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 13th Workshop on High Performance Computing in Meteorology took place from 3-7 November 2008.
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.
This workshop aims to provide a situation 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.
