European projects

  • ERC Synergy EMC2 grant, Extreme-scale Mathematically-based Computational Chemistry, September 2019 – August 2025, Co-PIs: E. Cancès, L. Grigori, Y. Maday, and J. P. Piquemal, Sorbonne Université, Inria, Ecole Nationale des Ponts et Chaussées. The project aims to overcome some of the current limitations in the field of molecular simulation and aims to provide academic communities and industrial companies with new generation, dramatically faster and quantitatively reliable molecular simulation software.
  • NLAFET, Parallel Numerical Linear Algebra for Future Extreme-Scale Systems, funded by H2020 program, November 2015 – November 2018. Partners: Computer Science Department, Ume\aa University (Sweden) (Coordinator), Mathematics Department, Inria Alpines (France), University of Manchester (United Kingdom), Science and Technology Facilities Council (United Kingdom). Funding for Inria Alpines is 820 Keuros. The total person.months for Inria Paris is 122. The funding for Inria is to develop enlarged Krylov subspace methods and preconditioners based on low rank approximations.
