Video: Cosmology on the GPU

In this video from the GPU Technology Conference, Claudio Gheller from ETH CSCS presents: Cosmology on the GPU.

Numerical simulations represent one of the most effective tools to study and to solve astrophysical problems. Thanks to the enormous technological progress in the recent years, the available supercomputers allow now to study the details of complex processes, like galaxy formation or the evolution of the large scale structure of the universe. Sophisticated numerical codes can exploit the most advanced HPC architectures to simulate such phenomena and process and visualize their results. Enzo, Ramses and Splotch are prime examples of such codes. Work is ongoing to enable such codes to GPUs using the CUDA and OpenACC programming models. The accomplished refactoring work together with recent tests and results are presented.”
