Description
The computing infrastructures serving the LHC experiments have been
designed to cope at most with the average amount of data recorded. The
usage peaks, as already observed in Run-I, may however originate large
backlogs, thus delaying the completion of the data reconstruction and
ultimately the data availability for physics analysis. In order to
cope with the production peaks, the LHC experiments are exploring the
opportunity to access Cloud resources provided by external partners
or commercial providers.
In this work we present the proof of concept of the elastic extension
of a local analysis facility, specifically the Bologna Tier-3 Grid
site, fot the LHC experiments hosted at the site,
on an external OpenStack infrastructure. We focus on the “Cloud
Bursting" of the Grid site using DynFarm, a newly designed tool
that allows the dynamic registration of new worker nodes
to LSF. In this approach, the dynamically added worker nodes
instantiated on the OpenStack infrastructure are transparently
accessed by the LHC Grid tools and at the same time they serve as an
extension of the farm for the local usage.
