Communication efficient work distributions in stencil operation based applications
Original language description
In recent years, the use of accelerators in conjunction with CPUs, known as heterogeneous computing, has brought about significant performance increases for scientific applications. One of the best examples of this is lattice quantum chromodynamics (QCD), a stencil operation based simulation. These simulations have a large memory footprint necessitating the use of many graphics processing units (GPUs) in parallel. This requires the use of a heterogeneous cluster with one or more GPUs per node. In orderto obtain optimal performance, it is necessary to determine an efficient communication pattern between GPUs on the same node and between nodes. In this paper, we present a performance model based method for min- imizing the communication time of applications with stencil operations, such as lattice QCD, on hetero- geneous computing systems with a non-blocking InfiniBand interconnection network. The proposed method is able to increase the performance of the most computationally intensive
