19th Workshop on high performance computing in meteorology

The EuroHPC initiative is a joint effort by the European Commission and 31 countries to establish a world-class ecosystem in supercomputing to Europe (read more at https://eurohpc-ju.europa.eu/. One of its first concrete efforts is to install the first three "precursor to exascale" supercomputers. Finland, together with 8 other countries from the Nordics and central Europe, will...

CINECA will host one of the pre-exascale systems procured by the JU EuroHPC. That system will be hosted on the campus of the Bologna Tecnopolo, which houses the ECMWF data center and will host various research and development laboratories. In addition to presenting the characteristics and development strategy of the HPC CINECA system, will be presented the research and development activities...

In 2019, the EuroHPC selected the Barcelona Supercomputing Center as entity to host one of the largest European supercomputers, MareNostrum5; this new MareNostrum will be one of the pre-exascale machines, with a peak performance of 200 petaflops (200 x 1015 floating-point operations per second). It is expected to come into operation on 31 December 2020. Its peak power of 200 petaflops will be...

The aim of the Destination Earth (DestinE) action is to support the EU’s green transition by providing a new Earth system simulation and observation capability. DestinE's initial focus is on the prediction of weather induced extremes and climate change adaptation through so-called digital twins. These twins will greatly enhance our ability to produce models with unprecedented detail and...

Digital twins are defined in many ways, but definitions usually end up something like "simulation of the real world constrained by real time data". This definition basically encompass our understanding of the use of weather and climate models whether using data assimilation or tuning to history. It would appear that we (environmental science in general and weather and climate specifically)...

We will give an overview of efforts to build earth system prediction models that are able to run at kilometer-scales on CPU, GPU and hybrid systems. The entire design and development process must be examined including algorithms, languages, tools and libraries, software approach, and other aspects in order to maximize the combination of computational performance, portability, productivity, and...
