Qarnot specialises in High-Performance Computing (HPC) services for customers with extensive simulation needs. We work, for example, with MaiaSpace or Saint-Gobain to simplify the management of their simulation tasks thanks to our HPC Cloud platform, deployed on European infrastructures. This simple and intuitive platform enables our customers to significantly reduce the duration of their simulations (a major challenge for all companies in these sectors), and at a competitive cost. This is made possible by the fact that we deploy our own servers on sites where, thanks to our proprietary technology, we recover 95% of the energy consumed by the servers and re-inject it into heat networks, thus avoiding numerous costs.
