Calcul haute performance pour la détection de rayon Gamma

Abstract : The new generation research experiments will introduce huge data surge to a continuously increasing data production by current experiments. This increasing data rate causes upheavals at many levels, such as data storage, analysis, diffusion and conservation.The CTA project will become the utmost observatory of gamma astronomy on the ground from 2021. It will generate hundreds Peta-Bytes of data by 2030 and will have to be stored, compressed and analyzed each year.This work address the problems of data analysis optimization using high performance computing techniques via an efficient data format generator, very low level programming to optimize the CPU pipeline and vectorization of existing algorithms, introduces a fast compression algorithm for integers and finally exposes a new analysis algorithm based on efficient pictures comparison.
