19th Workshop on high performance computing in meteorology

Bologna | 14-18 September 2020


COVID-19 (coronavirus) update

17 March 2020

As the situation around COVID-19 (coronavirus) continues to evolve we understand you will have questions about its impact on ECMWF events. At this stage, no events have been cancelled and we hope all scheduled events will take place as planned.

We are monitoring the situation closely and will notify registered participants if we need to postpone an event or deliver it virtually rather than physically. Due to this uncertain situation, ECMWF recommends that participants ensure that any travel and accommodation arrangements are made with appropriate cancellation policies until further notice.

Thank you for your understanding; for the most up-to-date information, continue checking this webpage.

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 will be installed at the Tecnopolo di Bologna in 2020. 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 at the I Portici Hotel, located in the centre of Bologna.


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.

Registration is 150 GBP/participant. The registration fee includes two evening receptions, one evening dinner and coffee-breaks.

The registration fee will be waived for representatives of ECMWF's Member and Co-operating States and accepted speakers.

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

Registration and abstract submission

If you wish to attend this workshop, please complete the registration form before the registration deadline which is 18 May 2020.

We are seeking abstract submissions for 20-30 minute oral presentations. Contributions should focus on the above key topics. If you wish to submit an abstract, please complete the abstract submission form before 18 May 2020.


Bologna Marconi Airport (BLQ) is 4 miles from the centre of Bologna (15 minutes by bus).

Please note that the Bologna Marconi Airport will be closed for maintenance works from 16 to 21 September 2020. If travelling by air during this period we recommend using Florence Airport (FLR) which is the next most convenient airport in terms of distance and train transportation. ECMWF will provide a complimentary shuttle service from the workshop venue to Florence airport (FLR) when the workshop closes on Friday 18 September.

Bologna central train station connects to several international airports including Florence (FLR), Milan Malpensa (MXP), Rome (FCO) and Venice (VCE). We are investigating and will provide further train travel information for delegates.
