A Rapid Numerical Method for Computing Cardiac Models Based on MPI

摘要：

A heart is made up of billions of myocardial cells. Millions of computational cells need to be employed for simulating cardiac behavior. In order to improve the efficiency of cardiac simulation, in this paper, it is proposed a rapid numerical method of variable time step based on the operator splitting method according the characteristics of cardiac electrophysiology. This method reaches a precision of 3 digits after the decimal point, which satisfies the requirements of the cardiac electrophysiological simulation. At last, cardiac electrophysiological activities are simulated by self-adaptive variable time step method with parallel computers. The parallel program was executed on 32 CPUs and the speedup ratio arrived at 9.57.
