19th Workshop on high performance computing in meteorology

Bologna | 20-24 September 2021

Towards Exascale Computing in Numerical Weather Prediction (NWP)

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, themselves highly dependent on computing capability.

ECMWF's new high-performance computing facility is being installed at the Tecnopolo di Bologna. For the first time ECMWF's data centre will be separated from its headquarters and the Centre will function as a multi-site organisation. To mark this occasion, the 19th workshop on high performance computing in meteorology will take place in Bologna.

The theme of this workshop is "Towards Exascale Computing in Numerical Weather Prediction (NWP)"

We invite presentations addressing the following topics:

  •     International Exascale efforts in NWP
  •     Progress in HPC scalability
  •     Using AI and Big Data
  •     Hardware news

The workshop will consist of keynote talks from invited speakers, 20-30 minute presentations, a panel discussion and a visit to the new data centre.

Workshop aims

Our aim is to provide a forum where users from our Member States and around the world can report on recent experience and achievements in the field of high performance computing; plans for the future and requirements for computing power will also be presented.


The workshop will take place in Bologna.

Further details to follow.


This workshop is open to national weather services of ECMWF's Member and Co-operating States, to other major meteorological centres, and to users and manufacturers of super-computers.

Please note that we do not have any funding available for participant expenses for travel and attendance to the workshop.
