The High Performance Computing and Emerging Technologies (HPCE) group provides a range of HPC services for PSI scientists and external collaborators, and also engages with PSI groups in research activities on technologies used on these systems.
HPC infrastructure managed by HPCE
PSI public systems
- Merlin: the 7th generation of the local PSI HPC systems was made available in 2025. It offers resources for PSI's mid-range HPC requirements and also contains a range of GPU nodes. The 6th generation cluster has been partially decommissioned, with access only available to a few PSI local groups.
- PSI share of the CSCS Daint on Alps supercomputer: PSI users have access to a share of Daint. Use of the PSI share is subject to a PSI internal proposal and evaluation by the PSI research commission (FOKO).
Dedicated special purpose systems
- LHC CMS/Tier-3: A cluster integrated into the LHC Grid focusing on end-user analysis of LHC data. It is operated and financed as a collaboration of the CMS groups of PSI, ETHZ, and UniZ. Operated for the High Energy Physics group.
- MEG data analysis cluster: A cluster tightly coupled to Merlin5 and dedicated to the analysis of data from the MEG experiment. Operated for the Muon Physics group.
