Performance of CFD codes on CPU/GPU clusters

Manfred Liebmann Zoltán Horváth

Publication Name: Aip Conference Proceedings

Publication Date: 2010-12-01

Volume: 1281

Issue: Unknown

Page Range: 1789-1792

Description:

The paper investigates the scalability of a parallel Euler solver, using the Vijayasundaram method, on CPU and GPU clusters. The aim of this research is to develop efficient parallel CFD codes on unstructured meshes. We present the relevant algorithms and some benchmark results, which show overall efficiency of the solver. © 2010 American Institute of Physics.

Large scale simulations of the euler equations on GPU clusters

Manfred Liebmann Craig C. Douglas Zoltán Horváth Gundolf Haase

Publication Name: Proceedings 9th International Symposium on Distributed Computing and Applications to Business Engineering and Science Dcabes 2010

Publication Date: 2010-11-05

Volume: Unknown

Issue: Unknown

Page Range: 50-54

Description:

The paper investigates the scalability of a parallel Euler solver, using the Vijayasundaram method, on a GPU cluster with 32 Nvidia Geforce GTX 295 boards. The aim of this research is to enable large scale fluid dynamics simulations with up to one billion elements. We investigate communication protocols for the GPU cluster to compensate for the slow Gigabit Ethernet network between the GPU compute nodes and to maintain overall efficiency. A diesel engine intake-port and a nozzle, meshed in different resolutions, give good real world examples for the scalability tests on the GPU cluster. © 2010 IEEE.
