CH2011 – CSCS Supercomputers Compute Climate Scenarios for Switzerland

Sunday, October 2nd, 2011

It is getting warmer in Switzerland and dryer in summer, and climate change will also affect the frequency and character of extreme events.

Climate scientists of C2SM Competence Centre (Center for Climate Systems Modeling) and MeteoSwiss have generated the Swiss Climate Change Scenarios CH2011 which provide a new assessment of how climate may change over the 21st century in Switzerland. They are based on new generations of climate models with higher resolution, improved statistical methods, and an account of all recent relevant studies as well as the assessments by the Intergovernmental Panel on Climate Change (IPCC).

The necessary HPC infrastructure has been provided by CSCS, the Swiss National Supercomputing Centre on Cray supercomputers.

Job Offer at MeteoSwiss – Porting COSMO to GPU

Monday, June 27th, 2011

MeteoSwiss has two very interesting open positions related to the development of COSMO, the code used for the national weather forecasts.

The two new collaborators will be involved in the development of a code that will run on a very innovative hardware platform based on GPUs.  The project is named OPCODE (Operational COSMO Demonstrator) and is part of the Swiss initiative HP2C (High Performance and High Productivity Computing).

Short description of the two positions (in German):

  • Die erste Stelle analysiert den Teil des COSMO Codes zur Assimilation von Messungen, definiert die Design-Strategie für eine Portierung und Optimierung dieses Codes auf die neue Plattform und macht die Implementierung.
  • Die zweite Stelle analysiert die nötigen Änderungen in der Steuerung, portiert die Produktionskette auf die neue Plattform und optimiert diese insbesondere durch Parallelisierung bestimmter Postprocessing-Programme.

CSCS/ETH Zurich and MeteoSwiss Common Presentation in Bern

Sunday, June 20th, 2010

The president of ETH Zurich, Prof. Ralph Eichler invited last Wednesday, June 16 the Swiss parliamentarian to join over lunch to an introduction of ETH Zurcih activities in High Performance Computing. Prof. Thomas Schulthess presented  the activities of CSCS and the different elements of the Swiss National Supercomputing strategy (HPCN). Dr. Peter Binder of MeteoSwiss explained why supercomputer are essential for meteorology (CSCS is running two supercomputers for MeteoSwiss for 72 hours weather forecasts). Dr. Alessandro Curioni of IBM Rüschlikon explained how fast HPC is developing and that it is essential to regularly invest in new HPC systems.
