EXCELLERAT presented at MWC Barcelona: Advancing Engineering Workloads

The Mobile World Congress (MWC26) took place from 2–5 March in Barcelona, Spain, and represents the global meeting point for digital innovation, advanced connectivity and AI-driven transformation. As industries accelerate towards a more intelligent and data-driven future, MWC provides the ideal stage to showcase how High-Performance Computing (HPC) and AI infrastructure enable genuine industrial breakthroughs – through hardware, software and high-end solutions.

This year, EXCELLERAT partner Arctur represented the EXCELLERAT P2 project at the fair, placing the EXCELLERAT Service Portal at the centre of its presentation. The portal serves as a single entry point to a distributed ecosystem of HPC expertise and services available to users engaged in engineering challenges across Europe.

The portal is specifically designed for:

• Technology providers seeking validation, benchmarking and optimisation on advanced EuroHPC JU infrastructure;
• Engineers requiring high-fidelity simulations, complex modelling and performance acceleration;
• Independent Software Vendors (ISVs) aiming to adapt and scale their applications for hybrid and GPU-accelerated supercomputing environments.

Through the portal, users can explore available services, connect directly with service owners and access advanced computing resources tailored to their specific needs.

The portal was demonstrated live at the stand, where visitors could explore its functionalities on a laptop, watch the EXCELLERAT promotional video and obtain further information from printed materials. Several visitors also expressed interest in becoming members of the EXCELLERAT Interest Groups.

Bringing HPC Success Stories to the Screen

Beyond presenting infrastructure and services at MWC, Arctur is also actively capturing the human and technological impact behind EXCELLERAT P2.

The team has joined forces with the Barcelona Supercomputing Center (BSC) to produce a new success story video showcasing the outstanding achievements of BSC researchers throughout the project’s lifetime. The video focuses on the BSC use case entitled “Enabling GPUs for Energy Efficient Aerodynamics Simulations of an Aircraft”.

Filmed at BSC – home to MareNostrum V, one of Europe’s most powerful supercomputers – the video highlights cutting-edge research in aerodynamics and aircraft design, specifically enabling high-fidelity aircraft simulations using advanced turbulence models while dramatically improving performance and energy efficiency.

Over the course of the project, BSC achieved:

• A hybrid workflow combining commercial software with in-house tools to generate high-quality, high-order meshes;
• Simulations running twenty times faster on a single accelerated node compared to a general-purpose CPU node;
• A GPU-based solver consuming between ten and twelve times less energy for the same simulation.
• These results demonstrate how advanced HPC architectures and optimised workflows can simultaneously enhance speed, accuracy and sustainability.

The video will be released in the coming weeks, offering a behind-the-scenes look at how European HPC excellence translates into tangible industrial and scientific impact.

If you are exploring how to scale simulations, accelerate AI workloads or optimise software performance for exascale, the EXCELLERAT Service Portal is your gateway to collaboration and innovation.
