DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: To understand the macroscopic function of the human heart based on sub-cellular microscopic events, multi-scale analysis is =0Aindispensable. Our heart simulator uses the so-called homogenization method, where both the human heart and the myocardial cells are =0Amodeled and solved simultaneously by the finite element method. Because the contraction and deformation of each finite element in the =0Aheart model are governed by their respective cell model, the NDOF of all the cells becomes prohibitively =0Alarge. Furthermore, the phenomena are highly nonlinear and transient.=0AThis challenging problem has been tackled by our group for many years, and a novel algorithm to accelerate the computation was =0Aimplemented in the code. We have recently tested its performance using the T2K Open Supercomputer (Tokyo). A pulsation of the heart with =0Aa total NDOF of 160 million was successfully simulated using 6144 CPU cores in ten hours. Scalability and other computational =0Aperformances were measured and are discussed.
