Optimisation de l'utilisation du cache dans EUROPLEXUS

Abstract : in this paper we propose a new data structure organization for EUROPLEXUS: a simulation code developed by the CEA and dedicated to the analysis of fast phenomena of fluids and structures. The approach we propose is built so that the data accessed by the processor operating on a portion of the calculation for a time step are as contiguous as possible. This new distribution will help to minimize the number of cache misses compared to that obtained with the current organization of the data structure. Studies have validated the performance gain achieved with the new organization in the case of large scale problems.
