Abstract :
Three-dimensional finite-difference bidomain models of cardiac tissues can lead to a large number of equations for which an effective solution with the computational power of conventional computers may be difficult. Here, the authors describe the application of a massively parallel computer to provide the memory and reduction in solution time for solving large finite-difference bidomain problems. The finite-difference grid can be mapped effectively to the processors of the parallel computer, simply by mapping one node to one processor. The parallel finite-difference algorithm for a general three-dimensional bidomain model is presented together with test results
