We aim to propose a prediction model of both time computation and energy consumption of linear algebra operations. Numerical experiments on a workstation equiped with two GPUs GTX275, have been performed on a set of matrices arising from the finite element discretization of the gravity equation with real data issued from the Chicxulub crater. The results exhibit performance, robustness and efficiency of Alinea library, our research group library, compared to Cusp library in terms of speed-up and energy consumption for double precision number arithmetics.
