Workshop description

Every second year ECMWF hosts a workshop on the use of high performance computing in meteorology. High performance computer architectures are becoming ever more complex which presents significant challenges for the ongoing development of operational meteorological applications. This workshop looked at the issues surrounding the scalability of NWP codes and the steps that will be required to enable us to use future large scale heterogeneous computer systems.

Workshop aims

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 were also be 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 presented their achievements in the development of parallel computing techniques and algorithms, and exchanged ideas on the use of supercomputers in future research. Computer scientists gave 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 were discussed.

The workshop consisted of presentations from invited speakers, plus a series of 30 minute contributions.
