The Swiss National Supercomputing Centre (Italian: Centro Svizzero di Calcolo Scientifico; CSCS) is the national high-performance computing centre of Switzerland. It was founded in Manno, canton Ticino, in 1991.In March 2012, the CSCS moved to its new location in Lugano-Cornaredo. The main function of the Swiss National Supercomputing Centre is a so-called National User Lab. It is open to all Swiss researchers and their assistants, who can get free access to CSCS supercomputers in a competitive scientific evaluation process. In addition, the centre operates dedicated computing facilities for specific research projects and national mandates, e.g. weather forecasting. It is the national competence centre for high-performance computing and serves as a technology platform for Swiss research in computational science. CSCS is an autonomous unit of the Swiss Federal Institute of Technology in Zurich (ETH Zurich) and closely collaborates with the local University of Lugano (USI).
