Description
The LHCb experiment has chosen to use the SAM framework (Service Availability
Monitoring Environment) provided by the WLCG developers to make extensive tests of
the LHCb environment at all the accessible grid resources. The availability and the
proper definition of the local Computing and Storage Elements, user interfaces as
well as the WLCG software environment are checked.
The same framework is also used to pre-install the LHCb applications in the shared
software area provided by each site. The deployment of the LHCb applications is based
on a python tool developed inside the experiment. It is used for software management
including incremental installation of interdependent packages and clean package
removal. The software installation is followed by a full application run tests.
According to the results of the experiment specific SAM tests, the sites are allowed
to be used in the LHCb production system called DIRAC. The possibility of automated
dynamic site certification using the SAM test suite is explored.
This paper will describe the various ways of the LHCb use of the SAM framework.
Practical experience in the recent production runs, current limitations and future
developments will be presented.
