Dynamic and transparent provisioning of opportunistic compute resources for HEP — •Ralf Florian von Cube, René Caspart, Max Fischer, Manuel Giffels, Eileen Kühn, Günter Quast, and Matthias Schnepf — Karlsruhe Institute of Technology

The utilization of only temporarily available compute resources (opportunistic resources) not dedicated to HEP becomes more and more important for future HEP experiments. On the one hand, due to the unprecedented need and resulting scarcity of HEP compute resources. On the other hand, due to the desired integration of HPC, Cloud and locally available resources.

To meet the challenges posed by the resulting heterogeneous compute environment, the Karlsruhe Institute of Technology (KIT) developed the COBalD/TARDIS resource manager and an entire ecosystem around an HTCondor overlay batch system to allow for a dynamic, transparent and hassle-free integration of those resources into the World-wide LHC Computing Grid (WLCG) via a single point of entry.

In this contribution we will present the current status of COBalD/TARDIS developments as well as our experience with the integration of various opportunistic resources into the WLCG.
