Scheduling heterogeneous resources for federated usage — René Caspart, •R. Florian von Cube, Tabea Feßenbecker, Max Fischer, Manuel Giffels, Christoph Heidecker, Maximilian Horzela, Eileen Kühn, Günter Quast, and Matthias Schnepf — Karlsruhe Institute of Technology

To overcome shortcomings in computing resources, the opportunistic usage of additional resources, not specifically dedicated to HEP, can help. Such resources might be HPC centers, or commercial and institutional cloud providers. An overlay batch system is used to provide a single point of entry to this plethora of resources and enables transparent usage for the user.

A novel on-demand resource management system COBalD/TARDIS has been developed and extensively tested at KIT to allocate and integrate such resources. Small computing centers are enabled to contribute computing resources to the grid in a very light-weight manner using those services. Such resources can be connected, allowing for jobs to move freely between different batch system instances.

In this contribution we present the latest software developments and the progress made in applications in terms of federating resource pools.
