Place: Quality Hotel™ Hasle Linie, Oslo, Norway
Time: Thursday 2022-06-02 12:00 CEST to Friday 2022-06-03 13:00 CEST

The introduction of accelerators and novel hardware architectures (e.g. GPUs, FPGAs and CGRAs) for HPC promises large performance increases, but also requires substantial refactoring and rewriting of existing code bases. 

Topics: Successfully onboarding experts for “porting” of large model systems to new hardware architectures, strategy, tooling, methods for refactoring, etc. This workshop will be used to inform the later workshops with regards to scope, content, and participants.
The workshop has received funding from Nordic E-Infrastructure Collaboration (NeIC). It is the first of four workshops organized by CSC – IT Center for Science Ltd in collaboration with United Weather Centres (UWC) on the subject of Energy-efficient Weather Prediction at Exascale.
 Note! This is a two-day lunch-to-lunch Workshop subsequent to, and co-located, with the MetCoOp workshop. We start with lunch on the 2nd and end with lunch on the 3rd
