12th Workshop on the Use of High Performance Computing in Meteorology

Every second year the European Centre for Medium-Range Weather Forecasts (ECMWF) hosts a workshop on the use of high performance computing in meteorology. This year’s workshop on High Performance Computing in Meteorology was held from 30 October to 3 November 2006.


At the workshop there was an emphasis on running meteorological applications at sustained teraflops performance in a production environment, and on the application specific developments required to move towards petaflops computing.

Our aim was to provide a venue where:

  • Users from our Member States and around the world could report on their experience and achievements in the field of high performance computing during the last two years; plans for the future and requirements for computing power were also presented.
  • Vendors of supercomputers had the opportunity to talk to managers and end users of meteorological computer centres about their current and future products.
  • Meteorological scientists could present their achievements in the development of parallel computing techniques and algorithms, and could exchange ideas on the use of supercomputers in future research.
  • Computer scientists could give an update on their efforts in providing tools which will help users to exploit the power of supercomputers in the field of meteorology.
  • The challenges of creating a computer centre infrastructure for HPC could be discussed.
