Notes from the LS-DYNA Users Conference

I recently had the pleasure to go to Salzburg, Austria, and present in the 7th European LS-DYNA conference. LS-DYNA is a software solution from Livermore Software Technology Corporation (LSTC) that is a general purpose structural and fluid analysis simulation software package capable of simulating complex real world problems. It is widely used in the automotive industry for crashworthiness analysis, occupant safety analysis, metal forming and much more, and in most cases, LS-DYNA is being used in cluster environments as they provide the needed flexibility, scalability and efficiency for such simulations.

I have presented a paper on “LS-DYNA Productivity and Power-aware Simulations in Cluster Environments”. The paper was written by Mellanox, Dell and AMD with the help of Sharan Kalwani from GM and LSTC. The paper covers clustering interconnect analysis, CPUs performance, application and networking profiling and providing recommendations for increasing productivity (or jobs per day) while reducing power and cooling expenses. The paper can be downloaded from the “content/conferences” section on the HPC Advisory Council web site.

There were some very interesting sessions at the conference (beside mine …J). The automotive makers have expressed their need to be more economical and ecological (without compromising the brand names), the challenges of light weight design, increase demands from regulations, new materials, alternative drive engines, cost efficiency, increase safety, design of energy management equipment and much more. All of those items continue to increase the need for more simulation and higher complexity in order to create a design that fulfills those requirements and enables faster solution time to market. The paper that I presented provides information and guidelines on how to build next generation systems from one side, and how to optimize current systems for higher productivity on the other.

I also did manage to find some time in the late evening, and walk throughout the old city of Salzburg and see the house that Mozart was born in. It is a lovely city, with many sight seeing and nice places to sit down and drink beer (or coke, if you know me….).
