GARCIA, Víctor M; VIDAL, Antonio M; LIBEROS, Alejandro  y  CLIMENT, Andreu M. Multi-GPU adaptation of a simulator of heart electric activity. Rev cuba cienc informat [online]. 2013, vol.7, n.4, pp. 100-111. ISSN 2227-1899.

The simulation of the electrical activity of the heart is calculated by solving a large system of ordinary differential equations; this takes an enormous amount of computation time. In recent years graphics processing unit (GPU) are being introduced in the field of high performance computing. These powerful computing devices have attracted research groups requiring simulate the electrical activity of the heart. The research group signing this paper has developed a simulator of cardiac electrical activity that runs on a single GPU. This article describes the adaptation and modification of the simulator to run on multiple GPU. The results confirm that the technique significantly reduces the execution time compared to those obtained with a single GPU, and allows the solution of larger problems.

Palabras clave : Electrocardiac simulation; GPU programming; ordinary differential equations.
