La donnée sismique depuis sa conception (modélisation d’acquisitions sismiques), dans sa phase de traitement (prétraitement et migration) et jusqu’à son exploitation pour en extraire les informations géologiques pertinentes nécessaires à l’identification et l’exploitation optimale des réservoirs d’hydrocarbures (interprétation), génère un volume important de calculs. Nous montrons dans ce travail de thèse qu’à chacune de ces étapes l’utilisation de technologies accélératrices de type GPGPU permet de réduire radicalement les temps de calcul tout en restant dans une enveloppe de consommation électrique raisonnable. Nous présentons et analysons les éléments sous-jacents à ces performances. L’importance de l’utilisation de motifs d’accès mémoir...
