16th Workshop on High Performance Computing in Meteorology

The 16th ECMWF Workshop on High Performance Computing in Meteorology was held from 27 to 31 October 2014

Description

Every second year the European Centre for Medium-Range Weather Forecasts (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 will look 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 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 will consist of a limited number of presentations from invited speakers, plus a series of 30 minute contributions.
