Description

The 14th Thematic CERN School of Computing (tCSC 2024) will take place on June 9-15, 2024. The theme of the school is "Scientific Software for Heterogeneous Architectures" - see the academic programme for more details.

This school is organized by CERN in collaboration with the Information Technology School (ITS), situated at the Comtrade Campus in Belgrade, Serbia. CSC students will have access to modern lecture rooms, labs and a sports hall as well as restaurants and cafeterias. The campus is situated in the new Belgrade area by the Danube river, only a short busride from the old city center of Belgrade

The School is aimed at postgraduate (i.e. minimum of Bachelor degree or equivalent) students, engineers and scientists with a few years' experience in particle physics, in computing, or in related fields. We welcome applications from all countries and nationalities.

Important Dates

  • Wednesday March 27 - applications deadline
  • Wednesday April 10 - invitations sent to the selected participants
  • Wednesday May 8  - registration fee payment deadline
  • Sunday June 9 - Saturday June 15- the school

      Preparing for the HL-LHC computational challenge ITS - IT Club

      ITS - IT Club

      In this talk we will introduce some basic concepts related to HEP data processing and analysis workflows, seeing them in action in the context of LHC experiments. We’ll also talk about the evolution of the LHC accelerator and experiments. We’ll characterise at a high level what are the consequences of those upgrades for the HEP data processing software, in particular in the context of an evolving hardware and computing infrastructure.
