Underwater acoustic models are effective tools for simulating underwater sound
propagation. More than 50 years of research have been conducted on the theory and …

In modern physics it has become common to find the solution of a problem by solving
numerically a set of PDEs. Whether solving them on a finite difference grid or by a finite …

In numerical modeling, mesh quality is one of the decisive factors that strongly affects the
accuracy of calculations and the convergence of iterations. To improve mesh quality, the …

Abstract Partial Differential Equations (PDEs) are widely used to simulate many scenarios in
science and engineering, usually solved through iterative techniques (eg, Jacobi, Gauss …

In this paper we present grid methods which we have developed for solving direct and
inverse problems, and their realization with different levels of optimization. We have focused …

Abstract Accelerators like the Intel Xeon Phi aim to fulfill the computational requirements of
modern applications, including stencil computations. Stencils are finite-difference algorithms …

In addition to the hardware wall-time restrictions commonly seen in highperformance
computing systems, it is likely that future systems will also be constrained by energy …
