In this paper, we present a GPU cluster based Monte Carlo simulation of photon transport in multi-layered tissues. The cluster is composed of multiple computing nodes in a local area network (LAN) and each node is a personal computer equipped with one or several GPU for parallel computing. In this study, the MPI (Message Passing Interface), the OpenMP (Open Multi-Processing) and the CUDA (Compute Unified Device Architecture) technologies are employed to develop the program. It is demonstrated that this designing runs roughly N-1 times faster than that using single GPU when the GPUs within the cluster are of the same type, where N is the total number of the GPUs within the cluster.
Keywords:biomedical engineering; GPU cluster; photon transport in tissues; Monte Carlo simulation
