François Févotte
François Févotte is co-founder and Chief Scientist of TriScale innov, a start-up dedicated to technical and scientific computing. Prior to that, he graduated in 2008 with a PhD in applied mathematics from the CEA and spent more than ten years with a team dedicated to numerical analysis and modeling in the R&D division of EDF (France's main electric utility). François' approach aims at achieving high performance in scientific software by focusing the effort where it matters most. This includes using state-of-the art numerical techniques in combination with FP-aware algorithms and implementations targeting modern hardware architectures.
Sessions
This talk will present how basic operations on vectors, like summation and dot products, can be made more accurate with respect to Floating-Point arithmetic by using compensated algorithms. The proposed implementation is available in the AccurateArithmetic.jl package, and leverages SIMD instructions in order to achieve high performance on modern hardware architectures.
