EXASCALE PERFORMANCE SYSTEMS - EXAPSYS IKE

Their core work

EXAPSYS is a Greek SME specializing in high-performance computing (HPC) performance optimization, hardware-software co-design, and energy-efficient computing architectures. They contribute technical expertise to Europe's flagship exascale computing initiatives, working on accelerator technologies, FPGA integration, and interconnect networks for next-generation supercomputers. Their work spans from processor ecosystem design to optimizing industrial applications on heterogeneous HPC platforms, making them a dedicated HPC engineering company embedded in Europe's push for sovereign exascale capabilities.

What they specialise in

How they've shifted over time

EXAPSYS entered the H2020 landscape in 2017 through EuroEXA, focused on foundational exascale co-design, scalability, and performance engineering. From 2021 onward, their portfolio expanded significantly — five projects launched in quick succession — shifting toward more applied concerns: heterogeneous systems, FPGA accelerators, interconnect networks, and open-source processor ecosystems. The recent emphasis on hardware accelerators, machine learning workloads, and the European Processor Initiative (EPI) pilot projects signals a move from general HPC performance research toward Europe's strategic digital sovereignty in processor and accelerator technology.

EXAPSYS is deepening its involvement in Europe's sovereign HPC hardware stack — expect continued focus on open-source processor architectures, AI-capable accelerators, and pilot exascale deployments.

How they like to work

EXAPSYS operates exclusively as a participant, never as coordinator, which is typical for a specialized SME contributing focused technical expertise to large-scale infrastructure initiatives. Their 64 unique partners across 13 countries indicate they work in very large consortia (averaging 10+ partners per project), consistent with flagship EU computing programs. This pattern suggests they are a trusted specialist that major HPC consortia invite for specific technical contributions rather than a project driver or strategic lead.

Extensive European network with 64 unique partners across 13 countries, built entirely through large flagship HPC consortia. Their partner base likely includes major European supercomputing centers, processor designers, and research institutions involved in the EPI and exascale programs.

What sets them apart

EXAPSYS is one of few Greek SMEs deeply embedded in Europe's most strategic exascale and processor sovereignty programs — participating in EuroEXA, European PILOT, EUPEX, and eProcessor simultaneously. Their combination of energy-efficient HPC design, accelerator expertise, and heterogeneous system optimization makes them a versatile technical partner for any consortium building European-origin computing infrastructure. For a small company, their presence across nearly all major EU exascale initiatives is a strong signal of recognized, specialized competence.

Highlights from their portfolio

• EuroEXA
  Their first and largest-funded project (EUR 253,734), a flagship co-design initiative for resilient exascale computing in Europe that established EXAPSYS in the HPC ecosystem.
• The European PILOT
  Second-largest funding (EUR 245,938), directly tied to the European Processor Initiative — positions EXAPSYS at the center of EU digital sovereignty efforts through 2026.
• eProcessor
  Bridges HPC with AI/deep learning workloads on open-source European processor ecosystems, representing EXAPSYS's expansion into machine learning infrastructure.
