14th 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. The 14th ECMWF Workshop on High Performance Computing in Meteorology was held from 1 to 5 November 2010.

Description

The emphasis of this workshop was on running meteorological applications at sustained teraflops performance in a production environment. Particular emphasis was placed on the future scalability of NWP codes and the tools and development environments to facilitate this.

The 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.

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.
