From ARM to Python: What are the next steps for the European HPC?
We start our newsletter by celebrating collaboration and innovation across the EPICURE project. From successful hackathons to new training opportunities, our mission remains clear: to strengthen Europe's scientific computing ecosystem and enhance support for High-Performance Computing (HPC) users.
How can a Hackathon accelerate your HPC research?
At the EPICURE HPC in ARM Architecture Hackathon, researchers experienced firsthand how teamwork and hands-on learning can shape their approach to HPC. Developers and HPC users came together to optimise real-world code and ARM architectures, developing their own research.
Three researchers share their experiences, explaining how collaboration and mentoring helped them advance their research and connect with peers across Europe’s HPC community.
From collaboration to results: SIESTA Ported to ARM
Real results often start with collaboration.
During the same hackathon, Anthoni Alcaraz Torres, PhD from Institut Català de Nanociència i Nanotecnologia (ICN2) worked closely with the Deucalion team to successfully port the SIESTA code to ARM architecture, reaching significant performance improvements.
This breakthrough demonstrates how expert guidance, shared infrastructure, and open cooperation can accelerate scientific progress. Now, he shares his testimonial, showing how expert mentoring and collaboration can foster scientific progress.
Next event: Webinar on CPU-based Threading Models Application in Python for HPC Computing
EPICURE’s next training session focuses on threading models and techniques to improve Python performance in HPC environments.
Led by Veselin Kolev from the Discoverer Petascale Supercomputer , this lecture will explore three key approaches to overcoming Python’s Global Interpreter Lock (GIL), including OpenMP, PyOMP, and LLVM integration.
Upcoming: EPICURE Hackathon - Python Meets HPC
Following the webinar, EPICURE will host its next hackathon, Python Meets HPC, at KTH Royal Institute of Technology in Stockholm from December 10-12 2025.
This event will focus on Python optimisation, performance scalability, and collaborative coding. Participants can bring their own Python codebase or computational problem and work directly with mentors to turn it into a high-performance solution.
Together, these actions reflect EPICURE’s ongoing mission to advance scientific computing and support the European HPC community. We will continue creating opportunities for researchers, developers, and HPC users to learn, collaborate, and innovate together.
