Supercomputer - Alps/Eiger

The Alps/Eiger supercomputer is a highly specialized HPC system for massively parallel applications or for applications with distributed memory needs (see detailled specifications).

  • Supercomputer service for research
  • Targeted to address the largest-scale computational research
  • Provides access to CPUs on an HPE Cray EX multiprocessor system
  • System operated by the Swiss National Computing Centre (ETHZ/CSCS)
  • Selection of pre-installed applications available

With Eiger you can run massively parallel workflows, profiting from the high-speed interconnect among the nodes.

Additional information:


The Supercomputer service is accompanied by support from Science IT experts, removing not only the overhead of setting up your local hardware systems and servers, but also providing you access to new skills and expertise.
