ICI, or Institut de Calcul Intensif, is a High Performance Computing Research Institute which was established at Centrale Nantes in January 2015. We make state-of-the-art numerical tools for massively parallel computing more accessible and develop innovative computing strategies integrating data and physical models for real-time simulation, addressing different three main areas: - High Performance Computing and massively parallel algorithms for computational mechanics, biomechanics, manufacturing, renewable energy and urban environment simulations - Big data analysis and predictive data modelling - Real-time simulation models based on Model Order Reduction techniques
