Description
CRAB (Cms Remote Analysis Builder) is a tool, developed by INFN within the CMS
collaboration, which provides to physicists the possibility to analyze large amount
of data exploiting the huge computing power of grid distributed systems. It's
currently used to analyze simulated data needed to prepare the Physics Technical
Design Report. Data produced by CMS are distributed among several Computing Centers,
and CRAB allows a generic users, without specific knowledge of grid infrastracture,
to access and analyze those remote data, hiding the complexity of distributed
computational services and making job submission and management as simple as in a
local environment. The experience gained during the current CMS distributed data
analysis effort is reported, along with CRAB ongoing developments. The interaction of
CRAB with the actual and future CMS Data Management services is described, as well as
the usage of WLCG/gLite/OSG middleware to provide access to different grid
environments. Finally, the use within CRAB of BOSS for logging, bookkeeping and
monitoring is presented.
