Scaling Applications to a Thousand GPUs and Beyond
Abstract:

Discover how to scale scientific applications to thousands of GPUs in parallel. We will demonstrate our techniques using two codes representative of a wide spectrum of programming methods. The Ludwig lattice Boltzmann package, capable of simulating extremely complex fluid dynamics models, combines C, MPI and CUDA. The Himeno three-dimensional Poisson equation solver benchmark combines Fortran (using the new coarray feature for communication) with prototype OpenMP accelerator directives (a promising new high-productivity GPU programming method). We will present performance results using the cutting-edge massively-parallel Cray XK6 hybrid supercomputer featuring the latest NVIDIA Tesla 2090 GPUs.
