he report describes the activities carried out within the NEMO Consortium commitment. They refer to the performance evaluation and the comparison of the NEMO version 3.3 and the NEMO version 3.3.1. The main differences between two versions are related to the memory management and the allocation of the data structures. The NEMO ver. 3.3.1 replaces the static memory array allocation with a dynamic one. This approach brings some relevant benefits, such as the run time evaluation of the best domain decomposition. On the other hand, the dynamic array allocation introduces some lose of computational performance. The aim of this work is to evaluate the difference between the two versions from a computational point of view
