ARCTUR RACUNALNISKI INZENIRING DOO

Their core work

Arctur is a Slovenian SME specializing in high-performance computing (HPC) services, making supercomputing power accessible to small and medium enterprises across Europe. They provide cloud-based HPC infrastructure, simulation tools, and data analytics platforms that allow industrial users — particularly in manufacturing, automotive, and aeronautics — to run complex engineering simulations without owning expensive hardware. Their core business model bridges the gap between world-class computing resources and the SMEs that need them but cannot afford dedicated infrastructure.

What they specialise in

How they've shifted over time

In their early H2020 period (2015–2018), Arctur focused on foundational HPC infrastructure: exascale I/O, additive manufacturing simulation, and building networks to bring supercomputing to SMEs. From 2018 onward, their work shifted toward structured HPC competence centres (EUROCC, FF4EuroHPC), EuroHPC co-design, and scaling their SME support model across Europe. A surprising late addition is the FoodE project (2020), suggesting they are beginning to apply their data analytics capabilities to non-traditional domains like urban food systems and citizen science.

Arctur is consolidating its position as a European HPC service provider for industry while cautiously expanding into data-driven applications beyond engineering, such as food systems and citizen science.

How they like to work

Arctur primarily operates as a participant in large consortia — 7 of 9 projects — but has demonstrated coordination capability with SESAME NET. With 196 unique partners across 34 countries, they maintain an exceptionally broad network for an SME, indicating they are a trusted and well-connected partner rather than a niche specialist. Their role tends to be providing HPC infrastructure and services within larger research or innovation initiatives rather than leading the scientific agenda.

With 196 unique consortium partners across 34 countries, Arctur has one of the broadest collaboration networks of any Slovenian SME in H2020. Their partnerships span the full European HPC ecosystem, from national supercomputing centres to industrial end-users.

What sets them apart

Arctur occupies a rare niche: a small company that acts as a bridge between Europe's supercomputing infrastructure and the SMEs that need it most. Unlike large HPC centres that focus on academic users, Arctur's consistent focus has been on making simulation and data analytics practical for industrial companies. Their Slovenian base, combined with deep involvement in pan-European HPC initiatives (EuroHPC, Fortissimo), gives them both local agility and continent-wide credibility.

Highlights from their portfolio

• Fortissimo 2
  Largest single EC contribution (EUR 611,194) — focused on bringing simulation and modelling services to manufacturing SMEs through cloud HPC.
• SESAME NET
  Only project where Arctur served as coordinator, building a network of supercomputing expertise specifically designed for SME access.
• EXCELLERAT
  Centre of Excellence for engineering applications connecting HPC to automotive, aeronautics, and combustion — their highest-profile domain-specific project.
