High performance computing

C2SM aims to prepare climate codes for the next generation of high-performance computers to exploit the emerging computing capabilities and thereby continue to contribute at the highest level to climate system science.

C2SM is involved in the Swiss external page Platform for Advanced Scientific Computing (PASC), which goal is to promote collaborations between domain scientists, computational scientists and software and hardware vendors and providers. C2SM's involvement in PASC strongly relies on the active collaboration between ETH and MeteoSwiss together with the external page Swiss National Supercomputing Center (CSCS).

C2SM currently hosts one PASC project and is involved in a second:

The ENIAC project: external page Enabling the ICON model on heterogeneous architectures
The PASCHA project: external page Portability And Scalability of COSMO on Heterogeneous Architectures

Past projects:

The Grid Tools project: external page Grid Tools: Towards a library for hardware oblivious implementation of stencil based codes
The CLAW project: CLAW provides high-Level Abstractions for Weather and climate Models

Enlarged view: Piz Daint at CSCS — Named after Piz Daint, a prominent peak in Grisons that overlooks the Fuorn pass, this supercomputer is a Cray XC30 system used by many C2SM-community members for high performance computing.
