Three-Dimensional Cardiac Electrical Activity Simulation on Cluster and Grid Platforms

Simulation of action potential propagation on cardiac tissues represents both a computational and memory intensive task. The use of detailed ionic cellular models, combined with its application into threedimensional geometries turn simulation into a problem only affordable, in reasonable time, with High Performance Computing techniques. This paper presents a complete and efficient parallel system for the simulation of the action potential propagation on a three-dimensional parallelepiped modelization of a ventricular cardiac tissue. This simulator has been integrated into a Grid Computing system, what allows an increase of productivity in cardiac case studies by performing multiple concurrent parallel executions on distributed computational resources of a Grid.
