OL écrit :Et moi je te répond que dans le monde moderne sur une machine de bureau actuel le parallèlisme pour faire du calcul (on parlait bien de cela il me semble) se fait par thread pas par process, faudrait te mettre à jours.Bien pour faire du traitement d'images, et de la vision artificielle,
qui sont des calculs assez complexes, principalement sur des entiers,
j'utilise les ressources parallèles des machines multi-coeurs, en
lançant des processus concurrents. Il suffit souvent de découper les
images, et de lancer des calculs identiques, sur des morceaux d'images,
et de regrouper les calculs sur les différents morceaux indépendants.
Non et de très loin.
Dans ce cas le thread est plus recommandé mais c'est plus compliqué à programmer.Comme je l'ai écrit par précédemment, quand on fait de la programmation scientifique (ce qui comprend le traitement d'images) on n'essaie pas de gérer soi-même les threads, on utilise OpenMP qui le fait pour nous à partir de quelques directives très simples:
