Les performances des applications parallèles de type SPMD (Single Program Multiple Data) sont fortement affectées par les facteurs dynamiques de déséquilibre de charge. L’utilisation d’un algorithme d’équilibrage de charge approprié est essentielle pour éviter ou minimiser les effets indésirables causés par ces facteurs. L’objectif principal de ce travail est d’évaluer les performances de certaines stratégies d’équilibrage de charge basées principalement sur l’approche maître-esclave. Des versions statiques et dynamiques d’algorithmes largement utilisés dans la littérature ont été mises en œuvre, en proposant des adaptations et des optimisations visant à améliorer les performances des applications parallélisées. Les performances des algorithmes ont été analysées à partir de l’exécution de deux applications réelles, avec des caractéristiques différentes et dans des environnements d’exécution différents. Les résultats obtenus et les analyses effectuées sur ceux-ci montrent l’importance du choix approprié d’une stratégie d’équilibrage de charge, face à un scénario spécifique pour l’exécution d’une application SPMD.
