Solutions that can scale with growing needs

ESI Group : 26 May, 2005  (New Product)
Manufacturers today struggle to reduce delays in product design as they work with more and more refined models. To keep up with these time and quality constraints, they look for solutions that can scale with their growing needs. Silicon Graphics and ESI Group (ISIN FR0004110310) today announced they have pushed scalability to new extremes, enabling users to run a crash simulation model eight times larger than today's standard industry practice. The achievement represents a significant competitive advantage for automotive designers confronted with ever growing model sizes and shrinking turnaround time.
Manufacturers today struggle to reduce delays in product design as they work with more and more refined models. To keep up with these time and quality constraints, they look for solutions that can scale with their growing needs. Silicon Graphics and ESI Group (ISIN FR0004110310) today announced they have pushed scalability to new extremes, enabling users to run a crash simulation model eight times larger than today's standard industry practice. The achievement represents a significant competitive advantage for automotive designers confronted with ever growing model sizes and shrinking turnaround time.

Today the typical full car simulation model size is 1.1 million elements and can be run overnight. In recent tests, SGI with ESI Group successfully ran a model of 9.1 million elements at 338.20 gigaflops per second performance on a SGI Altix 3700 Bx2 server with 512GB memory running PAM-CRASH 2004 on 512 Intel Itanium 2 processors.

On the high-density Altix system, SGI and ESI Group were able to deliver the crash case results on model with 9.1 million elements, 8x that of a typical model, within 8 hours 11 minutes, enabling engineers to use the results of the full case computation with increased precision as early as the next morning. This means that an engineer can run a model eight times more complicated within essentially the same time as a standard sized model.

This outstanding result is made possible with a complement of the SGI Altix NUMAflex architecture with huge globally addressable shared-memory and PAM-CRASH software's enhanced scalability. The solution enables engineers to cope with the expected growth of model size due to factors like model refinement, increase model fidelity, and modeling material rupture. Additionally, insurance companies rely on simulations to evaluate risks, including specific car-to-car and car-to-passenger interactions. With such a configuration car manufacturers can now address new applications such as the simulation of a detailed car body with trim, or investigate critical zones for rupture prediction.

'While high-performance computing hardware has moved toward scalable systems, ESI Group has invested in a new architecture for its crash test solution solver,' said Vincent Chaillou, President and Chief Operating Officer, Product Operations, ESI Group. 'The new generation of our parallel solver, first delivered in 2002, offers unprecedented scalability for full car model computations.'

'The Altix server family offers tremendous flexibility in configuring for application-specific needs,' said Christian Tanasescu, Director of Engineering, Simulation Applications, SGI. 'Altix can be used in single system image configurations up to 512 processors or as a supercluster that equips up to 2,048 processors with globally addressable memory. With an industry-leading communication latency of less than 1 microsecond, SGI's NUMAflex interconnect enables PAM-CRASH to scale to dramatic new heights.'
