Bull to deliver AI-optimised supercomputer for Mimer AI Factory
EuroHPC JU (Joint Undertaking) has concluded the procurement of a new AI-optimised supercomputer for the Mimer AI Factory. Bull (formerly Eviden) has been selected to deliver the system. It will be installed at NAISS in Linköping later in 2026.
“As one of the first AI-only systems deployed by EuroHPC JU, this is an important milestone for NAISS and the AI Factory infrastructure. It will enable SMEs, public sector actors, and researchers to rapidly deploy AI workloads. It is also a key enabler to develop sovereign language models and deliver impact in areas such as life sciences, materials science, and autonomous systems,” says Linköping University Professor and NAISS Director Erik Lindahl.
“We are excited to work with Bull on a platform that combines performance with a strong commitment to open source to strengthen Sweden’s capacity for secure AI.”
The total value of the contract, including acquisition, delivery, installation, and maintenance, is around EUR30 million. Funding is shared 50/50 between Sweden (through the Swedish Research Council) and EuroHPC (through the Digital Europe Programme). NAISS and EuroHPC will each be controlling and allocating half of the resources on the system.
The liquid-cooled system will be based on Bull’s latest BullSequana XH3500 architecture, specifically designed for advanced AI workloads. The solution combines cloud-enabled supercomputing resources with large-scale storage for sensitive data, advanced software layers, and dedicated vertical expertise to support AI use-case design and deployment.
Key facts:
- Bull Sequana XH3500, 100 nodes equipped with GB200 for a total of 400 GPUs
- Small CPU partition with Grace CPUs
- IBM ESS6000 storage connected to compute via S3 gateway servers
- Ethernet 400 Gbit/s interconnect using Nokia 7220 switches
- Proposed Software stack based on OpenShift for Kubernetes, Bull SMC for system management, IBM GKLM for encryption keys and BullSequana Pro AI
