15th workshop on High Performance Computing in Meteorology

ECMWF hosted the fifteenth workshop on high performance computing in meteorology from 1 to 5 October 2012.


Every second year the European Centre for Medium-Range Weather Forecasts (ECMWF) hosts a workshop on the use of high performance computing in meteorology.

The emphasis of this workshop will be on running meteorological applications at sustained teraflops performance in a production environment. Particular emphasis will be placed on the future scalability of NWP codes and the tools and development environments to facilitate this as we move towards petaflop computing.

Our aim is to provide a venue where

  • Users from our Member States and around the world can 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 will also be presented.
  • Vendors of supercomputers will have the opportunity to talk to managers and end users of meteorological computer centres about their current and future products.
  • Meteorological scientists can present their achievements in the development of parallel computing techniques and algorithms, and can exchange ideas on the use of supercomputers in future research.
  • Computer scientists can 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 can be discussed.

The workshop consisted of a limited number of presentations from invited speakers, plus a series of 20 minute contributions. The morning of the final day was reserved for an open discussion session.
