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, supercomputers,...),
• the problems related to image assimilation.
