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 11th workshop was held from 25 to 29 October 2004.
Description
The emphasis of this workshop was on achieving sustained teraflop performance in a production environment. Our aim at the high performance computing workshop 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
