Caching in Distributed Computing Infrastructures — •Robin Hofsaess, Maximilian Horzela, Manuel Giffels, Artur Gottman, and Matthias Schnepf — Karlsruher Institut für Technologie

With the steadily growing amount of data collected in several high energy physics experiments, new challenges occur when it comes to an efficient processing of the data. Besides storage, data transfers are becoming more and more limiting for the increasingly distributed computing infrastructure used by the HEP community. An efficient usage of the resources therefore make higher bandwidths necessary. However, it is often not possible to simply improve the connectivity of a resource provider leading to the necessity of other approaches. A first step here could be to reduce unnecessary data transfers by (local) caching. The talk will address the general ideas on coordinated caching within a distributed computing infrastructure - as given at KIT/GridKa - and briefly discuss its challenges. Furthermore, our future plans at KIT will be presented.
