Description
We describe a relatively new effort within CMS to converge on a set of web based
tools, using state of the art industry techniques, to engage with the CMS offline
computing system. CMS collaborators require tools to monitor various components of
the computing system and interact with the system itself. The current state of the
various CMS web tools is described along side current planned developments.
The CMS collaboration comprises of nearly 3000 people from all over the world. As
well as its collaborators, its computing resources are spread all over globe and are
accessed via the LHC grid to run analysis, large scale production and data transfer
tasks. Due to the distributed nature of collaborators effective provision of
collaborative tools is essential to maximise physics exploitation of the CMS
experiment, especially when the size of the CMS data set is considered. CMS has
chosen to provide such tools over the world wide web as a top level service, enabling
all members of the collaboration to interact with the various offline computing
components. Traditionally web interfaces have been added in HEP experiments as an
afterthought. In the CMS offline we have decided to put web interfaces, and the
development of a common CMS web framework, on an equal footing with the rest of the
offline development.
Tools exist within CMS to transfer and catalogue data (PhEDEx and DBS/DLS), run Monte
Carlo production (ProdAgent) and submit analysis (CRAB). Effective human interfaces
to these systems are required for users with different agendas and practical
knowledge of the systems to effectively use the CMS computing system. The CMS web
tools project aims to provide a consistent interface to all these tools.
