The 3rd phase of the Centre of Excellence (CoE) in Simulation of Weather and Climate in Europe, ESiWACE3, presents its first hackathon,Running weather and climate models on LUMI”. The event aims at helping climate scientists port and optimise their codes to new architectures, such as LUMI, and will be the first of four hackathons organised through the project. It will take place on 18-20 October 2023 at the CSC-Tieteen Tietotekniikan Keskus Oy (CSC) premises in Espoo (Finland). It will be an on-site eventwith no remote participation possibilityand no attendance fee.

Who can apply?

Alongside the ESiWACE3 community, the event is open to anyone who is a member of an organisation eligible to receive an allocation for LUMI compute resources. Even if the training event targets weather and climate modellers at all career stages, we especially encourage groups with Early Career Scientists (ECS) to apply. Also, females and researchers from ITC countries are especially targeted communities.

The participants are expected to bring their own codes to the hackathon and work in teams with HPC experts. All the teams need to be committed, well prepared, know their applications in great detail, and have clear plans for what they want to achieve and an idea of how to do it. We are looking for proposals outlining a team effort of, for example, solving porting and/or performance issues with their code. Ideally, the scope should be limited so that good progress can be made during the hackathon with your team of typically two (2) to four (4) people.

Please note that there is a strong preference for open-source applications.

How to apply?

The application form to apply for participating in the hackathon is available here. It will be open until 31 July 2023. All the applications will be evaluated based on technical and scientific merits by experts of the ESiWACE3 Consortium.

The teams whose application successfully passes the selection process will be notified by 11 August 2023. They will need to register for the event to confirm participation within two weeks from notification of acceptance. The notification of acceptance will include all the necessary information on how to register.

“HPC workflows for climate modelling” workshop

Furthermore, the first ESiWACE3 Hackathon will be organised in tangent with the workshop “HPC workflows for climate modelling”, organised by the eFlows4HPC European HPC project in collaboration with ESiWACE3 and Climateurope2. It will be held at the Dogmi meeting room of CSC on 17 October 2023, just before the start of the ESiWACE3 hackathon. It is a one-day free event and aims to find synergies between the three communities. Even if the hackathon and the workshop are organised hand by hand, attendance at both events is independent; hence, there is the option to apply to attend either or both events. The registration form for the workshop can be found here.
