dc.description.abstract | A mathematical model of Calcium Induced Calcium Release in a heart cell has been developed that consists of three coupled non-linear advection-di usion-reaction equations. A program in C with MPI based on matrixfree Newton-Krylov method gives very good scalability, but still requires large run times for ne meshes. A programming model with CUDA and MPI that utilizes GPUs on a hybrid node can signi cantly reduce the wall clock time. This paper reports initial results that demonstrate speedup using a hybrid node with two GPUs over the best results on a CPU node. | en_US |
