Short presentation

The domain of the PEQUAN team deals with computer arithmetic and scientific computing. The team has developed the CADNA library based on a probabilistic approach of round-off error propagation. The skills of the team cover:

  • the development of numerical algorithms using floating point or fixed point arithmetic and their numerical validation,
  • the performance optimization of numerical applications on various architectures (multicore processors, GPUs, computing grids, supercomputers,...),
  • the numeration systems and the associated algorithms in relationship with cryptology or signal processing,
  • the problems related to image assimilation.

Computer arithmetic, Rounding errors, Numerical validation, Numerical quality, Heterogeneous and multimodal data, Distributed numerical computing, Asynchronous numerical algorithms, Reliable results, Symbolic/numerical algorithms, Arithmetic operators for cryptography.

No event planned at present.
