Mastering challenges of High-Luminosity LHC data with innovative computing solutions — •Michael Boehler — Albert-Ludwigs-Universität, Freiburg, Germany

The Worldwide LHC Computing Grid was founded in 2004 to store, distribute, and analyse the huge amounts of data of the LHC experiments. It combines the computing and storage resources of over 170 compute centres in more than 40 countries. Around 10 of these centres are located in Germany. The current data volume of 200 petabytes per year will increase to exabytes per year with the launch of the High-Luminosity LHC in 2029. The demand for computing resources will also increase dramatically unless drastic savings are achieved through aggressive research and development in the area of data processing. In addition, the sharp increase in energy prices in the last year and the general consensus on energy conservation require sustainable computing solutions.

A selection of tools, further developments, and innovative ideas will be presented that are essential for overcoming these challenges. Important building blocks for this task are applications that make it possible to integrate heterogeneous resources transparently and dynamically into existing high-energy physics workflows. The accounting ecosystem AUDITOR and the meta-scheduler CobalD/TARDIS, which were developed in Germany in the FIDIUM project, make it possible to break new ground.
