Sumario: | CMS has a distributed computing model, based on a hierarchy of tiered regional
computing centres. However, the end physicist is not interested in the details of the computing
model nor the complexity of the underlying infrastructure, but only to access and use efficiently
and easily the remote services. The CMS Remote Analysis Builder (CRAB) is the official CMS
tool that allows the access to the distributed data in a transparent way. We present the current
development direction, which is focused on improving the interface presented to the user and
adding intelligence to CRAB such that it can be used to automate more and more the work
done on behalf of user. We also present the status of deployment of the CRAB system and the
lessons learnt in deploying this tool to the CMS collaboration. |
