In order to improve its batch service for local and Grid users, development is ongoing at CERN to design a batch monitoring system and set up a test instance. The goal is to enhance the batch service by investigating new scheduler features, fine-tuning the already used ones and decreasing the time spent in problem identification and fault resolution.

Reliable benchmarking of file systems is a complex and time consuming task when one has to test against a production environment to achieve relevant results. In case of the HEP community, this eventually leads to setting up a particular experiments' software environment, which could be a rather complicated task for a system administrator. To simplify this task, we developed an application for ... More
