Description
INFN-CNAF, the Italian WLCG Tier1, runs a large HTCondor cluster, providing computing resources to many scientific collaborations in the fields of High-Energy Physics, Astroparticle Physics, Gravitational Waves, Nuclear Physics and many others.
For both the Tier1 and the collaborations, it’s crucial to have a grasp on the overall usage of computing resources. In the last few years at CNAF the accounting of CPU resources relied on a custom infrastructure that has proved to be not reliable and difficult to maintain.
A promising alternative is AUDITOR (AccoUnting DatahandlIng Toolbox for Opportunistic Resources), a flexible and extensible accounting ecosystem that can cover a wide range of use cases and infrastructures. It is based on data-gathering software programs called collectors that store information in a database. Additional pieces of software, called plugins, can access the data to provide accounting information. We recently setup a testbed in order to validate AUDITOR as a possible alternative to the current system in production.
This contribution will cover the current state of the accounting infrastructure at INFN-T1, the experience on setting up AUDITOR based accounting and future developments.
