French SME specializing in virtualization and system software for HPC, heterogeneous computing, and 5G infrastructure platforms.
Virtual Open Systems is a Grenoble-based SME specializing in virtualization, hypervisor technologies, and system software for high-performance and distributed computing platforms. They build software layers that allow heterogeneous hardware — processors, accelerators, memory nodes — to work together efficiently in datacenters and edge environments. Their work spans from exascale computing node design to 5G network infrastructure and disaggregated datacenter architectures, consistently focusing on the software glue that ties complex hardware together.
Core contributor across TAPPS (trusted CPS apps), SESAME (multi-tenant small cells), dReDBox (disaggregated datacenters), NGPaaS (platform-as-a-service), and 5GCITY — all requiring virtualization layers.
Participated in ExaNoDe and ExaNeSt (European exascale computing initiatives) and EVEREST (extreme-scale big data analytics), contributing OS, runtime, and MPI expertise.
dReDBox focused on disaggregated datacenter-in-a-box design; EVEREST targets heterogeneous platform programming; ExaNoDe addressed processor-memory node design.
SESAME (multi-tenant small cells), 5GCITY (5G infrastructure), and NGPaaS (next-gen platform services) all address telecom virtualization needs.
EVEREST (2020-2024) explicitly targets programmability via domain-specific languages, AI, and high-level synthesis for heterogeneous platforms.
Between 2015 and 2019, VOSYS concentrated on foundational HPC infrastructure — exascale node design, low-power processors, memory architectures, and classical runtime/MPI software stacks (ExaNoDe, ExaNeSt). In parallel, they built deep experience in telecom virtualization through 5G and edge computing projects. Their most recent project, EVEREST (2020-2024), marks a clear pivot toward programmability, domain-specific languages, AI-assisted design, and high-level synthesis — moving up the stack from raw infrastructure to developer-facing tools for heterogeneous platforms.
VOSYS is shifting from low-level system software toward higher-level programming tools and AI integration for heterogeneous computing, positioning them for the growing demand in hardware-software co-design.
VOSYS operates exclusively as a participant — they have never coordinated an H2020 project, preferring to contribute specialized virtualization and system software expertise to larger consortia. With 93 unique partners across 18 countries in just 8 projects, they are well-connected and clearly valued as a technical contributor that different consortia seek out. Their consistent role as a specialist partner suggests they are reliable, focused, and easy to integrate into diverse teams.
Broad European network of 93 unique partners across 18 countries, built through 8 projects — an unusually high partner-to-project ratio indicating participation in large, diverse consortia. Their Grenoble base places them in one of Europe's strongest computing and semiconductor ecosystems.
VOSYS occupies a rare niche as an SME that bridges virtualization, HPC, and telecom infrastructure — three domains that are rapidly converging. Their ability to provide the software abstraction layer between heterogeneous hardware and applications makes them a versatile partner for any project dealing with complex computing platforms. For consortium builders, they bring deep systems-level expertise without the overhead of a large organization, and their Grenoble location connects them to the CEA/INRIA/STMicro ecosystem.
