Estudio del rendimiento de una aplicación que resuelve un problema numérico utilizando el método nodal y mimético. Implementación de nuevas versiones (secuenciales y paralelas).In the present work we analyze two finite difference methods for the propagation of acoustic waves proposed by Córdova et al. to optimize its performance. The computational domain is rectangular. The first of these methods uses a nodal grid and traditional compact finite differences that imply solving tridiagonal systems for numerical differentiation. The second method applies mimetic differential operators in explicit form in a center-distributed grid, avoiding the need to solver linear systems of equations. Starting from a basic MATLAB implementation of both method...
