      Parallel Computing on Distributed-Memory Clusters
   for Long-Time Simulations of Calcium Waves in a Heart Cell

The flow of calcium ions in a heart cell is modeled by a system of
time-dependent reaction-diffusion equations. The highly non-smooth nature of
the source terms and the large number of calcium release sites requiring
high-resolution meshes are among the challenges for convergent and efficient
numerical methods for this problem. We will describe the techniques used for
long-time simulations of this model on distributed-memory clusters and
demonstrate that the simulations capture the relevant physical effect of
self-organizing waves of calcium. The solution of this problem is a
prototypical example for the power of using state-of-the-art hardware and
software in computational science.
