Swiss National Supercomputing Centre is the national high-performance computing centre located in Manno, Ticino, established to provide supercomputing resources for Swiss research and industry. It operates large-scale computing systems to support computational science across physics, climate science, biology, and engineering, and coordinates national initiatives in digital research infrastructures. The centre contributes to European and global computational projects and hosts infrastructure for fast data storage and scientific visualization.

History

CSCS traces origins to the early 1990s when Swiss academics sought national computing capacity to support projects at ETH Zurich, Ecole Polytechnique Fédérale de Lausanne, and other institutions. Early milestones include procurement cycles influenced by developments at Los Alamos National Laboratory, CERN, and procurement patterns similar to National Center for Supercomputing Applications. The centre moved to a purpose-built facility in Manno following expansions driven by demand from groups such as Paul Scherrer Institute, Swiss Federal Institute of Technology in Zurich, and collaborations with IBM, Cray Research, and Intel. Leadership transitions involved figures with links to European Centre for Medium-Range Weather Forecasts, Max Planck Society, and Hermann von Helmholtz Association-affiliated researchers. CSCS’s history includes participation in projects aligned with Horizon 2020, contributions to EuroHPC Joint Undertaking, and hosting systems benchmarked against TOP500 lists alongside centres like Leibniz Supercomputing Centre and Barcelona Supercomputing Center.

Facilities and Infrastructure

The centre’s Manno campus contains data halls, energy-efficient cooling inspired by designs at Finnish Meteorological Institute sites, and redundant power systems comparable to installations at Swiss Federal Railways facilities. Infrastructure supports petascale workloads with fiber connectivity to European Grid Infrastructure nodes and links to national networks such as SWITCH. Storage arrays use architectures similar to those at National Energy Research Scientific Computing Center and Oak Ridge National Laboratory, while visualization suites echo designs from The Alan Turing Institute and National Supercomputing Centre (Singapore). The site complies with Swiss cantonal regulations and is located near infrastructure projects tied to Ticino development plans and transport links to Zurich and Lugano.

Supercomputing Systems

CSCS operates successive generations of supercomputers acquired from vendors including Cray Inc., Hewlett Packard Enterprise, NVIDIA, and Lenovo. Notable systems have been provisioned for simulations in climate change modeling groups affiliated with Intergovernmental Panel on Climate Change authors and for materials science teams working on projects related to European XFEL and Swiss Light Source. Hardware stacks combine many-core processors from AMD and Intel Corporation, accelerators from NVIDIA Corporation, and interconnects resembling designs from InfiniBand vendors used at Argonne National Laboratory. System benchmarks and architecture studies have been published in venues such as ACM and IEEE conferences, and CSCS systems have appeared on the TOP500 list.

Services and Research Support

CSCS provides users with batch and interactive access, workflow management similar to services at PRACE, and support for code optimization practiced at Lawrence Berkeley National Laboratory. It offers training programs modeled on curricula from European Grid Infrastructure partners and runs user support analogous to services at National Computational Infrastructure (Australia). Research support includes assistance for high-performance I/O, visualization compatible with ParaView workflows, and containerization strategies influenced by Docker and Singularity adoption at Swiss Institute of Bioinformatics projects. CSCS staff collaborate with principal investigators from University of Zurich, University of Geneva, EPFL, and industrial partners such as Roche and ABB.

Governance and Funding

Governance structures link CSCS to ETH Board and oversight practices comparable to other Swiss research infrastructures, with strategic interactions involving State Secretariat for Education, Research and Innovation stakeholders. Funding sources include competitive grants from Swiss National Science Foundation, allocations from Swiss Federal Office for Science, Education and Innovation, and co-funding through European mechanisms including Horizon Europe and European Regional Development Fund. Procurement and review cycles follow standards adopted by Swiss Federal Audit Office-related guidance, and strategic planning aligns with roadmaps similar to those published by EuroHPC.

Collaborations and Partnerships

CSCS partners with national laboratories such as Paul Scherrer Institute and universities including University of Basel, University of Bern, and University of Lausanne, and maintains joint projects with European centers like PRACE and Leibniz Supercomputing Centre. Industrial collaborations involve companies such as Novartis, ABB, and Google research collaborations, while technology partnerships include vendors like NVIDIA and HPE. International cooperation extends to collaborations with CERN for data-intensive workflows, with climate consortia connected to ECMWF and with materials science networks associated with European Synchrotron Radiation Facility.
