The science behind the HiDALGO2 innovations As global environmental, urban, and computing challenges expand, traditional computational frameworks frequently hit structural limits. Simulating entire cityscapes, tracing microscale atmospheric pollution, or predicting the flash progression of a wildfire requires massive processing capacity. However, raw power is no longer enough; next-generation engineering demands scalability, transparency, and energy awareness.

The HiDALGO2 Centre of Excellence is showcasing its latest research at the 16th International Conference on Parallel Processing and Applied Mathematics (PPAM 2026) in Poznań, Poland! A central highlight of our participation is the Advancements of Global Challenges Applications (AGCA) workshop, which brings together cutting-edge work across wildfire dynamics, urban microclimates, data analytics placement, and

HiDALGO2 team expands our understanding of how modern hardware and software innovations can optimise large-scale environmental simulations and AI-driven workflows. D3.6 deliverable: Innovative HPC Technologies and Benchmarking, currently under review by the EC, builds on our previous evaluations, as described in our previous reports D3.4 and D3.5  and focuses on state-of-the-art architectures from the world’s leading

Last Wednesday marked the successful conclusion of our intensive 2-day In-Person Project Plenary Meeting! A big thank you to Zoltán Horvárth and the Széchenyi István University (SZE) for being such incredible hosts and bringing the consortium together in Győr, Hungary. Over the two days (June 30 – July 1), led by our coordinator Marcin Lawenda,

The Repro-HPC Workshop concluded on Friday 26th, 2026, and the HiDALGO2 project was there co-organising and presenting our last paper. The participants shared insights and presented cutting-edge research on one of the industry’s most pressing challenges: the reproducibility crisis. Representing the University of Strasbourg (Unistra), Javier Cladellas presented our newly published paper: “Layered Reproducibility for

As high-performance computing (HPC) scales up to the exascale era, the demand for massive computing power has never been higher. For projects like HiDALGO2, which relies on extreme-scale simulations to address critical global challenges—such as urban air quality, wildfire propagation, and renewable energy optimisation—computational performance is non-negotiable. However, as our systems grow more powerful, managing their

As the European Union pushes toward its ambitious climate targets, the transition from fossil fuels to renewable energy sources (RES) has moved from a distant goal to a daily reality. In 2023, renewables accounted for 46.9% of the EU’s electricity production, already surpassing the 2030 target of 42.5%. However, this shift introduces a significant technical

This article was authored in Polish by Małgorzata Szołucha, and published on April 28, 2026 on NCBR In a world where climate change, severe weather events, and energy transformation are becoming civilizational challenges, science capable of understanding and predicting them is increasingly important. Supercomputers, artificial intelligence, and advanced numerical simulations are coming to the rescue.

HiDALGO2 advances how High-Performance Computing (HPC) can solve major global and environmental challenges. As true progress in this domain relies on collaboration, the consortium has been working together with CASTIEL 2 and contributing on the HPC in Europe Portal, showcasing how European Centres of Excellence (CoEs) unite to manage natural and man-made hazards. Following the

In a collaborative effort between HiDALGO2, SLB-analys, and ENCCS, researchers have developed a scalable HPC solution to simulate wind patterns across the entire city of Stockholm at unprecedented resolution. The Challenge Wind in urban environments significantly impacts inhabitant comfort and safety. Tall buildings can create “wind tunnels” where speeds far exceed averages, potentially putting pedestrians
