The LUMI supercomputer, situated in Kajaani, Finland, represents a significant collaborative achievement by European nations in high-performance computing. Funded by the European High-Performance Computing Joint Undertaking (EuroHPC JU) along with resources from multiple consortium countries such as Finland, Belgium, the Netherlands, and others, LUMI serves as a central tool for scientific and technological advancements aimed at addressing major global challenges.
Ranked as the eighth fastest supercomputer in the world and the fastest in Europe on the Top500 list as of November 2024, LUMI delivers sustained computing performance at 380 petaflops—equivalent to the combined power of approximately 1.5 million high-end laptops. Its architecture is built on the HPE Cray EX platform and utilizes AMD´s EPYC CPUs and Instinct MI250X GPUs, enabling unparalleled processing speed crucial for demanding workloads in areas such as climate modeling, molecular research, and Artificial Intelligence.
LUMI is lauded not only for its computational prowess but also its commitment to energy efficiency and sustainability. According to the Green500 list, it ranks as the twenty-fifth most energy-efficient supercomputer globally. The system operates entirely on hydropower, and sophisticated heat recapture technology allows excess thermal output from the facility to provide heating for around 100 homes in Kajaani, contributing to a more sustainable local environment while powering research vital to Europe and the world.
