Due to COVID-19, the Thematic CERN School of Computing 2020 is cancelled. Thank you for your interest in the school, and we hope to welcome you at the tCSC 2021. 

---

The 8th Thematic CERN School of Computing (tCSC 2020) will take place on June 7-13, 2020 in the city of Split, Croatia.

The theme of the School is "Efficient Scientific Software for Heterogeneous Architectures" - see the academic programme for more details.

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.

Applications are now closed.

tCSC 2020 is organized by CERN in collaboration with the University of Split (FESB) and is hosted at the Mediterranean Institute For Life Sciences (MEDILS) Conference Centre. The Centre is a historical renovated building situated in a wooded and landscaped park located on the Adriatic Sea coast, a few kilometres from the centre of Split.
