Before revision:  Starting from a single-core performance model we can describe the intra-chip saturation characteristics of the code and its optimal operating point in terms of energy to solution as a function of the propagation method, the clock frequency, and the SIMD vectorization.
After revision:  Starting from a single-core performance model , we predict the intra-chip saturation characteristics of the code and its optimal operating point in terms of energy to solution as a function of the propagation method, the clock frequency, and the SIMD vectorization.
