The Particle-in-Cell (PIC) method is used to study the phase space evolution on some systems made of charged particles. In this work, a bidimensional PIC model is presented to make the analysis of an electrostatic plasma that is result of an ablation laser process with an isotermic expansion. Some Cloud-In-Cell (CIC) techniques are used, the Fast Fourier(More)
Computational heart-tissue models envelope the solution of non-linear partial and ordinary differential equations which, after applying them certain discretization methods (finite difference, finite element) for its solution, result in a set of operations between matrices in the order of millions which results into programs with high execution times in(More)
Nowadays plasma has become of great importance in both scientific and industrial areas since nanostructures, used for creating small computational processing devices, are produced by pulse lasers. The Simulation of phenomena such as plasma consumes a big amount of CPUs execution time. This paper intends to suggest a parallel solution of the Semi-Lagrangian(More)
This article pretends to show how you can use GPU's to make the calculations of an LU decomposition and take advantage of the vectorial processors. At the first section we make an introduction of matrix factorization, in the second one we show some features of actual graphics cards, the third one we propose the problem to solve, in the fifth one we expose(More)
