In this work we present our work in order to benefit from modern cluster in our simulations. Mainly we introduce a new data structure to face efficiently NUMA effects on clusters and also we show an hybrid parallelsim openMP/MPI to run efficiently dislocation dynamics simulations.

Mots clés: openMP; MPI; data structure; cache oblivious; dislocation dynamics
