Discoverer+ AI Supercomputer Upgrade

Discoverer, Bulgaria’s EuroHPC petascale system at Sofia Tech Park, was upgraded in 2025 with four NVIDIA DGX H200 systems tied into its BullSequana XH2000 cluster. The refresh adds 32 H100 GPUs, new high-speed storage, and enhanced UPS capacity, transforming the facility into the Discoverer+ AI platform for neural network training, digital twins, and language technology in Southeastern Europe. Liquid-cooled CPU nodes and targeted cooling for the DGX racks keep the roughly 2 megawatt installation efficient while expanding access for regional researchers and startups.
