ESiWACE3 hackathon and eflows4HPC workshop

ESiWACE3, a Center of Excellence in simulation of weather and climate in Europe, is organising a hackathon on October 18-20, 2023, at CSC in Finland.

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 occur 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.

The hackathon is organised in tangent with the eFlows4HPC – ESiWACE - Climateurope2 communities workshop meeting on 17 October. You have the option to apply to attend either or both events. More information and registration for the workshop can be found here.

Who can apply?

Alongside the ESiWACE community, the event is open to anyone who is a member of an organisation eligible to receive an allocation for LUMI compute resources. We encourage groups with early career scientists, female researchers, and those from ITC countries to apply.

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 we strongly prefer open-source applications.
