Description
The main goal of the Experiment Integration and Support (EIS) team in WLCG is to help
the LHC experiments with using proficiently the gLite middleware as part of their
computing framework. This contribution gives an overview of the activities of the EIS
team, and focuses on a few of them particularly important for the experiments. One
activity is the evaluation of the gLite workload management system (WMS) to assess
its adequacy for the needs of the LHC computing in terms of functionality,
reliability and scalability. We describe in detail how the experiment requirements
can be mapped to validation criteria, and the WMS performances are accurately
measured under realistic load conditions over prolonged periods of time. Another
activity is the integration of the Service Availability Monitoring system (SAM) with
the experiment monitoring framework. The SAM system is widely used in the EGEE
operations to identify malfunctions in Grid services, but it can be adapted to
perform the same function on experiment-specific services. We describe how this has
been done for some LHC experiments, which are now using SAM as part of their operations.
