compliant framework
for building service oriented distributed systems; complete Pilot Job
framework for creating efficient workload management systems; several
subsystems to manage high level operations like data production and
distribution management. The user interfaces of the DIRAC3 system
providing rich command line and scripting tools are complemented by a
full-featured Web portal providing users with a secure access to all the
details of the system status and ongoing activities.
We will present an overview of the DIRAC3 architecture, new innovative
features and the achieved performance. Extending DIRAC3 to manage computing
resources beyond the WLCG grid will be discussed. Experience with using
DIRAC3 by other user communities than LHCb and in other application domains
than High Energy Physics will be shown to demonstrate the general-purpose
nature of the system.
