Performance gain in HEP workflows via coordinated caches in heterogenous distributed systems — Rene Caspart, Tabea Feßenbecker, Max Fischer, Manuel Giffels, Christoph Heidecker, •Maximilian Horzela, Eileen Kühn, Günter Quast, and Paul Skopnik — Karlsruhe Institute of Technology

The steadily increasing demand on compute resources due to an explosively growing amount of data and demand for simulations for analysis purposes particularly in the context of the High Luminosity LHC can only be covered by harnessing novel computing concepts.

Besides the integration of additional resources, a promising approach to meet the need for resources is to improve the efficiencies of the workflows. In the HEP community these are often limited by the I/O bandwidth. Nevertheless, to utilize the full available computational capacities of distributed computational systems, aiming for optimal efficiency, coordinated caching solutions in combination with data-locality aware batch systems can provide a significant contribution.

This talk outlines basic concepts and visions for coordinated caching solutions in heterogeneous distributed batch systems.
