Nous nous intéressons à la résolution en parallèle de système d’équations linéaires creux et de large taille. Le calcul de la solution d’un tel type de système requiert un grand espace mémoire et une grande puissance de calcul. Il existe deux principales méthodes de résolution de systèmes linéaires. Soit la méthode est directe et de ce fait est rapide et précise, mais consomme beaucoup de mémoire. Soit elle est itérative, économe en mémoire, mais assez lente à atteindre une solution de qualité suffisante. Notre travail consiste à combiner ces deux techniques pour créer un solveur hybride efficient en consommation mémoire tout en étant rapide et robuste. Nous essayons ensuite d’améliorer ce solveur en introduisant une nouvelle méthode pseudo...
